Installing a Port Adapter

Installing a Port Adapter

Following is the procedure for installing a new port adapter in a Cisco uBR7200 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 6-4.)

Step 3 Align the left and the right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 6-5.)

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 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 Place the port adapter retention clips or levers in the locked position:

•For a Cisco uBR7246, slide the port adapter retention clip up to the locked position. (See Figure 6-6).

Note If the retention clip does not slide up to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and slide the retention clip up to the locked position.
