Fan-and-Power-Supply Assemblies

Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104
Model TU3 are two fan-and-power-supply assemblies.

Each fan-and-power-supply assembly provides enough power for the 2104, so it is
possible for there to be just one fan-and-power-supply assembly in a 2104. The second
fan-and-power-supply assembly is replaced by a fan assembly. The
fan-and-power-supply assembly provides the power for the fan assembly via the 2104
backplane.
