6-3 System
Fans
Two 10-cm blower fans provide all the cooling needed for the 1020A-8. 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. See Figure 6-2.
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails,
the remaining fan 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 (see instructions on p. 6-8) while the system is
still running to determine which of the two fans has failed. Then power down the
system before replacing a fan. Removing the power cord(s) is also recommended
as a safety precaution.
Replacing System Fans
1.
Removing a fan
Remove the chassis cover. Detach the fan wires from their connection to the
serverboard. Remove the screws that secure the fan to the chassis and lift the
blower fan out.
2.
Installing a new fan
Replace the failed fan with an identical 10-cm, 12 volt fan (p/n FAN-0059). Install
the new fan in its proper place in the chassis by positioning it on the two mounting
posts. Secure the fan to the chassis with the screws you removed previously, then
attach the fan wires to the connector on the serverboard. Finish by replacing the
chassis cover and power cord and restoring power to the system.
