TB9400 Installation and Operation Manual

© Tait Limited March 2015

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 

 for 

more details.
