This topic provides instructions on how to replace a system fan. Your server has three system fans.
Note: This procedure must be performed only by trained service personnel of Lenovo.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Ensure that the new system fan is the same type with the system fan that you want to replace.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
To replace a system fan, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface.
3. Remove the server cover. See “Removing the server cover” on page 55.
4. Locate the system fan that you want to replace. See “Server components” on page 17.
5. Disconnect the system fan cable from the system board. See “System board components” on page 32.
Note: If you want to replace the system fan 1 that is near the rear of the server, remove the riser card
assembly to access the system fan 1 connector on the system board. See “Replacing the riser card
assembly” on page 75.
