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, S5130-28PS-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.
NOTE:
For 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, the "Power
x
failed" message is displayed
when there is only one power input because the switch cannot identify whether the other power line
is not connected or has an input failure.
To identify a fixed power module failure, examine the system status LED and the RPS status LED of
the switch.
Table 7 Fixed power module LED description
LED Mark Status
Description
System
status
LED
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.
