Generally, the fan module delivered has already been
mounted with hangers. If not, you can install the hangers
first according to Step 1 above for the installation of the 10U
chassis.
The fan module contains six DC fans that weigh about 3 kg. To make the replacement and cleaning of the fans
much easier, the fan module of 3P@C 4450E is designed to be dismountable. As shown in Figure 4-25, a puller
adapter is designed in the front face of the fan module. This puller adapter is closed when not in use. When it is
needed to dismount, replace or clean the fans, please operate this puller adapter with both hands.
Step 1 Wear the antistatic wrist strap and insert its plug into the ESD
socket in the front face of the 19-inch cabinet 2.2 m high.
Step 2 Cut off the system power supply of 3P@C 4450E before inspecting
the fan module for a long while (more than 5 minutes).
Step 3 Loosen the fastening screws at the two sides of the fan module
with a screwdriver.
Step 4 Press down the white left end of the puller adapter in the middle of
the fan module panel. The puller adapter will automatically eject
out, as shown in Figure 4-25.
