Replacing system fans
This server contains two groups of hot-swappable fans (seated in fan cages) and
a fan board, which are located inside the chassis. The first group of fans is in
front of the processors and contains six fans in three dual-fan assemblies. The
second group of fans is in front of the power supply, and contains two fans.
These fans maintain the ideal temperature for the system board, backplane, and
disk drives. If one fan fails, the speed of the other fans will increase. With the
bad one replaced, the other fans may revert to the normal speed.
To replace a system fan:
1 Follow the instructions in “Preventing static electricity discharge” on
page 30.
2 Follow the instructions in “Opening the server case” on page 31.
3 Determine which fan group needs to be replaced by noting which fans
are not operating.
Important
Make sure that the arrows on top of the
fans indicating airflow point to the back
of the chassis. The fan cable should exit
the fan module toward the back of the
chassis.
4 Pull up the locking handle (4) on the system fan, then lift the fan group (5)
from the fan cage in the chassis.
5 Insert the replacement fan group into the fan cage and press down the
locking handle to secure the fan group in place.
6 Follow the instructions in “Closing the server case” on page 32.
To replace the system fans and the fan cage:
Important
Both system fan cages are replaced in a
similar manner.
1 Follow the instructions in “Preventing static electricity discharge” on
page 30. Make sure that you turn off the server, then unplug the power
cord(s) and all other cables connected to the server.
2 Follow the instructions in “Opening the server case” on page 31.
