Before you begin

Before installing the power supply, see the Installation Guidelines, on page 72.

Procedure

Step 1 Turn off DC power. To ensure that power is off, change the circuit breakers to the OFF position, and tape the

circuit-breaker switches in the OFF position.

Step 2 Remove the plastic safety cover from the power supply terminal blocks.

If you are not replacing a DC power supply, go to Step 5.

Note

Step 3 Use a number-2 Phillips screwdriver to remove the DC-input power wires from the power terminals.

Step 4 Press the release latch at the right side of the power supply module inward, and pull the power supply out.

Step 5 Insert the power supply in the power-supply slot, and gently push it into the slot. When correctly installed,

the DC power supply (excluding the extraction handle) is flush with the switch rear panel.
