Second-Generation Channel Interface Processor (CIP2) Installation and Configuration 23
What Is the CIP2
CIP2 Model Numbers
There are three CIP2 carrier types, which offer the following five interface adapter combinations:
• One PCA on a PCA/ECA carrier—CX-CIP2-PCA1(=)
• Combination PCA and ECA—CX-CIP2-ECAP1(=)
• One ECA on a dual carrier—CX-CIP2-ECA1(=)
• Two ECAs on a dual carrier—CX-CIP2-ECA2(=)
• Two PCAs on a dual carrier—CX-CIP2-PCA2(=)
Add an equal sign (=) to the product number when you order interface processors as spares.
The ECA has a female, duplex connector, and the PCA has a female, DB-78 connector. Figure 11
shows the ECA and PCA interface combinations that are available.

Caution
The latest ECA model has specific software, hardware, and microcode requirements that
must be observed to ensure proper system operation. To determine if you have the earlier ECA, or
the latest ECA, on your CIP2, refer to the section “ESCON Channel Adapter Software, Hardware,
and Microcode Prerequisites” on page 7.
