Step 2 Use a torque wrench with a torque of 0.6 N•m to connect the SMA straight male connector on
a jumper to the ANT port on the pRRU3901 panel.
Tighten it with hands, and then use a torque wrench to tighten it with a rotational speed of less
than or equal to 2.4 rpm to tighten it.
Step 3 Connect the type N female connector of the jumper to the type N male connector of the RF
feeder connected to the built-in antenna.
Tighten the feeder close to the type N connector to ensure that the jumper is not tightened. In
this way, the connectors on both ends of a jumper are not affected by the external force.
