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:
