TB9100/P25 CG/P25 TAG Installation and Operation Manual Replacing Modules 107

Notice You must connect the fans to the correct sockets on the fan
contact board. If the fan connections are reversed, the wrong fan will be
activated when a module needs cooling. The module may then fold back
and shut down. When you power up the base station, check that the
PMU fan runs first, followed by the PA fan. Each fan will run for about
five seconds.
Notice You must refit the correct duct to the PA fan. There are several
small but important differences between the duct for a 5W or 50W PA
and the duct for a 100W PA. Refer to Figure 7.4 on page 115 for more
details.
