Figure 37 shows an illustration of the inside of a fan control
enclosure. Displays with line receivers and data distributors
both have fan controller enclosures. The components in this
enclosure are responsible for monitoring the cooling fans and
sending information about the fan status to the display
controller.
Refer to Section 4.10 for details and a close-up view of the
connections in the fan controller enclosure.
Connecting the Line Receiver to the Fan
Controller Enclosure
In displays with a line receiver, the connection from the
line receiver to the fan controller enclosure is completed
at the factory. Multiple fan controllers can be
interconnected together. Refer to the System Riser
Diagram in Appendix B or the System Overview
Manual, if present, for details.
Connecting the Data Distributor to the Fan Controller Enclosure
In displays with a data distributor, the fan control enclosure must be connected to the fan controller
expander card in the data distributor. Figure 38 shows a close-up view of a fan controller
expander card in the data distributor. Multiple fan controllers can be interconnected together.
Refer to the System Riser Diagram in Appendix B or the System Overview Manual, if
