INSTALLATION CONSIDERATIONS

DNI-1B mounts flush into both unequal flange and equal flange (EIA or

WECO) racks/bays—the 112-circuit version in 19" (48.3 cm) bays, the

128—circuit version in 23" (58.4 cm) bays. Rack configuration is limited

mainly by the number of cables a bay can accommodate. Telect recom-

mends a maximum of 22 DNI-1B panels per bay:

• Allows easy access for maintenance.

• Keeps the panels within reach.

• Provides enough room for cable routing.

Here are the DNI-3 space requirements:
