Power module configuration Follow these guidelines to configure power modules for a device: • Determine the required number of power modules based on the actual power consumption, the power module slot number, and power redundancy design. • Determine the power module redundancy design based on the power source conditions.
Installing and removing the power module CAUTION: Do not install the AC2500 power module and other types of power modules on the same device. The power module slots are either vertically or horizontally oriented, depending on the device model. The power module installation and removal procedure is similar for vertical and horizontal power module slots.
Figure 2 Installation flow NOTE: If the power module slot does not have a blank panel, skip the "Remove the blank panel" procedure. Before installing the power module, prepare an ESD wrist strap and a Phillips screwdriver. Installing the power module Wear an ESD wrist strap, and make sure the wrist strap makes good skin contact and is reliably grounded.

Correctly orient the power module. The blank panel is printed with a diagram of correct installation direction. Follow the direction to orient the power module. Holding the handle of the power module with one hand and supporting the bottom with the other, push the power module into the slot along the guide rails.

Figure 4 Installing the power module (horizontal power module slot) Press the handle back into the notch of the power module. Use the Phillips screwdriver to fasten the captive screw on the handle to secure the power module in the slot. Figure 5 Securing the power module in the slot...
Connecting the power cord WARNING! • Make sure each power cord has a separate circuit breaker. • Turn off the circuit breaker before connecting the power cord. To connect the power cord: Insert the AC power cord plug into the power receptacle on the power module.
Figure 7 Securing the power cord (horizontal power module slot) Connect the other end of the power cord to an AC power receptacle of the power source, and turn on the circuit breaker. Verify that the power input status LED is ON. If the LED is on, the power cord is correctly connected.
Figure 8 Removal flow Before removing the power module, prepare an ESD wrist strap and a Phillips screwdriver. Removing the power cord Turn off the circuit breaker of the power cord. Wear an ESD wrist strap, and make sure the wrist strap makes good skin contact and is reliably grounded.

Use the Phillips screwdriver to loosen the captive screw on the power module. Hold the captive screw and pull out the handle of the power module. As shown in Figure 9, grasp the handle of the power module with one hand and pull it part way out of the slot. Support the bottom of the power module with the other hand, and pull the module slowly out of the slot along the guide rails.
