Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Power Supply
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection installation
instructions, see the
“System Ground Connection” section on page 3-19.
Step 2 Verify that power is off to the DC circuit that is connected to the power supply you are installing.
Caution Use both hands to install and remove power supplies. Each DC-input power supply weighs between 22
pounds (9.9 kg) and 33 pounds (15 kg).
Step 3 Grasp the power supply handle with one hand, and place your other hand underneath the power supply.
Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the
bay (
Figure 5-72).
