Power supply failure
Symptom
The status LED on a power supply is not steady green (active state) or flashing green (standby
state).
You can use the status LED on a power supply to identify a power supply failure. For more
information about the status LED on a power supply, see HPE PSR250-A & PSR250-A1 Power
Supplies User Guide or HPE PSR450 Power Supply Series User Guide.
Solution
To resolve the issue:
1. Verify that the power cord is correctly connected.
2. Verify that the power source is as required by the power supply.
3. Verify that the operating temperature of the switch is in an acceptable range and good
ventilation is provided for the power supply.
4. If the issue persists, contact the Hewlett Packard Enterprise Support
To replace a power supply, see "Installing and removing a power supply."
Fan tray failure
CAUTION:
If more than one fan tray fails during the switch operation, do not remove the failed fan trays
simultaneously. Replace the fan trays one by one and finish replacing each fan tray within 3 minutes.
Symptom
The status LED on a fan tray is flashing and the system outputs fan tray alarm messages.
Solution
See "Installing and removing a fan tray" to replace the failed fan tray.
Configuration terminal issues
If the configuration environment setup is correct, the configuration terminal displays booting
information when the switch is powered on. If the setup is incorrect, the configuration terminal
displays nothing or garbled text.
