Indigo DT front panel hardware settings – cooling mode
The three modes are normal, quiet and maximum cooling.
The two-position DIL switch controls the three cooling modes as follows:
Piano Switches
Switches 1 and 2 configure the cooling fan modes.
Levers 1 & 2
Function
Notes
Both up
Normal
cooling
The fan runs continuously, increasing in speed as the
temperature inside the frame goes up.
1 down, 2 up
Quiet mode
For use with a lightly loaded frame for low ambient
temperature. When the frame temperature is below
approximately 45°C the fan is switched off. If the frame
temperature goes above 45°C it reverts to normal
cooling and goes back to quiet mode when frame
temperature falls below 42°C.
1 up, 2 down
Max cooling
mode
In Maximum cooling mode both fans never run below
near maximum speed. Fan speed increases to
maximum at high frame temperature. This mode is ideal
for equipment bays where noise is not a concern.
Both down
Reserved for
future use
Operates as normal mode with current software.
Note:
Quiet mode is dependent on the frame temperature being below 45°C and not
being in an alarm state.
Warning:
Although it is possible to operate the frame with the front panel open, the frame
may not meet electromagnetic compatibility (EMC) requirements in this
condition.
