Cisco IOS Bridging and IBM Networking Configuration Guide
The Cisco 7200 series router supports online insertion and removal (OIR), which allows you to install
or remove port adapters while the system is operating.
Note In this chapter, references to Channel Port Adapter (CPA) correspond to both the ECPA and
the PCPA. Refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines
publication for more details.
ESCON Channel Port Adapter
An ECPA is classified as a high-speed port adapter providing a single ESCON physical channel
interface. Current Cisco 7200 configuration guidelines recommend using no more than three high-speed
port adapters in a single Cisco 7200 router.
Parallel Channel Port Adapter
A PCPA provides a single parallel channel physical interface supporting 3.0 or 4.5 Mbps data transfer
rates.
Differences between the CIP and CPA
Table 4 illustrates the differences between the CMCC adapters.
