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
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.

Normally right, no user function.

Default IP
address
Normally right. Left sets IP address to default
10.0.0.201. This default address is necessary to be able
to change the IP address during installation. See section
3
Normally right, no user function.
Note:
Quiet mode is dependent on PSUs and PSU fans not being in an alarm state.
If one of the fans should fail, the closed frame can still operate indefinitely with
an ambient temperature of up to 40°C.
Although only one of the fans is essential in normal operation, a faulty fan should
be replaced as soon as practical to prevent the long-term stressing of the
modules.
