SC523 Chassis Manual
5-14
The SC523 chassis includes two fans for cooling and air circulation.
5-9 System Fans
Replacing a System Fan
If necessary, open the chassis while the power is running to determine which
fan needs replacing. (Never run the server for an extended period of time with
the chassis open.)
Turn off the power to the system and unplug the system from the outlet.
Remove the hard drive tray and DVD or CD-ROM drive. For instructions on
removing these drives, see the section titled Removing and Installing the DVD
or CD-ROM Drive in this manual
Disconnect the system fan from the motherboard and lift the fan from the fan
tray.
Place the new fan into the vacant space in the housing while making sure the
arrows on the top of the fan (indicating air direction) point in the same direc-
tion as the arrows on the other fans. Each fan includes rubber feet to reduce
vibrations. Always use all four feet when placing a system fan.
Connect the new fan to the motherboard.
