Piano Switch
Switches 1 and 2 configure the cooling fan modes.
Levers 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
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.
Levers 3 & 4
Function
Notes
3
Debug
Normally up, no user function.
4
Default IP
address
Normally up. Down sets IP address to default 10.0.0.201.
Note:
Quiet mode is dependent on PSU 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.
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.
Switch 3 is for debug purposes and should normally be left in the up position.
Default IP address
Switch 4 in the down position sets the active front panel to the default IP address of
10.0.0.201. This default address is necessary to be able to change the IP address during
installation.
PSU Configuration
PSU configuration only applies to the 2U and 4U frames where it is possible to have
multiple power supplies fitted into a single frame. Should a power supply not be fitted in
either the upper or lower slots of the 2U frame or the upper or lower slots of the lower
section of the 4U frame the position of the two-position slide switch must be set
accordingly.
