Addressing
The second CAP's operation is similar to a single CAP operation, but the
numbering scheme changes and addressing is different.
Hardware:
Using the SL8500 firmware notation of Library, Rail, Column, Side, and Row,
the dual CAPs, in a single base library, with no expansion modules, now
appear as:

Software:
For addressing purposes, software needs a fixed location for the CAP, and
uses: ACS,LSM,CAP#.
The LSM address is associated with the second rail in each library because
there is no adjacent CAP magazine for the top rail in an SL8500 library.
See
Figure 11 on page 19
In this example, a three library complex is used for CAP addressing.

This addressing example uses a single base library configuration with no storage
expansion modules. When adding expansion modules, the column number increases
by 8 for each module added (23, 31, 39, 47, and 55).
Previously with single CAP operations, CAP A was addressed as 1.
With dual CAP operation, CAP B is 1 and CAP A is 2
This uses the inside (2) outside (1) numbering scheme for side.
The row is always 0, which is the magazine handle.
