Installing the Cross-Connect Field
The preferred cross-connect field location is directly behind the switch cabinet. The first
column of 66-type connecting blocks should be aligned with the left side of the switch cabinet
(see Figure 4-15). This arrangement allows for growth on the right side of the cross-connect
field.
