6.1 Fan Assembly

The fan assembly dissipates heat from the BTS3900C cabinet.

A BTS3900C cabinet has two fan assemblies. The one at the left bottom in the OMB is the outer
air circulation fan assembly and the one at the left top in the OMB is the inner air circulation
fan assembly.

Exterior

The inner air circulation fan assembly has the same exterior as the outer air circulation fan
assembly, as shown in
