DIP Switches
The backplane has a DIP switch that may be used to control chassis behavior.
DIP switch #1 (first from the bottom) controls the chassis fan mode. When this switch is in the
off (right) position, Auto mode is selected. When this switch is in the on (left) position, High
mode is selected.
DIP switch #2 (second from the bottom) controls the chassis Inhibit Mode. When this switch is
in the off (right) position, Default mode is selected. When this switch is in the on (left)
position, Manual mode is selected.
