1.2 Mechanical Assembly
The main mechanical components of the TB8100 BSS are shown in the
following illustrations.
The front panel can be easily removed from the subrack by undoing two
quick-release fasteners. Once the front panel is removed, the control panel
can also be removed from the subrack by undoing a single screw. Refer to
“Replacing Modules” on page 43 for more details.
Note Figure 1.1 above shows the cooling fans and their ducts detached
from the front panel only for the clarity of the illustration. The
cooling fans and ducts are normally screwed to the rear of the front
panel.
Figure 1.1 above also shows the configuration for a typical single 5 or 50W
base station. The PMU occupies the slot at the left end of the subrack, with
the PA directly beside it. The single reciter normally occupies the second
slot from the right of the subrack.
