3.9 System Cooling
Two replaceable 4cm fans provide the cooling for the system.
Make sure the chassis top cover makes a good seal so the cooling air circulates properly
through the chassis.
Figure 3-7. Fan Positions
Installing Fans
The E300-12C chassis includes two pre-installed fans. One additional open slot is available
so that one more fan may be added if additional cooling is required. These fans are NOT
redundant, hot-plug, and so must be replaced when they fail.
Replace any failed fan at your
earliest convenience with the same type and model (the system can continue to run with a
failed fan).
1. Power down the system as described in section 2.1 and remove the AC power cord and
the chassis cover.
2. Remove the wiring of the failed fan from the motherboard.
3. Remove the screws securing the fan to the chassis wall and save them.
4. Lift the fan out of the chassis.
5. Align the replacement fan with the holes in the wall of the chassis.
