Mounting — Multiple mount
The multiple-mount MADU may be rack or cabinet mounted. The MADU may be
mounted in 19, 23, or 25 inch racks. If the MADU is to be mounted in a cabinet,
the cabinet must be 23 or 25 inches wide to provide clearance for the cabling.
Power
Each MADU circuit pack is powered from an individual transformer which is
plugged into an AC power source. The transformer may be plugged directly into a
wall outlet for four or fewer units. For more than four MADU packs, transformers
should be plugged into a multiple-mount carrier’s power distribution box or
commercially available power strip with an RF filter.
