IBM BC-203 Differences between the CIP and CPA, ESCON Channel Port Adapter, Product Differences

Overview of IBM Networking

CMCC Adapter Hardware

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.
