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.
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.
You can also view a graphical representation of the consumption of power for the last one hour, day, or week from the current time set in the DRAC.
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.
