Chapter 6: Advanced Chassis Setup

6-3

Fan Conﬁ guration

In the 2U Twin

, each node (serverboard) controls the two fans that reside on its

side of the chassis. If the fan speed settings in BIOS are set to different values for

each two node, the BIOS setting with the higher fan speed will apply to both. In the

event that one of the serverboard drawers is removed, then the remaining node/

serverboard will operate both fans.

Note: Due to this conﬁ guration, both nodes on the same side of the chassis as the

failed fan must be powered down before replacing the fan.

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

If necessary, open the chassis while the power is running to determine which 1.

fan has failed. (Never run the server for an extended period of time with the

chassis cover open.)

Remove the failed fan's wiring from the backplane.2.

Lift the fan housing up and out of the chassis.3.

Push the fan up from the bottom and out of the top of the housing.4.

Place the replacement fan into the vacant space in the housing while making 5.

sure the arrows on the top of the fan (indicating air direction) point in the

same direction as the arrows on the other fans.

Conﬁ rm that the fan is working properly before replacing the chassis cover.6.
