3.8 System Cooling
Fans
Six 6-cm heavy-duty fans provide cooling for the system. Fans are hot-swapped and can
be replaced without powering down the system. The electrical connections are automatically
made when a fan is inserted into its slot.
Make sure the chassis cover is only off for a short time and makes a good seal when replaced
for the cooling air to circulate properly through the system.
Changing a System Fan
1. Determine which fan is failing using BMC if possible. If not, remove the chassis cover
while the power is on and examine the fans to determine which one has failed.
2. Pull the system partially out from the rack.
3. With the top cover partially pushed back, depress the release buttons on the front
section of the top cover to swing it open on its hinges.
4. Squeeze the fan tabs of the failed fan and lift the fan housing up and out of the chassis.
5. To install a fan, push it into the proper location until it clicks.
6. Finish by fully closing the cover and pushing the system back into the rack.
