Chapter 6: Advanced Chassis Setup
Fan Configuration
In the 2U Twin, each node (serverboard) controls the two fans that reside on its side of the chassis.
System Fan Failure
If a fan fails, the remaining fans will ramp up to full speed and the overheat/fan fail LED on the control panel will blink on and off (about once per second). Replace any failed fan at your earliest convenience with the same type and model. See note above about powering down the nodes associated with the failed fan before replacing.
Changing a System Fan
1.If necessary, open the chassis while the power is running to determine which fan has failed. (Never run the server for an extended period of time with the chassis cover open.)
2.Remove the failed fan's wiring from the backplane.
3.Lift the fan housing up and out of the chassis.
4.Push the fan up from the bottom and out of the top of the housing.
5.Place the replacement fan into the vacant space in the housing while making sure the arrows on the top of the fan (indicating air direction) point in the same direction as the arrows on the other fans.
6.Confirm that the fan is working properly before replacing the chassis cover.
