3.5.4 Fan Module Connector (FAN1~4)
The FAN connectors FAN 1~4 p12 V power for fan operation and accepts the
tachometer output from the fans.
3.6 Clock Routing Configuration
The backplane is configured to comply with the clock routing specified in the
CompactPCI™ Hot Swap Specification, PICMG 2.1, R2.0. This Specification requires
that each slot be independently clocked.
If users would like to reconfigure the backplane to comply with the earlier
CompactPCI™
Specification, PICMG 2.0, version 3.0, which allows the backplane to
be backward compatible with CPUs using shared clocks, please contact Advantech
for help.
