The fan speed is controlled by the CMM depending on a fan curve stored in a CMM register. 16 fan curves are available as shown in Figure 3.5, the default fan curve is '5'. Figure 3.5- 42-924 Chassis Fan Speed/Temperature Curves Maximum Cooling For maximum cooling performance, set the fan speed switch at the chassis rear side to “MAX“.
The input current of the chassis is limited to 10A. This results in an available PSU output power at the following nominal AC input voltages: • 100V --> 500W • 115V --> 580W • 230V --> 600W Figure 3.6- 42-924 Chassis Power Supply Output De-rating Curve PXIe 8-SLOT FULL HYBRID CHASSIS 42-924 Page 3.6...

SECTION 4 - CHASSIS MANAGEMENT MODULE CHASSIS STATUS LEDS The 42-924 management system monitors the internal chassis temperature and varies the fan speed accordingly. The system also monitors the power supply’s voltage rails and speed of the fans and indicates the chassis’ status on the front panel LEDs built in to the power switch.
Note: Due to address range limitation by PXIe spec, a setting of ADD0 = ADD1 = open leads to address 5Ch. Same address as with settings ADD0 = GND, ADD1 = open. PXIe 8-SLOT FULL HYBRID CHASSIS 42-924 Page 4.2...
