This chapter provides information on the 12E/2FE port adapter and its use on the Cisco 7200 series routers, which includes the Cisco 7206 as a router shelf in a Cisco AS5800 Universal Access Server. This chapter contains the following sections:
The dual-width 12E/2FE port adapter can be installed in any available, horizontally aligned pair of port adapter slots in Cisco 7200 series routers, which includes the Cisco 7206 as a router shelf in a Cisco AS5800 Universal Access Server. Figure 3-1 shows a 12E/2FE port adapter installed in port adapter slot 3 and slot 4 of a Cisco 7206.
Depending on the circumstances, you might need to install a new port adapter or replace a failed port adapter in a Cisco 7200 series router. In either case no tools are necessary; all port adapters available for the Cisco 7200 series connect directly to the router midplane and are locked into position by a port adapter lever.
When removing and replacing a port adapter, you will need an antistatic mat onto which you can place a removed port adapter and an antistatic container into which you can place a failed port adapter for shipment back to the factory.
When a port adapter slot is not in use, blank port adapters must fill empty slots 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 the blank port adapter.
The following sections explain how to remove and install single-width and dual-width port adapters in a Cisco 7200 series router.
Following is the procedure for removing a single-width 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 3-2.)
Step 3 Grasp the handle on the port adapter and pull the port adapter from the router midplane, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter from the chassis slot.
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 3-3.) |
Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag.
This completes the procedure for removing a single-width port adapter from a Cisco 7200 series router.
Following is the procedure for removing a port adapter slot divider from a Cisco 7200 series router:
Step 1 Remove installed single-width port adapters from the slots on both sides of the port adapter slot divider. (See the "Removing a Single-Width Port Adapter" section for instructions.)
Step 2 With one hand, raise the slot divider lever to unlock the slot divider from the chassis. (See Figure 3-4.)
Step 3 With the slot divider lever still raised, use your other hand to pull the slot divider from the chassis. (See Figure 3-5.)
Step 4 Store the slot divider in a location where you can retrieve it for use later.
This completes the procedure for removing a port adapter slot divider from a Cisco 7200 series router.
Following is the procedure for installing a dual-width port adapter in a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 2 If necessary, remove the port adapter slot divider that divides the two port adapter slots you are installing the dual-width port adapter into. (See the "Removing a Single-Width Port Adapter" section for instructions.)
Step 3 Use both hands to grasp the port adapter by its metal carrier edges and position the port adapter so that its components are downward. (See Figure 3-3.)
Step 4 Align the left and right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 3-6.)
Step 5 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into the slot.
| Caution Do not slide the port adapter all the way into the slot until you have connected all required cables. Trying to do so will disrupt normal operation of the router. |
Step 6 With the port adapter halfway in the slot, connect all required cables to the port adapter.
Step 7 After connecting the cables, carefully slide the port adapter all the way into the slot until the port adapter is seated in the router midplane.
Step 8 Move the port adapter lever for each port adapter slot to the locked position. (See Figure 3-7.)
This completes the procedure for installing a dual-width port adapter in a Cisco 7200 series router.
Following is the procedure for removing a dual-width 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 levers for the desired port adapter slots in the unlocked position. The port adapter levers remain in the unlocked position. (See Figure 3-8.)
Step 3 Grasp the two handles on the dual-width port adapter and pull the port adapter from the router midplane, about halfway out of its slot.
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 handles; never touch the port adapter's components or connector pins. (See Figure 3-3.) |
Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag.
This completes the procedure for removing a dual-width port adapter from a Cisco 7200 series router.
Following is the procedure for installing a port adapter slot divider in a Cisco 7200 series router:
Step 1 Position the slot divider so that the slot divider lever faces you and is at the bottom.
Step 2 Align the left and right edge of the slot divider between the guides in the port adapter slot. (See Figure 3-9.)
Step 3 With the left and right edge of the slot divider aligned in the slot guides, slide the slot divider all the way into the slot until you feel the slot divider lock into place (listen for a click).
This completes the procedure for installing a port adapter slot divider in a Cisco 7200 series router.

Step 5 With the port adapter halfway in the slot, connect all required cables to the port adapter.
Step 6 After connecting the cables, carefully slide the port adapter all the way into the slot until the port adapter is seated in the router midplane.
Step 7 Move the port adapter lever to the locked position. (See Figure 3-11.)
This completes the procedure for installing a port adapter in a Cisco 7200 series router. Proceed to "Installing the 12E/2FE Interface Cables" to connect the necessary cables to your port adapter.
