Cisco 7200 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
the Cisco 7200 series routers. This chapter contains the following sections:
• Installation Overview, page 4-1
• Removing a Port Adapter, page 4-2
• Installing a Port Adapter, page 4-4
Note The Cisco 7206VXR and the Cisco 7206 can be used as router shelves in a Cisco AS5800
Universal Access Server. For information about the Cisco 7206VXR and the Cisco 7206 as router
shelves, see the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.
Installation Overview
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 the
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 Cisco 7200 series 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-TXand PA-FE-FXcan be installed inany available port adapterslot inCisco 7200 series
routers. Figure 4-1 shows a Cisco 7206 with a PA-FE-TX installed in slot 4.
