The following figure illustrates the basic power supply logic implemented on your BoC.

EVM Power Source [16, 17, 18]
Traditionally the EVM’s installed into the Boc will have there own power supplies. There
may be on occasion where a user needs to power both boards from the same power
source. The BoC contains three mounting holes (for banana jacks) that when installed
can be used to power the EVM’s installed.
EVM’s vary in total board power requirements. The power rating based on the current
designed layout of your BoC card will accommodate up to 8 amperes per board.
The recommended banana jacks to be installed are manufactured by Pomona®, part
numbers:
•
1581-2 (Red, 2 required)
[17 & 18]
•
1581-0 (Black, 1 required)
[16]
The mounting pads on the BoC are electrically conductive. Due to the height limitations
and the need to clear any supporting surface, the bottom insulated ring must be placed on
the top side of the PCB and the star washer and nut assembled from the bottom.

CAUTION
: If you elect to power your EVM’s through the BoC card, you
MUST not use power supplies connected to your EVM’s input power.
WARNING
: If you elect to power your EVM’s in this method, your EVM
power requirements must not exceed the maximum power allowed by the
design.
