6-3 System Fans

Two 8-cm PWM chassis fans provide air intake while one 9-cm PWM exhaust fan expels hot air from the chassis. All are low-noise fans that result in "Whisper-Quiet" operation (~28 dB). The fans should be connected to headers on the serverboard (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.Depress the locking tab on the failed fan: on a chassis fan, push the tab on the side of the housing inward, on the exhaust fan push down on the colored tab.

3.With the tab depressed, pull the unit straight out (see Figure 6-3). The wiring for these fans has been designed to detach automatically.

Installing a New Fan

1.Replace the failed fan with an identical one (available from Supermicro)

2.Install it in the same position and orientation as the one you removed; it should click into place when fully inserted.

3.Check that the fan is working then replace the top/left side chassis panel.
