Figure 5-14. Chassis Fans
The SC116 chassis includes four pre-installed fans. Two additional open slots are
available so that up to two more fans may be added if additional cooling is required.
Replacing a System Fan
1. If necessary, open the chassis while the power is running to determine which
fan has failed. Never run the server for an extended period of time with the
chassis open.
2. Power down the system and remove the power cords from the rear of the
power supplies. Remove the chassis cover as described in Section 5-3.
3. Remove the failed fan's power cord from the serverboard.
4. Lift the failed fan from the chassis and pull it completely out from the
serverboard.
5. 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.
6. Reconnect the fan wires to the exact same chassis fan headers as the previ-
ous fan.
7. Plug the power cords into the rear of the power supplies, power up the sys-
tem and check that the fan is working properly before replacing the chassis
cover.
