Introduction
The VITA62 3U evaluation platform described in this document is primarily designed to be used with the
following power supplies.
1.
VIT028x3U600y000
2.
VIT270wxx600yzzz
3.
SOS028x3U800y000
The focus of this document is to assist the user in using the evaluation platform with 3U form factor
VITA62 and SOSA™-aligned power supplies.
It is important to remember that power supplies evaluated with this test platform have no means of
cooling other than through natural convection. If power supplies are left powered on for extended
periods of time, they will overheat. It is recommended to use forced-air cooling aimed at the heat sink
of the power supply to provide active forced cooling when the unit is powered on.
(requires removal of guide pin KM1)
