Depending on your circumstances, you might need to install a new port adapter in a Cisco 7100 series router or replace a failed port adapter in the field. All port adapters available for the Cisco 7100 series connect directly to the router and are locked into position by a locking tab with two screws (see Figure 7-1 or Figure 7-2). You need a number 2 Phillips screwdriver to loosen the screws.

Note The Cisco 7100 series routers support online insertion and removal (OIR); therefore, you do not have to power down the router when removing and replacing a port adapter.

When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter.

Removing a Port Adapter

Following is the procedure for removing a port adapter from a Cisco 7100 series router:

Step 1 Attach an ESD-preventive wrist strap between you and the chassis. See Figure 7-1 or Figure 7-2 for the location of the ESD plug.

Step 2 Use a number 2 Phillips screwdriver to loosen the screws on the locking tab; then slide the tab down to the unlocked position. (See Figure 7-1 or Figure 7-2.)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the router, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter completely out of the chassis slot.

Note As you disengage the port adapter from the router, OIR administratively shuts down all active interfaces on the port adapter.

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.

Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter’s components or connector pins. (See Figure 7-3.)
