8.9 Final Reassembly
Important You must fit the correct type of front panel to your base sta-
tion. The different types of front panel and fan ducts are
explained in “Replacing the Front Panel Fans” on
page 102.
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
“Appendix B – Inter-Module Connections” on page 111). Other-
wise the panel may not fit properly, or you may damage the cables.
2. Refit the Front Panel
a. Ensure that the fasteners
b are in the unlocked position.
b. Fit the front panel onto the locating pegs on the subrack.
c. Secure each fastener with a quarter turn clockwise.
d. Push the self-aligning D-range connector
c fully in.
3. Before powering up the base station, check that all power, RF and
system cables are connected correctly and securely at the rear of the
base station.
Important When refitting modules, make sure they are fitted correctly
into the subrack and all retaining clamps are securely tight-
ened. The recommended torque for the retaining clamp
screws is 17 lbf ·in (1.9 N·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 connec-
tion between the modules and the subrack.
