Removing a power supply
1. Perform the appropriate following action based on whether the PowerConnect B-DCX-4S is
operating:
•
If the PowerConnect B-DCX-4S is not operating during the replacement procedure, go to
step 2.
•
If the PowerConnect B-DCX-4S is operating and will continue to operate during the
replacement, check the power LEDs to verify that the minimum number of power supplies
is functioning. A fully populated PowerConnect B-DCX-4S requires a minimum of one power
supply at all times.
