Operating Power Module Failure (For Switch Models That Support Removable Power Modules); Symptom; Solution - H3C S5150-EI Series Troubleshooting Manual

If you can access the CLI, execute the display diagnostic-information command to
collect operating statistics.
If you cannot access the CLI, go to step 2.
2. Verify that the system software image on the switch is correct.
Log in to the switch through the console port and restart the switch. If the system reports that a
CRC error has occurred or that no system software image is available during the BootWare
loading process, reload the system software image on the BootWare menu and configure it as
the current system software image.
3. If the problem persists, contact H3C Support.
Operating power module failure (for switch
models that support removable power modules)

Symptom

A trap or log is generated indicating that an operating power module is faulty.

Solution

To resolve the problem:
1. Execute the display power command to display power module information.
<Sysname> display power
Slot 1:
PowerID State
1
2
If the power module is in Absent state, go to step 2. If the power module is in Fault state, go to
step 3.
2. Remove and reinstall the power module to make sure the power module is installed correctly.
Then, execute the display power command to verify that the power module has changed to
Normal state. If the power module remains in Absent state, replace the power module.
3. When the power module is in Fault state, perform the following tasks:
a. Verify that the power module has not been disconnected from the power source. If it has
been disconnected from the power source, connect the power source to it.
b. Verify that the power module surface is clean. If there is dust accumulated on the power
module, remove the dust. Then remove and reinstall the power module. Execute the
display power command to verify that the power module has changed to Normal state. If
the power module remains in Fault state, go to step c.
c. Install the power module into an empty power module slot. Then execute the display power
command to verify that the power module has changed to Normal state in the new slot. If
the power module remains in Fault state, replace the power module.
4. If the problem persists, contact H3C Support.
