Power system failure
The switch uses the system status LED (PWR) on the front panel to show how the power system of the
switch is operating. If the system status LED is off, a power supply failure has occurred. Check the
following items:
The power cord is well connected to the switch, and the AC receptacle on the switch and the AC
•
power receptacle are normal.
The external AC power supply system is operating properly.
•
The operating temperature of the switch is normal, and the power module has good ventilation
•
(over-temperature can cause a power module to stop working and enter the protection state).
NOTE:
If the problem persists, contact the HP technical support for help.
