Captive screw

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

prompt 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.
