6-5 System Fans
One 12-cm chassis cooling fan provides air intake while another 12-cm exhaust fan
expels hot air from the chassis. Both are low-noise fans that result in "Whisper-Quiet"
operation (~28 dB). The fans should be connected to headers on the motherboard
(see Chapter 5).
The power supply includes redundant cooling fans. If one fan fails, the remaining
fan will ramp up its rpm to provide sufficient cooling. The Power Fail LED will il -
luminate and an audible alarm will sound, which can be silenced with a button on
the power supply. If a power supply fan fails, you should replace the power supply
at your earliest convenience.
Fan Failure
Under normal operation, the chassis fans, the exhaust fan and the power supply
fans run continuously. The chassis fans are hot-pluggable and can be replaced
without powering down the system.
Replacing Chassis Cooling Fans
Removing a Fan
1. First locate the failed chassis fan by removing the top/left chassis cover (see
Chapter 2 for details). Locate the fan that has stopped working.
2. Disconnect the power cord to the chassis and disconnect the cable to the fan.
3. Remove the two screws securing the fan bracket to the chassis.
4. Remove the four screws securing the fan to the fan bracket.
5. Lift the fan up and out of the chassis.
Installing a New Fan
1. Replace the failed fan with an identical one (available from Supermicro)
2. Secur the fan to the bracket with four screws and secure the bracket to the
chassis with two screws.
3. Install it in the same position and orientation as the one you removed.
4. Check that the fan is working then replace the chassis cover.
