6-3 System Fans
Four 8-cm fans provide all the cooling needed for the SuperServer 6021i.
Only three chassis fans operate in the normal condition, as the fourth fan
is a hot stand-by over heat fan which operates only upon the failure of
on of the three chassis fans. 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. See Figure 6-3.
System Fan Failure
The fans run at 3400 rpm. If a fan fails, the ambient air temperature in
the chassis will rise and activate the overheat LED on the control panel.
Replace any failed fan immediately. The hot plug fans will start to
function upon connection to its fan header on the P3TDDE motherboard.
Replacing System Cooling Fans
1. Removing a fan:
Remove the chassis cover. Press the tabs on the top of the fan housing
and remove the fan and its housing. The system power need not be shut
down since the fans are all hot-pluggable on the P3TDDE motherboard.
2. Installing a new fan:
Replace the failed fan with an identical 8-CM, 12 volt fan (available from
Supermicro). Position the new fan at its proper place in the chassis, by
fitting the fan with its housing onto the fan mounts in the chassis. A
"click" can be heard if the fan in its housing is properly installed. If the
system power is on, the fan will start immediately upon being connected
to its header on the P3TDDE motherboard, with its hot-changeable fan
feature.
