Fixed Power Module Failure

The S5800-56C, S5800-56C-PWR, S5800-32C-PWR and S5800-32C use fixed power modules. Each
of these fixed power modules has three input modes, namely, AC input, RPS input and both.
You can check whether the power system of the switch fails by viewing the system status LED and RPS
status LED on the front panel of the switch. For details, refer to

AC input
When the switch adopts AC input, you can check the power supply status by viewing the system status
LED. If the system status LED is off, an AC input failure occurs. Then do the following:
Check whether the AC power cord is well connected to the switch, whether the AC receptacle on
the switch and the AC power socket are faulty.
Check whether the external AC power supply system is normal.
Check whether the operating temperature of the switch is normal, and whether good ventilation is
provided to the power supply (the power module may stop working and enter the protection state
due to over-temperature).
RPS input
When the switch adopts RPS input, you can check the power supply status by viewing the system
status LED or RPS status LED. If the system status LED or RPS status LED is off, an RPS input failure
occurs. Then do the following:
Check whether the switch is well connected to the external RPS power supply.
Check whether the external RPS power supply works normally.
Check whether the operating temperature of the switch is normal, and whether good ventilation is
provided to the power supply (the power module may stop working and enter the protection state
due to over-temperature).
RPS&AC input
When the switch adopts both RPS and AC inputs, you can check the power supply status and the input
status of each line by viewing the system status LED and RPS status LED.
1) The system status LED is off.
Both the AC input and RPS input are faulty. Then do the following:

Description
The switch is powered off.
The AC input is normal, and the RPS is in the
position or works normally.
RPS input is normal, but AC input fails or AC input is
not connected.
RPS is not connected.
