Maintenance and troubleshooting
Power supply failure
Symptom
The power supply status LEDs are not steady green.
For the HPE 5130 24G 4SFP+ 1-slot HI and HPE 5130 48G 4SFP+ 1-slot HI switches, examine the
PWR1 or PWR2 LED of the switch to identify power supply failure.
For the HPE 5130 24G PoE+ 4SFP+ 1-slot HI and HPE 5130 48G PoE+ 4SFP+ 1-slot HI switches,
examine the PWR1 or PWR2 LED of the switch and the LEDs on the power supply to identify power
supply failure.
• For more information about the PWR1 and PWR2 LEDs on the front panel of the switch,
see Table 20.
• For more info
rmation about the LEDs on a power supply, see HPE PSR720-56A Power Supply
User Guide and HPE PSR1110-56A Power Supply User Guide.
Solution
To resolve the problem:
1. Verify that the switch power cord is correctly connected.
2. Verify that the power source meets the requirement.
3. Verify that the operating temperature of the switch is in an acceptable range and the power
supply has good ventilation.
4. If the problem persists, contact HPE Support.
5. To replace a hot swappable power supply, see "Installing/removing a power supply."
Fan tray failure
CAUTION:
• Do not power on the switch when the switch does not have a fan tray or has only one fan tray
installed.
• If both fan trays fail, replace them within 2 minutes.
• If one fan tray fails, perform either of the following tasks:
{ If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and
make sure the failed fan tray remains in position before the replacement.
{ If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
The switch supports hot swapping of fan trays. When a fan tray fails, see "Removing a fan tray" and
"Installing a fan tray" to re
place the fan tray. If the problem persists, contact HPE Support.
