Step 15 Slide the front bezel cover onto the four corner posts of the chassis and then push down, so that the posts are seated in the grooves above the cover holes. Route the AC power cables through the notch on the right side of the cover.

Removing and Replacing the PRE Module

It is not necessary to configure the PRE module if you are installing or replacing a second PRE. The system automatically downloads the necessary configuration information from the primary PRE.

Removing the PRE Module

		Use the following procedure to install a new PRE module, or to replace an existing PRE module.
	Step 1	Be sure you are properly grounded.
	Step 2	If necessary, remove the blank cover from the PRE module slot and discard.
	Step 3	Disconnect any interface cables from the PRE module if necessary.
	Step 4	Remove the PC media card from the PRE module (see the “Removing and Installing a PC Media Card”
		section on page 5-34).
	Step 5	Unscrew the top and bottom captive screws on the PRE module (see Figure 5-25).
