Switch Hardware Problems

The following table lists situations that might occur with switch hardware and corrective steps that can be taken to resolve the problem.

Situation
Corrective Steps
The Attention LED on a power supply is lit or the power supply seems dysfunctional.
  1. Check the power supply status.

    See Display Power Supply Status.

  2. Unplug the respective power cord, wait 15 minutes, then reattach the power cord.

  3. If the previous steps do not rectify the situation, replace the power supply.

    See Servicing the Power Supplies.
There is no network communication with the management controller.
  1. Verify that the management controller is powered without faults.

    See Check Chassis Status LEDs .

  2. Verify that there is a LinkUp condition at the network management port.

    See Check Network Management Port Status LEDs.

  3. Verfiy the DHCP server is providing the IP address you are using to access the management controller.

    See DHCP server documentation.

  4. If you are able to access the management controller through the USB connector, restart the management controller.

    See Access the Management Controller From the USB Management Port and Restart the Management Controller.

  5. If you are unable to access the management controller through the USB connector, power cycle the switch.

    See Power Off a Power Supply and Power On a Power Supply.

  6. If the previous steps do not rectify the situation, replace the switch.

    See Remove the Switch From the Rack and Installing the Switch.
The Attention LED on the switch chassis is lit or the management controller seems dysfunctional.
  1. If you are unable to access the management controller, power cycle the switch.

    See Power Off a Power Supply and Power On a Power Supply.

  2. If you are able to access the management controller, restart the management controller.

    See Restart the Management Controller.

  3. Check overall switch health.

    See Display Switch General Health

  4. Verify that the switch is within operating temperatures and voltages.

    See Display Switch Environmental and Operational Data.

  5. If the previous steps do not rectify the situation, replace the switch.

    See Remove the Switch From the Rack and Installing the Switch.
The Attention LED on a fan is lit or the fan seems dysfunctional.
  1. Check the fan speed.
