Routing Cables From Cabinet to Cross-Connect Field
The following guidelines should be followed when routing cables from
the cabinet to the cross-connect field.
●

●
When cable routing is to the top/bottom of the cross-connect
field, each port cable is connected at the cabinet and then routed
along the front trough of the cable slack manager to the
connecting/terminal block where the cable is to be terminated.
Enough slack must be left at the cabinet end of the cable to allow
for proper dressing of the cables (Figure 3-50).
Route the cable from the cabinet to the wall. Place the cable
beside one of the rows of columns in the cable slack manager
(see Note).
Note: Retainers mounted on the columns keep the cable
from protruding above the top of the base of the cable slack
manager.

Determine the length of the cable required to reach from the cable
slack manager to the assigned connecting/terminal block.
The cable must be supported on the wall using D rings.
Cable slack is stored by coiling the cable around the columns in
the cable slack manager. The first run should always go across
the full length of the five columns in the cable slack manager.
Connect the cable to the assigned connecting/terminal block.
