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.
