90 Part E: Configuring the Base Station © Tait Electronics Limited December 2007
Select fan type
The Select fan type area (Configure > Base station > Fan Control) lets you tell
the base station what kind of fans (both PA and PMU) it is fitted with.
Note: Fans used in the TB8100 must have the correct wiring. Power
and ground (2-wire fans) or power, ground and rotation detect (3-
wire fans). Both fans in a subrack should be of the same type.
Q Specify whether the fan type is 2-wire or 3-wire. If you select 3-wire, the
base station will use the third wire as a rotation detector. If it has turned the
fan on but does not detect rotation, it activates the ‘Fan failed’ alarm.
