1. Before fitting the front panel, ensure that all cables are secured and
positioned correctly so they are clear of the fan ducts (refer to

the panel may not fit properly, or you may damage the cables.
2. In 50W base stations, check that the airflow separator is fitted
correctly.

4. Before powering up the base station, check that all power, RF and

Notice When refitting modules, make sure they are fitted correctly
into the subrack and all retaining clamps are securely tightened. The
recommended torque for the retaining clamp screws is 17lbf·in
(1.9N·m). As well as holding the modules in place, the retaining clamps
push the modules hard against the rear rail of the subrack to ensure a
good ground connection between the modules and the subrack.
