Fitting
1. Fit the fan assembly into the interior of the server enough to connect
the ribbon cable to the small power distribution board between the
middle and bottom fans. Ensure the clips are latched onto the
connector body.
2. Slide the assembly to the left into place and fasten it to the chassis by
means of four screws at the centre spine and five screws at the side.
3. Replace any card support struts across the motherboard.
Removing fan from assembly
These following instructions apply to all the fans in the server including any
described in other chapters.
Remove the four screws which hold the handguard onto the fan assembly
housing. This not only releases the handguard, but also the fan itself.

Caution Caution
Before attempting to fit the fan onto the fan assembly housing, be sure to place
the fan into the assembly so that the air flow through it is from the front of the
server to the rear (see the arrow next to the electrical polarity marking on one
corner of the fan). If any fan is turned the wrong way around, it will seriously
reduce the overall cooling effectiveness and increase the risk of overheating.
1. With the housing upright, align one corner of the handguard with a
screw hole and insert a screw just a few turns.
2. While holding the handguard and screw in place, align the fan to the
other holes and insert a second screw.
3. In a similar way, align and fit the remaining screws. Tighten when all
are in place. Do not overtighten or this may damage the fan housing.
