Cisco 7200 Series and the 4R Port Adapter
Removing a Port Adapter
Use the following standard procedure 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. (Refer to Figure 16.)
Figure 16 Placing the Port Adapter Lever in the Unlocked Position (Cisco 7206 Shown)
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 from the port adapter 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 port adapter slot.
Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter’s
components or connector pins. (Refer to Figure 17.)
