Power supply failure

Symptom

The power supply status LEDs are not steady green.
For the HPE 5510 24G SFP 4SFP+ HI, HPE 5510 24G 4SFP+ HI, and HPE 5510 48G 4SFP+ HI,
examine the PWR1 or PWR2 LED of the switch to identify power supply failure.
For the HPE 5510 24G PoE+ 4SFP+ HI and HPE 5510 48G PoE+ 4SFP+ HI, 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

For more information about the LEDs on a power supply, see HPE PSR720-56A Power Supply
User Manual, and HPE PSR1110-56A Power Supply User Manual.

Solution

To resolve the problem:
a. Verify that the switch power cord is correctly connected.
b. Verify that the power source meets the requirement.
c. Verify that the operating temperature of the switch is in the acceptable range and the power
supply has good ventilation.
d. If the problem persists, contact HPE Support.

Fan tray failure

WARNING!
• 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 during operation, 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
"Installing a fan
