Cable Rings and Troughs
Vertical cable rings at the rear of the bay allow for routing of cross-connect jumpers up and
down each side of the bay. Cable troughs at the top and bottom of the bay provide for the
routing of cross-connect jumpers between bays.

Cross-Connect System
The cross-connect system bay is an unequal flange type, 213 × 65.88 × 30.48 cm (84 × 25.94 × 12
inches). Shelf mounting holes are spaced at 2.54 cm (1 inch). An AC outlet may be provided at
the bottom front of the bay as an auxiliary source of 110 Vac primary power.
