Power supply installation
Use this procedure to remove and replace a power supply.
The PowerConnect B-DCX can continue operating during the replacement if:
At least one 220 VAC power supply is operating,
At least two 110 VAC power supplies are working.
The PowerConnect B-DCX-4S can continue operating during the replacement if the second 220 VAC power supply is
operating,
Time and items required
The replacement procedure for each power supply takes less than 5 minutes. A power supply unit or filler panel is
required for the power supply replacement.

Removing a power supply
1. Perform one of the two following tasks:
For the PowerConnect B-DCX:
• If the PowerConnect B-DCX is not operating during the replacement procedure, go to step 2.
• If the PowerConnect B-DCX 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 requires a minimum of one power supply at all times.
For the PowerConnect B-DCX-4S:
• 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.
2. Turn off the power switch.
3. Remove the power cord.
