In the patch-cord management study, there were 1066 brackets
or channels (figure 1) implemented in the vertical management system.
This equals 8.5 vertical managers per rack, cabinet, etc., of the 124
total inspected at the 20 sites. This was considered adequate vertical
management by inspection team.
Vertical management systems were clearly more prone to
problems than horizontal ones. The study showed many vertical management
systems were incapable of accommodating the amount of cable slack accumulated
in the patching system.
Even with larger, more robust vertical managers, the problem
of slack accumulation persists due to longer cords than required after
routing through the management system. (Achilles heel - Figure 2, 3 &
