Switch Installation

Installing and Removing XENPAK Modules (Catalyst 3750G-16TD Switch)

Removing a XENPAK Module

To remove a XENPAK module, follow these steps:

Step 1

Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2

Disconnect the cable from the XENPAK module. For fiber-optic modules, install the optical bore dust

plugs.

Step 3

Loosen the two captive installation screws that secure the XENPAK module in the slot.

Step 4

Carefully pull on the two captive installation screws to disconnect the XENPAK module from the slot.

Step 5

Grasp the edges of the XENPAK module, and carefully slide it out of the slot, as shown in

Figure 2-53

Removing a XENPAK Module

Step 6

Use two Phillips-head screws to attach the XENPAK module slot cover to the switch front panel, as

shown in

Figure 2-54

Warning

Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous

voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might

disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate

the system unless all cards and faceplates are in place.
