ALM-3276800001 Indicates that temperature exceeded the upper pre-alarm limit

Description

SRM/3/TEMPRISINGALARM: OID [OID] temperature over high threshold .(EntityPhysicalIndex=[INTEGER1], BaseThresholdEntry_entPhysicalIndex=[INTEGER2], BaseThresholdEntry_hwBaseThresholdType=[INTEGER3], BaseThresholdEntry_hwBaseThresholdIndex=[INTEGER4], BaseTrapSeverity=[INTEGER5], BaseTrapProbableCause=[INTEGER6], BaseTrapEventType=[INTEGER7], EntPhysicalName=[OCTET], BaseThresholdValue=[INTEGER8], BaseThresholdUnit=[INTEGER9], BaseThresholdHighWarning=[INTEGER10], BaseThresholdHighCritical=[INTEGER11])

The temperature exceeded the upper threshold.

Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800001	Minor	Equipment alarm

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
EntityPhysicalIndex	Entity index.
BaseThresholdEntry_entPhysicalIndex	Index of the entity causing this temperature alarm.
BaseThresholdEntry_hwBaseThresholdType	Type of the detected entity (The value 1 indicates the temperature sensor of a certain type that is adopted by the S-switch.)
BaseThresholdEntry_hwBaseThresholdIndex	Index of the temperature sensor (The value begins from 1.)
BaseTrapSeverity	Severity code.
BaseTrapProbableCause	Error code.
BaseTrapEventType	Code of the event type.
EntPhysicalName	Entity name.
BaseThresholdValue	Current temperature.
BaseThresholdUnit	Unit of the temperature.
BaseThresholdLowWarning	Upper threshold of the temperature.
BaseThresholdLowWarning	Major upper threshold of the temperature.

Impact on the System

When the temperature exceeds the upper threshold, the switch may not work properly and packet loss may occur. Or more seriously, the system may not respond or reset abnormally.

Possible Causes

The chassis is not ventilated well, which causes heat unable to be dissipated.
The ambient temperature is high.
There are not enough fans in the switch.
One or more fans in the switch have failed.
The upper threshold of the temperature is too low.

Procedure

Clean the air vents and check whether the alarm is cleared.

(1) If so, go to step 13.

(2) If not, go to step 2.
Check whether the ambient temperature is high.

(1) If so, go to step 3.

(2) If not, go to step 4.
Lower the temperature in the equipment room, and then go to step 4.
Check whether all the fans are present and working normally.

(1) If so, go to step 6.

(2) If not, go to step 5.
Install more fans in the switch, and then go to step 6.
Run the display fan command to check the status of fans and determine whether any fan is faulty.

(1) If so, go to step 7.

(2) If not, go to step 8.
Replace the faulty fan, and then go to step 8.
After the switch has been running for a period of time, run the display temperature all command to check whether temperature of the switch is still high.

(1) If so, go to step 9.

(2) If not, go to step 13.
Check whether the upper threshold of the temperature is too low.

(1) If so, go to step 10.

(2) If not, go to step 12.
Run the temperature threshold slot slotid lower-limit lower upper-limit upper command to set a higher upper threshold of the temperature.
After the switch has been running for a period of time, run the display temperature all command to check whether temperature of the switch is still high.

(1) If so, go to step 12.

(2) If not, go to step 13.
