COMSPHERE 3000 Series Carrier
3-16 December 1994 3000-A2-GA31-80
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.
