Removing a system fan

Use this information to remove a system fan in the server.
Read the safety information in "Safety" on page iii and "Installation guidelines" on page 79.
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. Turn off the server (see "Turning off the server" on page 23 for instructions) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external cables from the
server.
Step 2. Remove the fan cage cover (see "Removing the fan cage cover" on page 86).
