Connecting radio module sector ports
The radio module has three SMA connectors per sector on the front and rear of the module.
Below the radio module there are matching SMA connectors in the chassis that are pre-wired

the front and rear of the chassis.
Procedure
1. Connect one end of a jumper cable to an SMA port on the radio module.
2. Connect the other end of the jumper cable to the SMA port on the chassis directly below
the first connection.
3. Repeat step 1 and step 2 for the remaining eight SMA connectors.
4. Use the torque wrench to tighten each SMA connector to 1 N-m (9 in-lbs).
