Removing a system fan

Use this information to remove a system fan in the server.
Read the safety information in "Safety" on page v and "Installation guidelines" on page 31.
If you are replacing a server component in the server, you need to slide the server out from the rack
enclosure, turn off the server and peripheral devices, and disconnect the power cords and all external cables.
Attention: Static electricity that is released to internal server components when the server is powered-on
might cause the server to halt, which might result in the loss of data. To avoid this potential problem,
always use an electrostatic-discharge wrist strap or other grounding system when you work inside the
server with the power on.
To remove a system fan, complete the following steps.
Step 1. Check the IMM2 event log to find out which fan needs to be replaced. Refer to Appendix A
"Integrated Management Module II (IMM2) error messages" on page 283 for the error messages.
Step 2. Remove the cover (see "Removing the cover" on page 157).
Step 3. Remove the air baffle if installed (see "Removing the air baffle" on page 159).
Step 4. Remove the failed fan from the server:
a. Disconnect the fan cable from the system board. Note the routing of the fan cable to the
connector; you will have to route the fan cable the same way when you install the fan.
b. Grasp the top of the fan with your index finger and thumb and lift the fan out of the server.
