Mechanical Assembly
This section illustrates the main mechanical components of the base
station.
below shows the configuration for a typical dual 50W base
station. The subrack has six slots, numbered from right to left as viewed
from the front of the subrack. The PMU occupies slots 5 and 6, with the
reciter and PA pairs to the right of it in slots 1 to 4. Each PA is mounted
vertically with its heatsink facing its associated reciter. The PMU and each
reciter/PA pair have their own cooling fans.
The front panel can be easily removed from the subrack by undoing two
quick-release fasteners. Refer to
“Replacing Modules” on page 123
for
more details.
