1. Remove the left rear cover of the power supply frame, as viewed from 

the rear, to expose the wiring connections at the rear of the Multi-
Output power unit. See 

If this is the upper power supply in a redundant power system, also 
remove the left rear cover of the lower power supply.

2. Disconnect the two connectors that plug into the jacks at the top of the 

left rear compartment. (Hint: To release the connectors, squeeze the 
near and far side tabs on the large connector, and the left and right side 
tabs on the four-wire connector.

If this is the upper power supply in a redundant power system, also 
disconnect the corresponding two plugs in the lower power supply 
frame.

3. Unplug the small multiwire connector that connects to the top of the 

circuit board containing the power supply indicator LEDs.

4. At the upper right of the compartment, on the rear of the power supply 

unit, remove the terminal block cover (if present) and disconnect the 
blue and brown wires from the terminal block. The green/yellow wire 
may be left in place.

5. Push the two wires back through the hole into the frame cavity, so they 

will not interfere when the sled is removed.
