RMC 7132
1U Rackmount System
6-3 System Fans
Two 10-cm blower fans provide the cooling for the Acnodes RMC7132. The chassis includes air
seals under the blower fans and at the chassis cross section, which separates the drive bay area
from the serverboard area of the chassis to promote better airflow. It is highly important that the air
seal is properly installed and making a good seal in order for the cooling air to circulate properly
through the chassis.
The fans can adjust their speed according to the heat level sensed in the system, which results in
more efficient and quieter fan operation. Fan speed is controlled by a setting in BIOS (see Chapter
7).
System Fan Failure
If a fan fails, the ambient air temperature in the chassis will rise and activate the overheat LED on
the control panel. You will need to power down the system to replace this fan with one of the same
type (p/n FAN-0038L4). Contact your vendor or Supermicro for information on replacement fans.
Replacing System Cooling Fans
1. Turn off the power to the system and remove the AC power cord.
2. Remove the chassis cover and unplug the fan cable from the serverboard
3. Unscrew the failed blower fan from the chassis and pull it completely out from the serverboard.
4. Replace the failed fan with an identical 10-cm, 12 volt fan. Position the new fan in its proper
place and secure it to the chassis with the screws you re- moved previously.
5. After the new fan has been installed, plug the fan cable back into the same chassis fan header on
the serverboard you removed it from.
6. Reconnect the AC power cord and power up the system.
7. Check that the fan is working properly and that the overheat LED on the control panel has turned
off.
8. Finish by replacing the top panel of the chassis.
