Number of fans in the fan tray.



Operating status of each fan.



Fan speed.

Verify that the air inlet and outlet vents of the chassis are not blocked. If they are blocked, clean
them to keep good ventilation.

Remove and reinstall the fan tray and fasten the screws tightly to make sure it is installed
securely in the slot.

Verify that the empty service slots and power supply slots are installed with filler panels. Install
filler panels in empty slots.

Replace the fan tray.

If the issue persists, contact H3C Support.

MPU failure

Symptom

The RUN LED for the MPU is off.

Solution

To resolve the issue:

Verify that the power system is operating correctly. For more information, see "

Power supply

failure

Remove and reinstall the MPU to make sure it is installed securely. For more information, see
"Installing MPUs."

Press the

RESET

button on the MPU to reset the MPU. After the MPU is reset, verify that the

RUN LED is on.

If the router has empty MPU slots, install the MPU in the empty MPU slot, and verify that the
MPU can operate correctly.

If the issue persists, contact H3C Support.

NOTE:

The module slot numbers are marked on the ejector lever pillow blocks at the slot edges.

Fabric module failure

Symptom

The RUN LED on the fabric module is off or steady red.

Solution

To resolve the issue:

Verify that the MPU is operating correctly. For more information, see "

Verify that the fabric module is compatible with the system software. Upgrade the system
software if it does not support the fabric module.

Calculate the total power consumption, and make sure your power supplies can provide
enough power. For more information, see
