Basic Power Definitions & Industry Terms
No, the power sensors are internal.
Not reliably. The current consumed varies widely depending on how many accessories are installed. The placard generally displays the maximum power the unit is rated to draw.
Heat is measured in watts. Power is measured in watts. Almost all electrical energy used in computing is converted to heat. A typical computer power supply is about 70-80% efficient. This means that for every 100 watts it draws, between 20 and 30 watts are converted directly into heat without ever being used by the computer. As the computer processes information, the rest of the power is dissipated throughout the system as heat. Since all power can be counted as heat, adding the watt ratings of all equipment in a cabinet will give a relatively 1:1 relationship to heat generated. I.E. 40 servers x 300 watts each = 12,000 watts (12kW) heat.
Amperes (or Amps) are the standard measure of electrical current. Much like water fl owing through a pipe, Amps measure how much electricity is moving through a wire at any given time. The Amp draw of a circuit is dependent on the needs of the devices plugged into it, and is limited by the branch circuit protection.
Volts are the standard measure of electrical potential and are a fixed value for every circuit. Volts are measured with respect to a reference point (usually between the two respective conductors of the circuit). Voltage is analogous to pressure in a water pipe. Higher pressures, or higher voltages, allow more energy to flow within a given amount of time for a given wire size. Standard voltages present in most data centers are 120V and 208V in the U.S., and 230V in continental Europe.
Watts are a measure of the total power being consumed by a system. The calculation is: Watts = Volts x Amps x Power Factor.
The acronym means Root-Mean-Squared. It is used to indicate a calculated, highly accurate value versus an instantaneous estimate.
Apparent Power is the calculation of Volts x Amps. Apparent power is measured in units of Volt-Amps (VA). Apparent power is used to measure the draw from a utility or for sizing wires and circuit breakers.
DCiE stands for Data Center Infrastructure Efficiency. DCIE is IT Power divided by Total Facility Power, expressed as a percent (%). DCIE is the inverse of PUE.
Power Factor is used to define the ratio of Real Power to Apparent Power, or how much of the power is being used to do work. Power Factor is therefore a number zero to one but may also be displayed as a percentage. Lower power factors have the additional cost of energy loss in the distribution system and require a larger infrastructure.
PUE stands for Power Use Effectiveness. PUE is a measure of how efficiently power is being used in a data center, and is becoming the standard benchmarking metric in most data centers. PUE is determined by dividing the total facility power use by the IT equipment load. Because the power distribution within the building has several points where losses occur (UPS, transformers, wire runs), the ideal place to measure the IT power load is at the cabinet level within the power strip. These readings can be collected and aggregated to determine the IT power load. Once an initial assessment of PUE has been made, efforts can be made to improve PUE by applying various methods to improve operational efficiencies in the data center.
Real Power is sometimes referred to as ‘True’ power. Real Power is the actual power being used by the load and is measured in Watts (W). Real Power takes into account the phase angle of the current and this is typically the nameplate rating on IT equipment.
An absolute must in mission-critical applications, the general concept behind power redundancy is to connect critical equipment to two independent power sources. If one line of power is interrupted, the second is able to power the critical equipment. This is accomplished in the following. First, equip the cabinet with two PDUs, each of which is capable of handling the power requirements of the entire cabinet. Plug one PDU into the first power source and the other into the alternate. Plug each piece of equipment into both (most data center equipment today has multiple power supplies as a fail-safe).
Apparent power is the calculation of volts times amps. Real power is RMS power (real-time) plus the power factor calculation.
Current Monitoring (EM) Products
No, the power sensors are internal.
Current Monitoring (EM) & most R-Series units have field-upgradeable firmware. The Satellite Power Monitoring Plus (RSS) units function as external sensors and do not contain their own firmware, therefore they are not field upgradeable. Updates are posted at: http://www.geistmfg.com/geistus/docs/downloads.htm
Yes, this information is stored in flash memory on R-Series and Current Monitoring (EM) units.
All Geist units with an Ethernet port can interface with SNMP software. The Satellite Power Monitoring Plus (RSS) PDU does not directly interface with the software but can do so via an Ethernet-enabled R-Series unit.
Yes, R-Series and Current Monitoring (EM) units can report data via SNMP.
Not reliably. The current consumed varies widely depending on how many accessories are installed. The placard generally displays the maximum power the unit is rated to draw.
The Current Monitoring (EM) and R-Series (RCX, RSM, RCM-O, RCU-O, FC, RSO, RSMINI and RSMICRO) units can be configured to send an email and/or send a SNMP trap, however paging must be activated via user-provided SNMP software and script. Alarm Notification Options include the following:
Disabled
Send Email
Send SNMP Trap
Send Email and SNMP Trap
Buzzer
Buzzer and Send Email
Buzzer and Send SNMP Trap
Buzzer and Send Email and Send SNMP Trap
*Note that most cell phones and pagers can receive emails, making text messaging via email a viable option.
All Current Monitoring (EM) and R-Series units are FCC tested and comply with FCC Part 15 Class A regulations. FCC testing is not required on the Satellite Power units because they communicate through FCC compliant R-Series units.
If the condition self corrects, the alarm condition will correct itself. If you are using SNMP alarms, you will receive a "cleared" notification for each alarm as it corrects itself. If the alarm condition will not self-correct or the conditions for an alarm have changed, the alarm threshold may be adjusted to reflect the new conditions. In this case you will not receive a "cleared" notification.
For Current Monitoring (EM) units, the MIB is found on the units web page.
Current Monitoring (EM) units use a 10MB/s Ethernet interface. Therefore they are not compatible with a 1000/10000 switch. A suggestion would be to add a 10/100/1000 switch to connect Current Monitoring (EM) units to the network.
Current Monitoring (EM) units use a 10Mb/s Ethernet interface. In Firmware Version 1.xx the TCP/IP stack may not negotiate with 10/100/1000 equipment properly. Firmware Version 2.xx has been updated to address this issue. Updates are posted at: http://www.geistmfg.com/geistus/docs/downloads.htm
Telnet is supported on R-Series Version 2.XX and 3.XX devices. Telnet is not supported by Current Monitoring (EM) units. To access units via Telnet, use the Administrator level username/password. Available commands and information vary by unit type. Enter "help" after logging in to see available commands.
On R-Series Version 2.XX devices, "report" will provide an easy to read status report.
On R-Series Version 3.XX devices, "sensors" will provide a similar report.
Most SNMP software requires that the appropriate MIB file be placed in a specified directory. This is done so that the SNMP software knows how to read the SNMP information available from the R-Series or Current Monitoring (EM) units. Some SNMP software (i.e. What's Up Gold) requires a program to be run to import the information in the MIB and make it useful.
The acronym means Root-Mean-Squared. It is used to indicate a calculated, highly accurate value versus an instantaneous estimate.
10/100Mbps auto-sensing.
DHCP, HTML, HTTP, ICMP, SNMP, TCP/IP, UDP and XML.
R-Series ProductsThe problem is most likely that one of your external sensors has a crossed wire. Follow this procedure to test the sensors: - Unplug all of the sensors and check the "Remove all unplugged devices" check box on the Display page.
- Plug in one sensor and wait for it to be detected.
- If the sensor works, leave it plugged in and plug in another sensor.
- If the sensors stop responding, the last sensor to be plugged in is faulty. If your unit is under warranty, call support for a replacement.
Most R-Series units support HTTP and HTTPS (secure) web access. The Satellite Power (DM, RSS, RS2) units are connected and viewed as an external sensor on RSM, RSE, RCM, RCM-O, RCU, RCU-O, RSMINI and RSMICRO units.
No, the power sensors are internal.
Current Monitoring (EM) & most R-Series units have field-upgradeable firmware. The Satellite Power (DM, RSS, RS2) units function as external sensors and do not contain their own firmware, therefore they are not field upgradeable. Updates are posted at: http://www.geistmfg.com/geistus/docs/downloads.htm
R-Series units contain a telnet interface for reporting of data and calibration of external airflow sensors. All other administrative functions are accessible through the web interface.
Yes, this information is stored in flash memory on R-Series and Current Monitoring (EM) units.
Most R-Series units provide graphed data via the onboard web page. The Satellite Power (DM, RSS, RS2) unit reports data to the RSM, RSE, RCM, RCM-O, RCU, RCU-O, RSMINI or RSMICRO units. Data from the Satellite Power PDU will show as a separate graph on these units.
The console software can be used to push alarm configuration settings to multiple units. At this time there is not a way to mass configure network/account/device settings.
All Geist units with an Ethernet port can interface with SNMP software. The Satellite Power PDUs do not directly interface with the software but can do so via an Ethernet-enabled R-Series unit.
Yes, R-Series and Current Monitoring (EM) units can report data via SNMP.
Information collected by R-Series units can be exported to Excel or another spreadsheet software by downloading the CSV log file from the unit's Logs page.
Yes, they will appear on the site shortly after being connected.
The test alarms function can be used to turn the buzzer off remotely. The following steps will lead you through this process. - Go to the Alarms page.
- Scroll down to the Test Alarms section.
- Pick one of the internal sensors from the Sensors drop-down box.
- From the Alarm State drop-down, choose Buzzer.
- Select Clear from the Trap Type drop-down.
- Click on the Test button.
- The buzzer should turn off in a few seconds.
No, the "output" of the I/O ports is a steady 5V via a pull-up resistor that is usable for detecting a dry contact closure (such as a door sensor or water sensor).
A Satellite Power PDU will function as a standalone PDU, however none of the monitoring capabilities will be active.
The RSM, RCX, RSS, RCM, RCM-O, RCU and RCU-O monitor power and provide RMS Volts, Amps and Watts for each circuit monitored. The RSS, DM and RS2 require an Ethernet-enabled R-Series unit to report its data. RCU and RCU-O also feature outlet level monitoring.
R-Series units contain three-level password protection: View Only, Control and Administrator.
RSM, RSE, RCM, RCM-O, RSMINI and RSMICRO can support up to 16 digital sensors, depending on aggregate sensor cable length. RCX does not support external sensors. RCU, RCU-O only supports 15 external sensors.
R-Series units with firmware versions of 2.48 and higher support SSL.
The Current Monitoring (EM) and R-Series (RSM, RSE, RCX, RCM, RCM-O, RCU-O, FC, RSMINI and RSMICRO) units can be configured to send an email and/or send a SNMP trap, however paging must be activated via user-provided SNMP software and script. Alarm Notification Options include the following:
Disabled
Send Email
Send SNMP Trap
Send Email and SNMP Trap
Buzzer
Buzzer and Send Email
Buzzer and Send SNMP Trap
Buzzer and Send Email and Send SNMP Trap
*Note that most cell phones and pagers can receive emails, making text messaging via email a viable option.
Temperature sensors are factory calibrated by the IC manufacturer and should maintain accuracy of /- 0.5 degrees Celsius for the better part of a decade. Remote airflow sensors are calibrated at Geist but, due to the nature of the sensor, may need to be calibrated by the end-user for more consistent readings.
Yes
No. If a display is not needed, the RSE-B model (with no display capability) should be used. If a display is needed, the RSE2X16 has its own internal display and should be used.
No, the RCX has no RJ-12 ports for connecting external sensors.
All Current Monitoring (EM) and R-Series units are FCC tested and comply with FCC Part 15 Class A regulations. FCC testing is not required on a Satellite Power unit because it communicates through FCC compliant R-Series units.
If the condition self corrects, the alarm condition will correct itself. If you are using SNMP or e-mail alarms, you will receive a "cleared" notification for each alarm as it corrects itself. If the alarm condition will not self-correct or the conditions for an alarm have changed, the alarm threshold may be adjusted to reflect the new conditions. In this case you will not receive a "cleared" notification.
To reset a lost password, please contact customer service at 800-432-3219 with your device's serial number.
For R-Series units the MIB can be found in two places. In the header of the units web page, under Alternate Formats, is a link to the MIB. A copy of the MIB is also included in the firmware zip file of version 2.53 and higher.
In a cabinet environment if the light level increases it may be an indication that a door has opened, meaning someone is entering the cabinet. In the worst case it may indicate a fire.
Sound level changes can indicate a number of things. For example, if sound levels drop off from the normal levels in a given space, it could indicate that one or more systems have shut down or perhaps that a fan has stopped. If levels increase, it may be due to conversation, work being performed, or a bad fan bearing.
Console Management Software can monitor and update up to 100 R-Series units at once. Simply download the latest firmware for each of your devices from http://www.geistmfg.com/GeistUS/Docs/downloads.htm and drop them into a folder on your hard drive. Point Console to the folder and select which units you wish to upgrade on the Console's Firmware page.
The webcam can be placed on any Ethernet segment that the R-Series can access. We have tested R-Series units in Nebraska with cameras in Texas with no issues.
The unit will display the voltage and current of each phase. Power can easily be balanced when you know how much power is on each phase.
Ethernet-enabled R-Series units contain an embedded microprocessor within the Ethernet jack that generates web pages.
There is no maximum amount of units that you can view. However, as more units are added the web page does take longer to generate. We recommend attaching no more than 100 units to Console Management Software. Console Software runs as a system service on the computer on which it is installed. If this service is not active, Console cannot monitor units.
This may be due to faulty sensor wiring, in which case the sensor will need to be replaced. Some customers with DC-powered units (RSE, RSMINI and RSMICRO) have found that grounding the chassis of the unit to an isolated ground point in their rack helps in this situation. The RSE and RSMINI163 contain a 10-32 threaded hole on the back of the unit which is used for ground purposes.
Check the camera IP address and camera model on the R-Series unit's Configuration page. If the camera model number and IP address are correct, you may need to update your camera to the latest firmware available from http://support.dlink.com.
It may be that someone has turned off the HTTP access and is only allowing HTTPS (secure) access. Try typing https:// into your browser to see if you can access the unit. If this works you can go into the configuration page and change from HTTPS only to HTTP and HTTPS access.Some users in enterprise environments have proxies enabled that can block access to R-Series devices. In Internet Explorer: - Go to Tools->Internet Options and click the Connections tab.
- Click ""LAN Settings"" at the bottom of the tab.
- If you have a proxy enabled, make sure that "bypass proxy server for local addresses" is selected. You may need to uncheck this to access other sites on your network once you are done using the R-Series.
You may need to undo these steps to access other sites on your network once you are done using the R-Series unit. If you are still experiencing difficulties, please contact Geist at 800-432-3219.
Your device may contain a defective microprocessor and will need to be returned to the factory for repair. Please contact your distributor to obtain return authorization.
The R-Series units are based on NET OS which requires both a carriage return (CR) and line feed (LF) character as line endings in telnet and FTP. UNIX and Linux typically only send the LF, omitting the CR by default. You will need to manually set your telnet and FTP clients to send CRLF to properly communicate with R-Series units. Some users have had success pressing Ctrl-Enter instead of Enter in Linux.
Remote sensors allow expansion of your monitoring capabilities for temperature, humidity, dew point and air flow in remote areas relative to the R-Series unit. Most R-Series units support up to 16 remote sensors (including Satellite Power units).
Yes. View-only access allows the user to see current log data which can be downloaded periodically to recreate the saved logs. Therefore the download log data is not restricted from this account.
No, however any alarms configured to use the buzzer will still trip and activate the buzzer while the Ethernet cord is unplugged. E-mail and SNMP alarms will not be sent while the Ethernet cable is unplugged.
No, this is a unitless measurement that can be used as a benchmark once an ideal condition is established. It can then be used to set low and high alarm trips that will send notification should a change in that condition occur.
R-Series units do not support motion detection directly. Many webcams, however, provide motion detection support and can be configured to send e-mails and/or activate dry contact switches that RacSense units can detect and react to.
No, this is a unitless (relative) measurement that can be used as a benchmark once an ideal condition is established. It can then be used to set low and high alarm trips that will send notification should a change in that value occur.
No, this is a unitless (relative) measurement that can be used as a benchmark once an ideal condition is established. It can then be used to set low and high alarm trips that will send notification should a change in that value occur.
The MIB is automatically updated on the unit as sensors are added or removed. The updated MIB may need to be reloaded into SNMP programs depending on the program used.
The 3 analog I/O ports, onboard environment and power sensors are included in the internal sensor readings and are not counted towards the maximum of 16. Each Satellite Power unit counts as one external sensor. Combination sensors, such as RTAF or RTHD, count as one sensor.
Yes. However, each sensor's name will be stored until it is cleared from the Display tab so that any custom names will not be lost.
We sell 5-port (SP-5) and 16-port (SPL16) splitter modules that can be used to increase the number of RJ-12 jacks. Alternatively, a common telephone splitter can be used. Make sure that the splitter is a straight-through 6-wire splitter and not a crossover or 4-wire splitter. If the wiring is reversed, none of the sensors will be discovered by the R-Series unit. A Satellite Power unit can also be used as a 3- port splitter, but it will be counted as one of your attached sensors.
Factory airflow calibration may not be viable for your steady state conditions. The airflow can be recalibrated via the Telnet command "airflowset." When recalibrating the sensor must be in a still air environment for proper calibration.
Most SNMP software requires that the appropriate MIB file be placed in a specified directory. This is done so that the SNMP software knows how to read the SNMP information available from the R-Series or Current Monitoring (EM) units. Some SNMP software (i.e. What's Up Gold) requires a program to be run to import the information in the MIB and make it useful.
This error is typically caused when the graphing routine cannot recognize or interpret a data point correctly. We are investigating the exact cause of this, but in the meantime there is a simple workaround: First, download your log data (only if you want to keep the data; otherwise, you can skip this step). Second, clear the unit's log history by going to the Logs page, checking the Clear Log History box, then press the button marked Save Changes. Your graphs should come back in a few minutes (the exact time will depend on your logging frequency setting) once the unit has accumulated sufficient new data to begin graphing again.
Most R-Series units have built in flash memory to store data that has been logged. When a network time server is available, date stamps are recorded with each data measurement. If the unit is powered down, no data is recorded, therefore it cannot be graphed. The break in the graph indicates this down-time. As soon as power is restored, monitoring and logging will continue as normal.
Your R-Series unit should have come with a plastic insertion tool. Insert the tool into the top edge of the top hole for the port you are trying to use. The upper edge of the metal tab in the lower hole will open, allowing you to insert a piece of wire. Remove the tool from the top hole and the metal tab will fall back into place and grip the wire. If your unit did not come with the insertion tool (or you have lost it), a small flathead screwdriver will usually suffice.
Confirm that the network card settings are correct for the camera IP address that you are trying to reach. Contact D-link for additional support.
The graph on the Logs page graphs only user selected variables. Select variables with similar values, then refresh the page with the time frame over which you would like to observe. Any number of devices may be selected, from one to all devices.
Currently supported models include: Axis - All
Panasonic - All
D-Link - DCS-900, DCS-910, DCS-950/G, DCS-2000, DCS-3220, DCS-3420, DCS-5300/G, DCS-6620
Linksys - WVC200
If you have a camera not listed here, please contact customer service at 800-432-3219 to see if it is compatible.
RCM and RCU units contain circuitry to detect whether the relay for each outlet has successfully switched to the desired state. "Relay Failure" shows up when the detected state of the relay does not match the state you have set.
The acronym means Root-Mean-Squared. It is used to indicate a calculated, highly accurate value versus an instantaneous estimate.
The unit is programmed to default to the US Military NTP servers at 192.5.41.40 and 192.5.41.41. These addresses are hard-coded into the unit and there is no need to re-enter them if they are overwritten. Simply clear out the text boxes and hit 'Save Changes.'
The R-Series unit circuit board power is parallel to the line. If the board malfunctions, the other equipment will still receive power.
Apparent Power is the calculation of Volts x Amps. Apparent power is measured in units of Volt-Amps (VA). Apparent power is used to measure the draw from a utility or for sizing wires and circuit breakers.
Power Factor is used to define the ratio of Real Power to Apparent Power, or how much of the power is being used to do work. Power Factor is therefore a number zero to one but may also be displayed as a percentage. Lower power factors have the additional cost of energy loss in the distribution system and require a larger infrastructure.
Real Power is sometimes referred to as ‘True’ power. Real Power is the actual power being used by the load and is measured in Watts (W). Real Power takes into account the phase angle of the current and this is typically the nameplate rating on IT equipment.
Time zone offset must be in military hours or - GMT. For instance, central time zone is -0600 or -0500 depending on daylight savings time. We suggest that time zones not be changed to reflect daylight savings time as data will either be overwritten or else a one hour break will occur - depending on which way the clocks change.
An RJ-11 is a 6 position phone type connector that uses 4 conductors. An RJ-12 is a 6 position phone type connector that uses 6 conductors. The R-Series products use all 6 conductors, so RJ-12 connectors are required. Splitters must also be 6-conductor or sensors will not be discovered by the R-Series unit.
Apparent power is the calculation of volts times amps. Real power is RMS power (real-time) plus the power factor calculation.
Switched (RCM-O) and Switched Ultra (RCU-O) both offer complete power monitoring and individual outlet switching. The RCM-O has circuit level monitoring. The RCU-O adds current monitoring of each individual outlet. The RCU-O also adds the "Max Group Amps" feature to limit outlets being turned on if the current has exceeded a set threshold.
The Remote Display (RSD) has been tested successfully at 1000 feet from the main R-Series unit. The maximum distance can vary based on conditions of the installation environment.
We have tested the Satellite Power Plus (RSS) successfully at 400 feet using Cat3 cable, however room conditions (including noise and cable quality) could affect the maximum distance.
The range for the temperature sensor is /- 0.5 degree from - 20 to 50 degrees Celsius.
The webcam image is scaled to 320x240 for display on the R-Series unit's Sensors page. Most webcams support higher resolutions than this via their built-in client software, but we limit the resolution to keep network traffic to a minimum. Click on the webcam image on the unit homepage to go directly to the camera's homepage.
The LED light on the RSD display will remain lit if any monitored device is in the alarm condition. Alarm notification is selected by the user on the Alarms page. The LED is activated in conjunction with the buzzer reporting function.
NTP servers run on TCP port 123.
The devices attached to these jacks use the Dallas 1-wire signaling protocol. The sensors are custom made to interface with R-Series devices. Each sensor has a built-in 64 bit unique address and can be run hundreds of feet. Use of non-Geist 1-wire sensors may void your warranty.
10/100Mbps auto-sensing.
These units are powered through a 2.1mm power jack. The power requirements are 6Vdc, 300ma per unit. Actual consumption is usually less, but, due to changes in consumption based on attached accessories as well as fluctuations due to processing, we recommend dedicating 300ma per unit.
At this time the R-Series devices are not capable of outputting a signal on the I/O ports. The I/O ports are capable of receiving a signal from a normally open/normally closed sensor, but are not capable of sending information out.
Confirm that after you download the firmware you unzip all of the included files and run the updater from that folder. The updater utilizes other files in the zip file, so you must extract all files for it to work.
No, you will only need a splitter if multiple sensors are being used.
For firmware versions 2.53 or higher there is a CSV file, in the zip file, that contains the list of OID's for the unit.
Data is stored in an internal flash RAM. Every time the device polls for new sensor data, all previously stored data (available on the Logs page) is saved in the flash along with the most recent data. In the event of a power failure, all data up until the last reading will be saved. Keep in mind that due to space limitations, typically only a few days' worth of information is available from the device itself. Data can be exported to an CSV file or read directly via the XML link at the top of the device's web page.
DHCP, HTML, HTTP(S), ICMP, SNMP, SMTP, TCP/IP, Telnet, UDP and XML.
Only the values checked on the Logs page will be shown on the scrolling display.
These units contain no high voltage parts and therefore do not require UL Listing. The wall transformer that breaks the high voltage down to low voltage (<12V DC) is UL Listed.
Most IT personnel have a Cat3 crimper and a box of RJ-12 connectors. This is the lowest cost, easiest-to-use connection method, making it a convenient choice. Cat5 or Cat6 cable can be used for extensions as well as long as RJ-12s are crimped onto the ends.
This can be due to a variety of factors: The small size and relatively low airflow within the chassis causes temperatures inside it to rise slightly. On some PCBs, the temperature sensor is placed near the main microprocessor, causing a small heat rise. Heat from the microprocessor also transfers back into the PCB and can raise the overall temperature of the device. Heat from other devices in the rack often transfers through the rack's metal structure and into the chassis of the climate monitor. One can easily verify the accuracy of the internal temperature sensor by placing a remote temperature sensor in contact with the unit's chassis and waiting a few moments for the temperature of the sensor to equalize with the chassis. Since this situation depends heavily on the specifics of the rack the unit is installed in, we have decided not to correct the reading by default. However, we do provide a user-configurable offset of up to 7 degrees (in the currently selected temperature unit) on the unit’s Display page.
The units may be programmed to send SNMP traps which can be used by console monitoring software (What's Up Gold, HP OpenView, etc.) to alarm in any number of fashions, including pages, phone calls, on-screen alarms, etc.
R-Series Version 2.xx units communicate at either 10Mb/s or 100 Mb/s and therefore should have no trouble working with a 10/100/1000 switch.
R-Series Version 2.xx units communicate at either 10Mb/s or 100 Mb/s and therefore are not compatible with a 1000/1000 switch. A suggestion would be to add a 10/100/1000 switch to connect R-Series units to the network.
R-Series Version 3.xx units communicate at 10Mb/s and therefore should have no trouble working with a 10/100/1000 switch.
R-Series Version 3.xx units communicate at 10Mb/s and therefore are not compatible with a 1000/10000 switch. A suggestion would be to add a 10/100/1000 switch to connect R-Series units to the network.
The units may be programmed to send e-mails or SNMP traps which can be used by console monitoring software (What's Up Gold, HP OpenView, etc.) to alarm in any number of fashions, including pages, phone calls, on-screen alarms, etc. Some units either include or are available with optional audible alarms.
No, you should set your trip points at the level you wish to be notified. If you are more comfortable at 60 or 70% of capacity, your trip points should reflect this.
R-Series Firmware Versions 2.xx & 3.xx
Units that contain the Version 2.xx cannot be updated to Version 3.xx, because it is a physical hardware platform change and not a software only change.
You will have to load both MIBs into the SNMP software if you are utilizing both Version 2.xx and Version 3.xx units.
Yes with RSCS-3.
Please contact support, at 800-432-3219, for assistance in obtaining a temporary replacement password.
- Version 2.xx has one green and one amber LED on the Ethernet jack
- Version 3.xx has two green LEDs on the Ethernet jack
- Version 3.xx contains a reset button under the Ethernet jack
- Version 3.xx also features the Geist name on the front of the unit
The box label contains a MAC/Firmware Version number.
The default IP of 192.168.123.123 is always available. You can connect a PC or laptop to your RacSense device directly by using a crossover cable. You will then need to configure the IP of the network adapter to 192.168.123.1 with no gateway. Once this is done you can point your web browser to http://192.168.123.123 or https://192.168.123.123 (if you have HTTPS enabled) and the web interface should load. From there you can retrieve the configured IP information from the configuration page.
Intelligent or Managed Switches may have an issue with the switch detecting multiple instances of the 192.168.123.123 IP address. Start your troubleshooting by checking your switch to see if IP conflicts have occurred and if this is the case, you will need to contact the switch manufacturer for support on configuring the switch to ignore the 192.168.123.123 IP address. Detection of the default IP addresses as a duplicate IP address is eliminated in Version 3.xx units. Once you change the unit IP address on initial set-up the default IP (back door) address becomes disabled and the switch will not be able to communicate with the unit by any means using the default IP. Version 3.xx units feature a reset button that allows the user to reset the IP address back to the default.

Telnet is supported on RacSense Version 2.XX and 3.XX devices. Telnet is not supported by Ethernet Meter units. To access units via Telnet, use the Administrator level username/password. Available commands and information vary by unit type. Enter "help" after logging in to see available commands. On RacSense Version 2.XX devices, "report" will provide an easy to read status report. On RacSense Version 3.XX devices, "sensors" will provide a similar report.
The webpage visual differences of Version 3.xx are: - Thinner graphs lines
- Multiple choices for how the customer can view their webpages
- The default view is arranged slightly different. The Classic view will remain on the top of the screen
- The default view navigation bar will be on the left, and the Classic view will remain on the top of the screen
- The menu order has changed to list the most frequently used links to the top (or left, depending on layout version)

Syslog is a standard for forwarding log messages in an IP network.
The amount of data that can be saved depends on the number of devices attached and the frequency of logging that has been selected by the user. The time frame of data that can be saved locally is listed on the Logs page.
Logging frequency is user defined on the Logs page. RacSense units save log data on a set interval, determined by the logging frequency. The default frequency is every 60 seconds, however this can be changed to between 15 and 250 seconds. A lower frequency saves data more often, however memory will fill faster and limit the number of days of data stored. The text under the graph, gives the number days that can be logged at the current logging frequency. The data log is a circular buffer, once it fills up, old data is overwritten by the newer data.
You will be provided with an error message denying the update.
You will be provided with an error message denying the update.
Due to the way the RacSense units keep time when they are not able to reach a network time server, upon contact with a time server log data will be cleared. If you wish to save the log data, hook the unit up to a computer via a crossover cable and extract the logs before plugging the unit into your network.
The Diagnostic page syslog is used to send information to a syslog daemon (server) on the network. The Event Log page can be used to send an email to support at Geist to assist in troubleshooting errors.
Geist is changing to Version 3.xx in order to make it simpler to update unit firmware and respond to our customers' software needs in a more timely manner.
Yes.
RacSense Version 2.xx units communicate at either 10Mb/s or 100 Mb/s and therefore should have no trouble working with a 10/100/1000 switch.
RacSense Version 2.xx units communicate at either 10Mb/s or 100 Mb/s and therefore are not compatible with a 1000/1000 switch. A suggestion would be to add a 10/100/1000 switch to connect RacSense units to the network.

Sensors & AccessoriesThe problem is most likely that one of your external sensors has a crossed wire. Follow this procedure to test the sensors: - Unplug all of the sensors and check the ""Remove all unplugged devices"" check box on the Display page.
- Plug in one sensor and wait for it to be detected.
- If the sensor works, leave it plugged in and plug in another sensor.
- If the sensors stop responding, the last sensor to be plugged in is faulty. If your unit is under warranty, call support for a replacement.
Yes, they will appear on the site shortly after being connected.
The test alarms function can be used to turn the buzzer off remotely. The following steps will lead you through this process. - Go to the Alarms page.
- Scroll down to the Test Alarms section.
- Pick one of the internal sensors from the Sensors drop-down box.
- From the Alarm State drop-down, choose Buzzer.
- Select Clear from the Trap Type drop-down.
- Click on the Test button.
- The buzzer should turn off in a few seconds.
Temperature sensors are factory calibrated by the IC manufacturer and should maintain accuracy of /- 0.5 degrees Celsius for the better part of a decade. Remote airflow sensors are calibrated at Geist but, due to the nature of the sensor, may need to be calibrated by the end-user for more consistent readings.
Yes
No, the RSE contains a built-in display.
Use the following formula to calculate the actual voltage. (- 0.72 x Displayed Value). For example, a reading of 60 would correspond to approximately -43.2 Vdc If you can connect this sensor to a CCAT unit that is programmed for -48Vdc operation, the RacSense will perform the conversion automatically.
There is no maximum amount of units that you can view. However, as more units are added the web page does take longer to generate. We recommend attaching no more than 100 units to Console software. Console software runs as a system service on the computer on which it is installed. If this service is not active, Console cannot monitor units.
Check the camera IP address and camera model on the RacSense unit's Configuration page. If the camera model number and IP address are correct, you may need to update your camera to the latest firmware available from http://support.dlink.com.
You need to install ffdshow from the installation CD that came with the camera. Make sure to do a full install as this will include the required codec.
RacSense units do not support motion detection directly. Many webcams, however, provide motion detection support and can be configured to send e-mails and/or activate dry contact switches that RacSense units can detect and react to.
It is not possible to store webcam images from the RacSense unit's homepage. In most cases this is possible through the camera's internal web interface.
Yes. However, each sensor's name will be stored until it is cleared from the Display tab so that any custom names will not be lost.
We sell 5-port (SP-5) and 16-port (SPL16) splitter modules that can be used to increase the number of RJ-12 jacks. Alternatively, a common telephone splitter can be used. Make sure that the splitter is a straight-through 6-wire splitter and not a crossover or 4-wire splitter. If the wiring is reversed, none of the sensors will be discovered by the RacSense unit. An RSS unit can also be used as a 3- port splitter, but it will be counted as one of your attached sensors.
Confirm that the network card settings are correct for the camera IP address that you are trying to reach. Contact D-link for additional support.
Console requires:
Microsoft Windows 2000/2003/XP with the latest service pack
Microsoft .Net Framework 1.0 or higher
Intel Pentium 3 1GHz or AMD Athlon 1GHz or faster processor
512MB RAM
50MB of hard drive space for installation
4 GB of hard drive space for log storage
10Mbps network connection or faster
An RJ-11 is a 6 position phone type connector that uses 4 conductors. An RJ-12 is a 6 position phone type connector that uses 6 conductors. The RacSense products use all 6 conductors, so RJ-12 connectors are required. Splitters must also be 6-conductor or sensors will not be discovered by the RacSense unit.
This varies by camera and power frequency. In the US, most cameras run up to 30fps. In Europe and other locations with 50Hz power, they may be limited to 25fps.
The RSD has been tested successfully at 1000 feet from the main RacSense unit. The maximum distance can vary based on conditions of the installation environment.
Temperature sensors have been tested successfully at up to 600 feet.
The range for the temperature sensor is /- 0.5 degree from - 20 to 50 degrees Celsius.
The LED light on the RSD display will remain lit if any monitored device is in the alarm condition. Alarm notification is selected by the user on the Alarms page. The LED is activated in conjunction with the buzzer reporting function.
The devices attached to these jacks use the Dallas 1-wire signaling protocol. The sensors are custom made to interface with RacSense devices. Each sensor has a built-in 64 bit unique address and can be run hundreds of feet. Use of non-Geist 1-wire sensors may void your warranty.
Most IT personnel have a Cat3 crimper and a box of RJ-12 connectors. This is the lowest cost, easiest-to-use connection method, making it a convenient choice. Cat5 or Cat6 cable can be used for extensions as well as long as RJ- 12s are crimped onto the ends.
An ActiveX application is required to access some D-Link cameras. This means these cameras will only work with Internet Explorer 6.x and higher on Windows. If you are asked by the browser to install a viewer application, do so. Axis network cameras do not require ActiveX and may work better for you if you are not able to run Internet Explorer.
This can be due to a variety of factors:
The small size and relatively low airflow within the chassis causes temperatures inside it to rise slightly.
On some PCBs, the temperature sensor is placed near the main microprocessor, causing a small heat rise.
Heat from the microprocessor also transfers back into the PCB and can raise the overall temperature of the device.
Heat from other devices in the rack often transfers through the rack's metal structure and into the chassis of the climate monitor.
One can easily verify the accuracy of the internal temperature sensor by placing a remote temperature sensor in contact with the unit's chassis and waiting a few moments for the temperature of the sensor to equalize with the chassis.
Since this situation depends heavily on the specifics of the rack the unit is installed in, we have decided not to correct the reading by default. However, we do provide a user-configurable offset of up to 7 degrees (in the currently selected temperature unit) on the unit’s Display page.
