Chapter 3: Maintenance and Component Installation
System Cooling
Three 8-cm hot-swap chassis fans provide the cooling for the AS-2113S-WN24RT. It is very
important that the top cover of the chassis is properly installed in order for the cooling air to
circulate properly through the chassis and cool the components.
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 a System Fan
1. Press the release tab to lift the failed fan and pull it completely out of the chassis.
2. 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 direction as those on the
other fans. The fan will automatically begin running at the correct speed.
