Removing a Port Adapter
PA-4T+ Synchronous Serial Port Adapter Installation and Configuration4-2
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 air flow 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
Take the following steps to remove a port adapter from a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 2 Place the port adapter lever for the desired port adapter slot in the unlocked position. The
port adapter lever remains in the unlocked position. (See Figure 4-2.)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the midplane, 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 midplane, 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 4-3.)
