Port Adapter Overview

The PA-FE-TX and PA-FE-FX port 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. To replace port adapters, you must first remove the VIP2 from the chassis, then replace port adapters as required.

Cisco 7100 series routers, Cisco 7200 series routers, and Cisco uBR7200 series universal broadband routers support online insertion and removal (OIR) of port adapters.
