Step 3
If necessary, remove the blank power supply filler plate from the chassis power supply bay opening by
loosening the captive installation screws.
Step 4
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.
Note
Step 5
Grasp the power supply handle with one hand. Place your other hand underneath the power supply. Slide the
power supply into the power supply slot, but do not seat the power supply completely. Provide ample room
