Power module failure
Fixed power module failure
The S5130-28S-EI, S5130-28S-PWR-EI, and S5130-28TP-EI switches use fixed power modules and support
only AC power input. The S5130-28S-HPWR-EI, S5130-28TP-PWR-EI, S5130-52S-EI, S5130-52S-PWR-EI,
S5130-52TP-EI, and S5130-52TP-PWR-EI switches use fixed power modules and support AC power input,
RPS power input, and concurrent AC and RPS DC inputs.
To identify a fixed power module failure, examine the system status LED and the RPS status LED of the
switch.

LED Mark Status Description
System
status

SYS Off The switch is powered off.
RPS
status
LED
RPS
Steady green
The AC input is normal, and the RPS is in position or working
normally.
Steady yellow
RPS power input is normal, but AC input has failed or AC input is
not connected.
Off No RPS is connected.
AC input
If the system status LED is off, an AC input failure has occurred.
To resolve the problem:
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 operating temperature of the switch is in the acceptable range, and the power
module has good ventilation. Over-temperature can cause the power module to stop working and
enter the protection state.
4. If the problem persists, contact H3C Support.
RPS DC input
If the system status LED or RPS status LED is off, an RPS input failure has occurred.
To resolve the problem:
1. Verify that the switch is securely connected to the RPS.
2. Verify that the RPS is operating correctly.
