If the fans are piggy-backed, the back fan connects directly to a power supply connector
through a patch connector.
If the fans are side by side, then both fans are connected on the SSM board. Fan wires run
under the power supply and are connected to J7 or J6 on the SSM board, as shown in
Figure 112.
