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.
Concurrent RPS and AC inputs
If the system status LED is off, the AC power supply and the RPS both have an input failure.
To resolve the problem:
a. 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.
b. Verify that the AC power source is operating correctly.
c. Verify that the switch is securely connected to the RPS.
d. Verify that the RPS is operating correctly.
e. 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.
f. If the problem persists, contact HP Support.
If the system status LED is on but the RPS status LED is steady yellow, an AC input failure has
occurred.
To resolve the problem:
a. 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.
b. Verify that the AC power source is operating correctly.
c. If the problem persists, contact HP Support.
If the system status LED is on but the RPS status LED is off, an RPS input failure has occurred.
To resolve the problem:
a. Verify that the switch is securely connected to the RPS.
b. Verify that the RPS is operating correctly.
c. If the problem persists, contact HP Support.
Hot-swappable power supply failure
The H P 513 0 -24G-SFP-4SFP+ EI switch uses hot-swappable power supplies. You can determine the power
supply operating status by examining the power supply LEDs PWR1 and PWR2 on the switch front panel.
For descriptions about the PWR1 and PWR2 LEDs, see "Appendix C Ports and LEDs."
If the LED indicates a power supply failure, perform the following steps:
1. Verify that the power supply model is as required.
2. Verify that the power supply is installed correctly in the switch.
3. Verify that the switch is operating in the acceptable temperature range.
4. If the problem persists, contact HP Support.
