1.
Grasp the two handles on either side and pull the unit straight out until it locks (you will hear
a "click").
2. Next, depress the two buttons on the top of the chassis to release the top cover and at the
same time, push the cover away from you until it stops. You can then lift the top cover from
the chassis to gain full access to the inside of the server.
Note: Normally you would power down the system before installing or removing internal
components - but it may be necessary to leave system power on to determine which fan has failed.
Five 8-cm hot-swap fans provide the cooling for the system. It is very important that the chassis
top cover is properly installed and making a good seal in order for the cooling air to circulate
properly through the chassis and cool the components.
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will flash. Replace
any failed fan as soon as possible 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. After determining which is the failed fan, remove power from the
system by unplugging the server's cord.
This section describes how to remove or install a system fan.
