Power module failure
When a power module is operating correctly, its input and output LEDs are steady green. When its
input or output LED is red, the power module is faulty.
To troubleshoot the power module:
1.
Verify that the power module model is as required. For more information about power modules
available for the switch, see "
Appendix B FRUs and compatibility matrixes ."
2.
Verify that the power cable is connected correctly. You can remove and reconnect the power
cable to make sure the power cable is connected correctly.
3.
Replace the power cable.
4.
Verify that the power module is fully seated in the slot. For more information, see " Installing a
power module ."
5.
Verify that the power source is supplying power at the correct voltage.
6.
Verify that the power module does not have problems such as output short-circuit, output
over-current, output over-voltage, input under-voltage, or over temperature.
7.
Install the power module to another empty power module slot. If the power module can operate
correctly, the previous power module slot is faulty. If the power module cannot operate correctly,
go to the next step.
8.
Install a correctly-operating power module of the same model into the same slot, and connect it
to the same power input end. If the new power module can operate correctly, the old power
module has failed. Contact your sales agent or local service engineer to replace the old power
module.
9.
If the problem persists, contact H3C Support.
Fan tray failure
When a fan tray is operating correctly, the FAN LED is green. If the FAN LED is not green, the fan
tray is faulty.
To troubleshoot the fan tray:
1.
Verify that the power system is operating correctly. For more information, see " Power module
failure ."
2.
Verify that the air inlet and air outlet vents of the chassis are not blocked. If they are blocked,
clean them to keep good ventilation.
3.
Remove and re-install the fan tray to make sure it is fully seated in the slot.
4.
Verify that the empty LPU slots and power module slots are installed with filler panels. Install
filler panels to empty slots to guarantee good ventilation.
5.
Replace the fan tray.
6.
If the problem persists, contact H3C Support.
