Step 2 Remove the two Phillips-head retaining screws from the XENPAK module slot cover, and store them for
later use.
Step 3 Remove the cover, as shown in Figure 2-51.

Step 5 Align the XENPAK module with the guide rails inside the module slot, and slide the module into the
opening until the back of the XENPAK faceplate is flush with the switch faceplate. (See Figure 2-52.)
