Fan Confi guration
In the 2U Twin, each node (serverboard) controls the two fans that reside on its
side of the chassis. This means that two nodes will share control for two fans. If the
fan speed settings in BIOS are different for these two nodes, the BIOS setting with
the higher fan speed will apply. 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 befi re
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 up and out of the chassis.
4.
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.
5.
Confi rm that the fan is working properly before replacing the chassis cover.
