Port Adapter Overview
The PA-FE-TX and PA-FE-FXport adapters provide a 100-Mbps, 100BaseT Fast Ethernet interface
and support both full-duplex and half-duplex operation. Refer to the “Fast Ethernet Overview”
section on page 1-9 for additional information. Figure 1-1 shows the PA-FE-TX and Figure 1-2
shows the PA-FE-FX.
Note While the VIP2 supports online insertion and removal (OIR), individual port adapters do not.
Toreplace port adapters, you must first remove the VIP2 from the chassis, then replace port adapters
as required.
Cisco 7100 series routers, Cisco 7200series routers, and Cisco uBR7200 series universal broadband
