Cisco uBR7200 Series and the
PA-FE Port Adapters
This chapter provides information on the PA-FE-TX and PA-FE-FX port adapters and their use in
Cisco uBR7200 series universal broadband routers. This chapter contains the following sections:
• Installation Overview, page 5-1
• Removing a Port Adapter, page 5-2
• Installing a Port Adapter, page 5-4
Installation Overview
You might need to install a new port adapter in a Cisco uBR7200 series universal broadband router
or replace a failed port adapter in the field. In either case, no tools are necessary; all port adapters
available for the Cisco uBR7200 series connect directly to the router midplane and are locked into
position by a port adapter lever (Cisco uBR7223) or retention clip (Cisco UBR7246). 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 Cisco uBR7200 series universal broadband routers support online insertion and
removal (OIR); therefore, you do not have to power down the routers when removing and replacing
a PA-FE.
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.
The PA-FE-TX and PA-FE-FX can be installed in any of the available port adapter slots in a
Cisco uBR7200 series universal broadband router. Figure 5-1 shows a PA-FE-TX installed in port
adapter slot 2 of a Cisco uBR7200 series router.
