Installing the 7781CM in the Field

Deploying the 7781CM

Installing the Cable Power Tap

The CATV coaxial cable used in the field deployment must have 45 to 90 VAC power
multiplexed with the RF signal on the coaxial cable, since the 7781CM Connector B is used
for both electrical power and the RF signal.

Ruckus Wireless recommends installing a cable power tap (Antronix MGT2000-SDPE tap,
or equivalent) close to the 7781CM. Refer to the manufacturer’s instructions to mount the
cable power tap on the coaxial cable.
