Port Adapter Overview
The PA-4R-DTR, shown in
Figure 1-4
provides up to four IBM Token Ring or IEEE 802.5 Token Ring
interfaces. You can set each Token Ring interface for 4-Mbps or 16-Mbps, half-duplex or full-duplex
operation, and each interface can operate as a concentrator port or a classic Token Ring station. All
Token Ring ports run at wire speed.
Note
Port adapters have a handle, but this handle is not always shown in figures in this publication to allow a
full view of the detail on the port adapter faceplate.

Note
While the VIP2 supports online insertion and removal (OIR), individual port adapters do not. To replace
port adapters in Cisco 7000 series and Cisco 7500 series routers, you must first remove the VIP2 from
the chassis and then replace port adapters as required. Cisco 7200 series routers support OIR of port
adapters.
