Sensors
Hardware sensors or probes help you to monitor the systems on your network 
in a more efficient way by enabling you to take appropriate actions to prevent 
disasters, such as system instability or damage.
You can use the DRAC 5 to monitor hardware sensor for batteries, fan 
probes, chassis intrusion, power supplies, power consumed, temperature, 
and voltages.
Battery Probes
The Battery probes provide information about the system board CMOS and 
storage RAM on motherboard (ROMB) batteries.
 NOTE: The Storage ROMB battery settings are available only if the system has 
a ROMB.
Fan Probes
The fan probe sensor provides information on:
• fan redundancy — the ability of the secondary fan to replace the primary 
fan if the primary fan fails to dissipate heat at a pre-set speed.
• fan probe list — provides information on the fan speed for all fans in the 
system.
Chassis Intrusion Probes
The chassis intrusion probes provides status of the chassis, whether chassis is 
open or closed. 
						

							292Sensors
Power Supplies Probes
The power supplies probes provides information on:
• status of the power supplies, whether within the normal threshold value or 
has crossed threshold value.
 NOTE: You can set threshold values only from the Dell OpenManage Server 
Administrator. See the Dell OpenManage Server Administrator User’s Guide 
for more information.
• power supply redundancy, that is, the ability of the redundant power 
supply to replace the primary power supply if the primary power supply 
fails.
 NOTE: If there is only one power supply in the system, the Power Supply 
Redundancy section will not display.
Hardware Performance Probes
The hardware performance sensor provides status of the performance of your 
central processing unit (CPU), whether degraded or normal. The status of the 
hardware performance sensors is degraded when the CPU is in throttled state.
Power Monitoring Probes
Power monitoring provides information about the real time consumption of 
power, in watts and amperes. This information is provided to the DRAC 5 
through the baseboard management controller (BMC) firmware sensors.
 NOTE: This feature is supported only on limited Dell PowerEdge x9xx and xx0x 
systems.
DRAC 5 provides advanced power monitoring features. This includes:
• Graphical representation of the system power level in Watts and power 
supplies in Amperes over a time period.
• Maximum, minimum, and average power consumption statistics for the 
system in Watts and BTU/Hr (British Thermal Unit per Hour) over the 
last 1 hour, 1 day, and 1 week from the current DRAC time as a graph.
• Power consumed by the system in Watts and the average current 
consumed by each power supply in Amperes. 
						

							Sensors293
Graph Information
The Graph Information page displays the graphs for the system power level 
in Watts and power supplies in Amperes over a time period. The page auto 
refreshes every minute.
 NOTE: The data is obtained by the DRAC 5 every five minutes and is lost after a 
DRAC reset, AC power cycle, or a firmware update.
 
NOTE: The graphs may display gaps either when the system is powered down or 
when the BMC resets. This is because the power sensors are unavailable during 
this period.
Power Consumption in Watts displays the time period over which the data 
for power is collected. You can set the X-axis range to 1 hour, 1 day, or 1 week 
from the drop-down menu available on this page. The time period is from the 
current time set on the DRAC. The Y-axis displays the power consumed by 
the system in Watts.
Power Consumption in Amperes displays the time period over which the data 
for current is collected. You can set the X-axis range to 1 hour, 1 day, or 1 
week from the drop-down menu available on this page. The time period is 
from the current DRAC time. The Y-axis displays the current consumed by 
the power supplies in Amperes. If there are more than one power supply units 
on the system and if the readings are the same, the current graphs may 
overlap each other.
Power Consumption Information 
The Power Consumption Information page displays the power consumed by 
the system in Watts and the average current consumed by each power supply 
in Amperes.
This page also displays the status of the probes, probe name, power 
consumed, the minimum and maximum thresholds at which warning and 
failure alerts are generated, location of the power supply unit, and the average 
current consumed by each power supply in Amperes. 
						

							294Sensors
Power Statistics
The Power Statistics page displays the average power consumption and the 
maximum and the minimum power consumption statistics for the system in 
Watts and BTU/Hr (British Thermal Unit per Hour) over the last 1 hour, 
1 day, or 1 week from the current DRAC time. The data is obtained by the 
DRAC 5 and is reset if the DRAC undergoes a reset for any reason.
Temperature Probes
The temperature sensor provides information about the system board 
ambient temperature. The temperature probes indicate whether the status of 
the probes is within the pre-set warning and critical threshold value.
Voltage Probes
The following are typical voltage probes. Your system may have these and/or 
others present. 
• CPU [n] VCORE 
• System Board 0.9V PG 
• System Board 1.5V ESB2 PG 
• System Board 1.5V PG 
• System Board 1.8V PG 
• System Board 3.3V PG 
• System Board 5V PG 
• System Board Backplane PG 
• System Board CPU VTT 
• System Board Linear PG
The voltage probes indicate whether the status of the probes is within the 
pre-set warning and critical threshold values.
