Displaying the Temperature

Displaying the Temperature


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.


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


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

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

For details about the device operating temperature , see "Specifications" in the Hardware Description - Chassis.

The following is an example of high temperature alarms:

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 ambient temperature of the device is too high.

  • A fan on the device is faulty.

  • The chip temperature is too high.

Troubleshooting Procedure
  1. Clean the air vent and check whether the alarm is cleared.

    (1) If so, go to step 7.

    (2) If not, go to step 2.

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

    (1) If so, go to step 3.

    (2) If not, go to step 4.

  3. Lower the temperature in the equipment room, and then go to step 4.

  4. Run the display fan command to check whether any fan is faulty according to the status of fans.

    (1) If so, go to step 6

    (2) If not, go to step 5.

  5. Replace the faulty fan, and then go to step 8.
  6. Run the display temperature all command to view the temperature of he device. Check whether the temperature is high.

    (1) If so, go to step 6.

    (2) If not, go to step 7.

  7. Contact technical support personnel.
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.
