24 CT-100C Installation
FAN SPEED SWITCH
A fan speed selector switch is located at the rear of the CT-100C chassis. To set the fans to
operate at HIGH speed, move the switch at the rear of the chassis to the left. At HIGH speed, the
chassis is provided maximum cooling to the instruments.
The fans will operate in the LOW speed mode when the fan speed switch is toggled to the right.
The low speed mode provides for quieter operation, but decreases the cooling capability of the
fans. To best determine which mode of operation is best in a given application, refer to
Figure 1-6
on page
19 that delineates the cooling requirements of populated mainframes. If all instruments
installed in the chassis receive adequate cooling in the low speed mode, then this mode may be
used.
