Cooling mode
Switches 1 and 2 of the four-position DIL switch control the three cooling modes - normal, quiet
and maximum - as follows:
Switch 1 & 2 Function
Notes
Both up
Normal cooling
Both fans run 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 panel fan is switched off
and the PSU fan runs at minimum speed. 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
Maximum
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 PSUs and PSU fans not being in an alarm state.
For the Indigo 2SE only one of the fans is essential in normal operation and if
one of the fans should fail, the closed frame can still operate indefinitely with an
ambient temperature of 40°C.
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.
