Ac And Dc Concurrent Input Failure - H3C S5560X-30C-EI Installation Manual

Solution
To resolve the issue:
1. Verify that the switch is connected correctly to the DC power source.
2. Verify that the DC 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.

AC and DC concurrent input failure

Symptom 1
The switch uses concurrent AC and DC power inputs. The system status LED is off.
Solution
To resolve the issue:
1. Verify that the AC power cord connects the switch to the power source correctly, and the
AC-input 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 switch is connected correctly to the DC power source.
4. Verify that the DC power source is operating correctly.
5. 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.
6. If the issue persists, contact H3C Support.
Symptom 2
•
On an S5560X-30F-EIF switch that uses concurrent AC and DC power inputs, the system
status LED is on, the DC PWR LED is steady green, but the AC PWR LED is off.
•
On an S5560X-34S-EI or S5560X-54S-EI switch that uses concurrent AC and DC power inputs,
the system status LED is on but the RPS status LED is steady yellow.
Solution
To resolve the issue:
1. Verify that the AC power cord is securely connected to the switch, and the AC-input power
receptacle on the switch and the connected 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.
4. If the issue persists, contact H3C Support.
Symptom 3
