8 Second-Generation Channel Interface Processor (CIP2) Installation and Configuration
CIP2 Installation Prerequisites
Verifying ECA Models by Examining ECA Hardware
Verify which type of ECA you have on your CIP2; it should be one of the following:
• The latest ECA model (see Figure 1 on page 8)
• The earlier ECA model (see Figure 2 on page 8)
Note Because ECAs ship under identical product numbers, you must refer to the different part
numbers (73-xxxx-xx) and component layouts of the two ESCON channel adapter cards, which are
shown in Figure 1 and Figure 2, then make the appropriate comparisons to the CIP2/ECA assembly
shipped to you.
The latest ECA model is Part Number 73-2185-02 or later (see Figure 1); the earlier ECA model is
Part Number 73-1201-02 or earlier (see Figure 2).
If you determine that you have the latest ECA (see Figure 1), you must observe and comply with the
preceding ESCON channel adapter software and microcode prerequisites.
If you determine that you have the earlier ECA (see Figure 2), no further action is required.
