3. Unlatch the fan assembly from the chassis frame by pressing UP on the latch located
at the bottom center of the fan housing. While pressing on the latch, grasp the handle
and pull the lower portion of the fan housing towards you to disconnect the housing
from the midplane connector, and to clear the chassis frame. Once the lower portion
of the housing is clear of the frame, pull the fan housing slightly downward to allow
the two mounting tabs, located at the top of the fan housing, to clear the mounting
holes in the top frame of the chassis.
Installing an upper fan assembly
1. Remove the new upper fan assembly from its packaging, and position the new fan
assembly with the handle and locking latch facing downward.
2. Position and guide the the top portion of the fan assembly into the chassis frame so
that the mounting tabs at the top of the fan housing slide into the two mounting holes
in the top frame of the chassis.
3. Press the locking latch UP and using the handle, push the lower portion of the fan
assembly housing into the lower portion of the frame, making sure that the fan
assembly connector mates with the corresponding midplane fan connector. The fan
assembly will start operating immediately and the Fan Status LED will be lit green.
4. Release the latch to lock the fan assembly into place in the chassis frame.

Attention: Refer to safety notices before starting an installation.
Attention: Do not turn AC power off to remove, replace, or install a fan
assembly. Fan replacement must not be delayed. Increased heating inside the
chassis will occur due to reduced system cooling whenever a fan assembly is
not present.
