System Fans

Three 8-cm hot-swap chassis fans provide the cooling for the SuperServer 2027R-
E1R24L. It is very important that the chassis top cover is properly installed in order
for the cooling air to circulate properly through the chassis and cool the components.
See Figure 6-3.
System Fan Failure
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining
fans will ramp up to full speed and the overheat/fan fail LED on the control panel will
turn on. Replace any failed fan at your earliest convenience with the same type and
model (the system can continue to run with a failed fan). Remove the top chassis
cover while the system is still running to determine which of the fans has failed.
Replacing System Fans
Replacing a System Fan
1. If necessary, open the chassis while the power is running to determine which
fan requires changing. (Never run the server for an extended period of time
with the chassis open.)
2. Press the fan release tab to lift the failed fan from the chassis and pull it
completely out of the chassis.
3. 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.
4. The fan will automatically begin running at the correct speed.
