Displaying the Temperature

Displaying the Temperature

Context

If the device temperature is too high or too low, the hardware may be damaged. To learn about the current device temperature, use the following command.

Procedure

  • Run the display temperature { all | slot slot-id } command to view the device temperature.

FAQ

How Can I Determine Whether the Card Temperature Is too High?

Generally, the recommended operating temperature of a card is from 0°C to 45°C.

The card temperature is too high if high temperature alarm is generated on the card. The system adjusts the fan speed automatically to help ensure that the card temperature is within the normal range.

The following is an example of high temperature alarms:
ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.10.13 hwBrdTempAlarm 140544 
ENTITYTRAP/1/ENTITYBRDTEMPALARM: OID [oid] Temperature rise over or fall below the warning alarm threshold.(Index=[INTEGER], 
ThresholdEntityPhysicalIndex=[INTEGER],EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityThresholdType=[INTEGER],
EntityThresholdValue=[INTEGER],EntityThresholdCurrent=[INTEGER], EntityTrapFaultID=[INTEGER])
BASETRAP_1.3.6.1.4.1.2011.5.25.129.2.2.1 hwTempRisingAlarm 
BASETRAP/1/TEMRISING: OID [oid] Temperature exceeded the upper pr e-alarm limit.(Index=[INTEGER], BaseThresholdPhyIndex=[INT
EGER], ThresholdType=[ INTEGER], ThresholdIndex=[INTEGER], Severity=[INTEGER], ProbableCause=[INTEGER], EventType=[INTEGER], 
PhysicalName="[OCTET]", ThresholdValue=[INTEGER], Threshol dUnit=[INTEGER], ThresholdHighWarning=[INTEGER], ThresholdHighCrit
ical=[INTEGER] )

Why Is a High Temperature Alarm Generated and How Can I Clear It?

Possible Causes
  • Air ventilation around the device is insufficient or obstructed.

  • The air filter is blocked.

  • Vacant slots are not covered with filler panels.

  • The ambient temperature of the device is too high.

  • The number of fans on the device is insufficient.

  • A fan on the device is faulty.

  • The chip temperature is too high.

Troubleshooting Procedure
  1. Clean the air filter and remove the objects that block the air exhaust area (if any). Cover all vacant slots with filler panels to ensure efficient heat dissipation. Then check whether the alarm is cleared.

    If the fault persists, go to step 2.

  2. Check whether the air filter is blocked.

    Clean the air filter and remove any objects that obstruct the intake and exhaust vents.

    If the fault persists, go to step 3.

  3. Check whether all vacant slots are covered with filler panels.

    Ensure that all vacant slots are covered with filler panels.

    If the fault persists, go to step 4.

  4. Check whether the ambient temperature of the device is too high.

    If the ambient temperature is too high, take appropriate measures to lower the temperature.

    If the fault persists, go to step 5.

  5. Check whether fans are installed in the fan slots.

    Add more fans if fan slots are available.

    If the fault persists, go to step 6.

  6. Check whether a fan is faulty.

    Run the display fan command to check the status of fans and replace any faulty fans.

    If the fault persists, go to step 7.

  7. Check the chip temperature of cards.

    Run the display temperature all command to view the chip temperature of each card on the device and take appropriate measures if required.

    If the fault persists, go to step 8.

  8. Collect the following information and contact Huawei technical support:

    • Results of the preceding troubleshooting procedure
    • Configuration file, logs, and alarms of the device
Determining Whether a High Temperature Alarm Is Cleared
  1. This alarm is not displayed on the NMS.
  2. This alarm is not displayed when you run the display trapbuffer command to view the trap buffer.
  3. This alarm is not displayed when you run the terminal monitor and terminal trapping commands to view alarm information.
