Power supply failure
Fixed power supply failure
The H P 513 0 -24G-4SFP+ EI, HP 513 0 -24G-2SFP+-2XGT EI, and H P 513 0 -24G-4SFP+ EI BR switches use
fixed power supplies and support only AC power input. The H P 513 0 -24G-PoE+-4SFP+ (370W) EI, HP
513 0 -48G-4SFP+ EI, H P 513 0 -24G-PoE+-4SFP+ (370W) EI BR, H P 513 0 -48G-PoE+-4SFP+ (370W) EI BR,
H P 513 0 -48G-2SFP+-2XGT EI, H P 513 0 -24G-PoE+-2SFP+-2XGT (370W) EI, HP
513 0 -48G-PoE+-2SFP+-2XGT (370W) EI and H P 513 0 -48G-PoE+-4SFP+ (370W) EI switches use fixed
power supplies and support AC power input, RPS power input, and concurrent AC and RPS DC inputs.
To identify a fixed power supply failure, examine the system status LED and the RPS status LED of the
switch.
Table 8 Fixed power supply 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
supply has good ventilation. Over-temperature can cause the power supply to stop working and
enter the protection state.
4. If the problem persists, contact HP 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.
