SRM/4/LSWTEMP_ALARM

Message

SRM/4/LSWTEMP_ALARM: The [STRING1] temperature of [STRING2] exceeds the upper limit. This problem may be caused by poor ventilation, blocked air filter, or fan failure. (Value=[ULONG1], UpperThreshold=[ULONG2], LowerThreshold=[ULONG3])

Description

The temperature sensor detects that the temperature exceeds the upper limit. This problem may be caused by poor ventilation, blocked air filter, or fan failure.

Parameters

Parameter Name	Parameter Meaning
STRING1	Indicates the name of temperature sensor.
STRING2	Indicates the slot ID.
Value	Indicates the current temperature.
UpperThreshold	Indicates the upper limit of temperature.
LowerThreshold	Indicates the lower limit of temperature.

Possible Causes

The hot air in the equipment cannot be exhausted.
The air filter is blocked.
A fan on the device is faulty.

Procedure

Clean the air filter and remove the objects that block the air exhaust area (if any) to ensure efficient heat dissipation. Then check whether the log persists.
- If so, go to step 2.
- If not, the fault has been rectified.
Check whether the ambient temperature is too high.
- If so, install an external cooling device to reduce the environment temperature.
- If not, go to step 3.
Check whether any fan on the device is faulty. Rectify the fault according to "A Fan Fails" in the Troubleshooting Insights - Campus Switch - Hardware Fault.
- If so, replace the faulty fan.
- If not, go to step 4.
Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
