Installing a DC Power Supply Module
Perform the following procedure to install a power supply module:
Procedure
Step 1
Ensure that the system (earth) ground connection has been made. For ground connection installation instructions,
see the
Installing the Chassis Ground Connection
section.
Step 2
If present, remove the blank power supply filler plate from the chassis power supply bay opening by loosening
the captive installation screws.
Step 3
Verify that power to the DC circuit connected to the power supply you are installing is off. To ensure that
power has been removed from the DC circuits, locate the circuit breakers for the DC circuits, switch the circuit
breakers to the OFF position, and tape the circuit-breaker switches in the OFF position.
Step 4
Grasp the power supply metal tab with one hand. Place your other hand underneath the power supply. Slide
the power supply into the power supply bay as shown in the figure below. Make sure that the power supply
is fully seated in the bay.

Step 5
Tighten the captive installation screw of the power supply. The recommended maximum torque is 5.5 in.-lb
(.62 N-m).
If you are installing a redundant DC power supply, repeat these steps for the second power source too.
