Note: Before cabling the lower CMA, note the following routing of the cables.
For best results, the cables that are supported by the upper CMA are inserted
into IOM B (right hand side looking at the rear) and the lower CMA cables
are routed to IOM A (left hand side looking at the rear) in a "criss-cross"
pattern. See the Special Considerations for Cable Routing (page 154) for
more information.
