Chapter 11 Replacing a Server or Replacing Individual Components 11-19
11.8 Replacing the Rear Fan Subassembly
(Fans 1 and 2)
Caution – The procedure below is for the attention of qualified service engineers
only. Before touching or replacing any components inside the server, disconnect all
cables and follow the instructions in Section 4.2, “Opening the Server” on page 4-4
which tell you how to open the server. Always place the server on a grounded ESD
pad and wear a properly grounded antistatic wrist strap.
1. Open the server by following the instructions in Section 4.2, “Opening the
Server” on page 4-4.
Make sure you disconnect all external cables and pay particular attention to the
information about how to prevent electro-static discharge from your body from
damaging the components of the server.
2. With the server open and seated on top of an ESD pad, and with a properly
grounded antistatic wrist strap on your wrist, disconnect the old subassembly’s
power cables from the system board (see
FIGURE 11-10).
3. Lift out the old subassembly and discard it.
4. Insert the new fan subassembly into its bay in the chassis.
5. Connect the fan cables to the system board (see
FIGURE 11-10).
6. Replace the server’s cover and tighten the captive screw (see
FIGURE 4-9 in
Section 4.7, “Replacing the Server’s Top Cover” on page 4-14).
