Figure 4-15 shows the recommended fibre-optic cable routing for a single-
carrier cabinet system with a cable slack manager or on a raised floor.
In these situations, use the following steps to route the cable:
1. Route the fibre-optic cable up toward the top of the cabinet. The excess
cable should be looped and draped from the B25A cable clamp on the
top ground plate in the stack.
2. Dress the cable running up the back of the cabinets by tie wrapping the
cable to the outside of the B25A cable clamp (do not put the cable inside
the clamp holding the B25A cables).
