ALM-0x00000007 CPU VRD Overtemperature (CPU, Minor Alarm)
Description
Alarm message:
The CPU arg1 VRD temperature (arg2 degrees C) exceeds the overtemperature threshold (arg3 degrees C) (SN: arg4, BN: arg5).
From iBMC V316, the CPU and disk alarms will also include the SN and BOM code and the mainboard and memory alarms will also include the BOM code.
This alarm is generated when the VDQ temperature of a CPU exceeds the overtemperature minor threshold. This alarm is cleared when the temperature is within the normal range.
Alarm object: CPU
Parameters
| Name | Meaning |
|---|---|
arg1 |
Socket No. of the CPU. |
arg2 |
Current reading of the sensor. |
arg3 |
Alarm threshold. |
arg4 |
CPU serial number. |
arg5 |
BOM code. |
Possible Causes
- A fan module is faulty.
- The equipment room temperature exceeds the normal range.
- The air inlet or outlet is blocked.
- The air duct is not installed.
- The mainboard is faulty.
Procedure
- Check whether there are fan module alarms.
- Replace the fan module. After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 3.
- Check whether the equipment room temperature exceeds the normal range.
- Reduce the equipment room temperature to the normal range. After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 5.
- Check whether the air inlet or outlet of the server is blocked.
- Clear the blockage. After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 7.
- Check whether the server is installed with an air duct.
- Install an air duct. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 9.
- Replace the mainboard. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 10.
