CPCI Backplane PD11: CP6-BP8-P47-STD

5.2 Fan Connectors

The backplane is equipped with four connectors for supplying power for fan(s) and for con-

necting a fan speed control device. JP21/23 (FAN1/2), are 3-contact male connectors which

supply +12V for fan operation as well as the possibility to connect to a speed control device

for regulating air flow within the system sub-rack. JP22/24 (NTC1/2), are 2-contact male con-

nectors which provide a separate connection for a speed control device and are designed to

be used in conjunction with JP21/23.

For fans that have their own speed control or where no control is required, pins 1 and 2 of

JP21/23 can be used. For external speed control of fans, pins 2 and 3 of JP21/23 and pins 1

and 2 of JP22/24 are used. Pin 3 of JP21/23 and pin 2 of JP22/24 are connected internally on

the board side to each other.

External air flow regulation can be accomplished using a negative thermal coefficient (NTC)

device connected to JP22/24
