Fixed power module failure

The S5560X-30F-EIF, S5560X-34S-EI, and S5560X-54S-EI switches use fixed power modules and
support AC power input, DC power input, and concurrent AC and DC power inputs.

AC input failure

Symptom
The switch uses only AC power input. The system status LED is off.
Solution
To resolve the issue:
1. Verify that the AC power cord connects the switch to an AC power source correctly, and the AC
power receptacle on the switch and the AC power outlet are in good condition.
2. Verify that the AC power source is operating correctly.
3. Verify that the ambient temperature of the switch is in the acceptable range and ensure good
ventilation for the power module. Overtemperature can cause the power module to stop
working and enter the protection state.
4. If the issue persists, contact H3C Support.

DC input failure

Symptom
The switch uses only DC power input. The system status LED is off.
