•
This monolithic backplane has 2 segments of H.110 bus. One
H.110 bus exists on slots #2 through #8. The other H.110 bus
exists on slots #10 through #16.
•
The backplane includes two standard fabric slots (#17 and
#18) according to PICMG 2.16 and two 8-slot cPCI bus
segments, each with one system slot (#1 and #9) and seven
peripheral slots. The system and peripheral slots are standard
dual nodes according to PICMG 2.16.
2.2.4.1 cPCI Backplane
•
The cPCI backplane includes two independent segments of 8-
slot cPCI connectors.
•
The cPCI backplane includes power supply connectors to the
power supply modules (47 pin connector to each module) and
power distribution to all slots.
•
DC main input to the power supply section of the backplane is
be through the DC Input module system.
•
The cPCI backplane provides a connector behind the Power
Supply section for the purpose of connecting a stand-alone
CMC (Chassis Management Controller) board.
•
The cPCI backplane incorporates six sets of fan control
signals, originating on the CMC connector. Each set of fan
control signals includes: FANTACH or LKROTOR, 12VDC
(PWM), GND.
•
The cPCI backplane incorporates a continuous IPMB0 bus
from the CMC connector to all 18 cPCI slots.
•
The cPCI backplane provides local I2C bus from the CMC
connector pins to two locations in the upper portion of the
backplane and one location in the lower left corner of the
backplane for the purpose of connecting I2C sensor
components at strategic locations within the enclosure.
2.2.4.2 Backplane CMC Connector
•
Chassis Management Controller (CMC) is optional to the
system enclosure.
