Patch Panel Cabling for Redundancy
You can connect the patch panels with the interface modules for redundancy, using the Y-cables. The Y-cable
stub lengths are reduced, so that the cable does not exceed from the rack spacer. The Y-cables are numbered
based on the different stub length. Cable lengths differ for even numbered and odd numbered slots in the
chassis.
