Paradyne 3000 manual Fan Module Installation

COMSPHERE 3000 Series Carrier

Figure 3-10. Fan Module Installation

2.Place the fan module on the flanges (Figure 3-10) at the bottom of the carrier with the power connector facing the mating power connector on the installed power transformer unit. Slide the fan module into the carrier until the power connectors engage firmly.

3.If the carrier is connected to ac power, the fans in the fan module will begin blowing air when the power connectors are engaged. If the carrier is not powered at this time, then provide power to it.

If the fan module does not operate, check the fuses on the back of the power transformer unit (Figure 3-7). If the fuses are blown, replace the fuses and determine the cause of the overload. If the fuses are okay, install the fan module in

another powered carrier (if possible, one with a working fan module).

If the fan module still does not work, replace the fan module. If it works in a different carrier, replace the power transformer unit of the first carrier.

4.If you are not going to install an SDCP or speaker panel, reposition the cover plate over the installed fan module. Use the smaller screwdriver to engage and tighten the four captive screws.

If you are going to install an SDCP, proceed to the Shared Diagnostic Control Panel (SDCP) Installation procedure.

If you are going to install a speaker panel, proceed to the Speaker Panel Installation procedure.
