Replacing the Power Supply
If the E3800 switch is configured with redundant power supplies, the switch
will not suffer any loss of traffic or performance if a power supply fails.
Replace the failed component as soon as possible. The PS (Power Supply)
LED will blink simultaneously with the switch Fault LED indicating a power
supply has failed.
To remove an AC power supply:
1. Remove the AC power cable from the failed power supply’s connector.
2. Grasping the handle of the failed power supply, release the locking
mechanism by squeezing the latch handle while removing the failed
power supply.

3. Insert the new power supply. Slide it in all the way in until the locking
mechanism locks.
