Cisco 7200 Series and the 4R Port Adapter
Caution Do not slide the port adapter all the way into the slot until you have connected all required

Step 6 After connecting all required port adapter cables, carefully slide the port adapter all the way into the
slot until you feel the port adapter’s connectors seat in the midplane.
Step 7 Move the port adapter lever to the locked position. shows the port adapter lever in the locked position.
Note If the port adapter lever does not move 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
move the port adapter lever to the locked position.

Attaching 4R Port Adapter Interface Cables
The Token Ring ports on the 4R port adapter run at either 4 or 16 Mbps. You need one Token Ring
interface cable for each 4R port adapter interface you want to use. Token Ring interface cables are not
available from Cisco Systems, but are commercially available through outside cable vendors. Port
adapters have a handle but this handle is not shown in to allow a full view of detail on the 4R port
adapter’s faceplate.
Use the following procedure to attach Token Ring cables to the 4R port adapter:
