Cisco 7200 Series and the PA-MC-2T3+

This chapter provides information on the PA-MC-2T3+ port adapter and its use in the Cisco 7200 series routers. This chapter contains the following sections:

Installation Overview

The PA-MC-2T3+ port adapter is used in the Cisco 7200 series routers and can be installed in any of the available port adapter slots. Figure 4-1 shows a PA-MC-2T3+ port adapter installed in port adapter slot 1 of a Cisco 7206.

Figure 4-1: Cisco 7200 with a PA-MC-2T3+ Port Adapter---Cisco 7206 shown

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case no tools are necessary; all port adapters available for Cisco 7200 series routers connect directly to the router midplane and are locked into position by a port adapter lever. When removing and replacing a port adapter, you 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.

Note The Cisco 7200 series routers support OIR; therefore, you do not have to power down the routers when removing and replacing a PA-MC-2T3+ 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 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.)

Figure 4-2: 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, there is no midplane connection, so pull the blank port adapter all the way out of the chassis slot and proceed to the "Installing a Port Adapter" section.)

Note

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 port adapter components or connector pins. (See Figure 4-3.)

Figure 4-3: Handling a Port Adapter

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 is to be returned to the factory, immediately place it in a static shielding bag.

This completes the procedure for removing a port adapter from a Cisco 7200 series router.

Installing a Port Adapter

Following is the procedure for installing a new 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 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 4-3).

Step 3 Align the left and right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 4-4.)

Step 4 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 disrupts normal operation of the router.

Step 5 With the port adapter halfway in the slot, connect all required cables to the port adapter.

Step 6 After connecting all required cables, carefully slide the port adapter all the way into the slot until the port adapter is seated in the router midplane.

Step 7 After seating the port adapter in the router midplane, move the port adapter lever to the locked position. Figure 4-5 shows the port adapter lever in the locked position.

This completes the procedure for installing a new port adapter in a Cisco 7200 series router. Proceed to the "Installing the PA-MC-2T3+ Interface Cables" chapter to connect the necessary cables to your port adapter.
