R
Power Supply Module
The power supply module supplies all voltages shown in
Table 3, page 15
to the DUT
RocketIO transceivers. This module plugs in on the right side of the board on header J134,
J133, and J26 of the ML52x platform.
The onboard regulators also have corresponding input voltage jacks to supply each
voltage independently from a bench-top power supply. This is done by installing the
power supply disable jumpers for the headers that correspond to each supply voltage
