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 port adapter from a Cisco uBR7200 series router.
Installing a Port Adapter
Following is the procedure for installing a 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 carrieraligned in the slotguides, gently slide the portadapter halfway into
the slot.
Caution Do not slide the port adapter all the way into the slot untilyou 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 Secure the port adapter:
• 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 pullthe port adapter halfway out of the slot,
reinsert it, and slide the retention clip up to the locked position.
