Backplane 2.0 to BB2 PSU Harness

(1/1)

Eddiie:
If you happen to be in a situation where you have a Backplane 2.0 and no power harness to go from the BB2 PSU to the backplane, then this should help you.

The 24v line from the BB2 PSU would go to its own jumper on the old BB backplane.   On the Backplane 2.0 it is part of the big 22 pin harness.
You will need to modify any BB1 / BB2 / BB3 power harness for use on the Backplane 2.0.

The 5vi line uses all 4 wires on the backplane 2.0, whereas they one used 2 pins on the old backplane.

As a reminder, the latch on these molex plugs are below the BOTTOM row of pins and pin numbering starts at top-left, goes across, then wraps to the next row..

The pins are looked at from the wire perspective, going into the connector.   Top-left, pin 1.
The list below, pins on the left are the BB2 PSU, the destination pins are the pins on the Backplane 2.0

2  - BP J33 Pin 13
3  - BP J33 Pin 1
4  - BP J33 Pin 2

5Vi P6
4 Pin (1 x 4 pins)
1  - BP J19 Pin 1 ISO 5v  +
2  - BP J19 Pin 2 ISO 5v  -
3  - BP J33 Pin 14   New wire
4  - BP J33 Pin 3     New wire


If you want to make or bypass the power switch, that is P2 on the PSU,  PIns 1 and 14 connect together and pins 5 and 10 connect together to make the psu come on.  typical power switch will toggle both sides of the connection, so pin 1 and 5 would go on one side / pole of the switch and 5 and 10 would go on the other side / pole of the switch.  Do at your own risk.  :)
