Installation
IMPORTANT: The VPX4812 has been specifically design for use with 3U VPX backplanes and my not be
compatible with some 6U backplanes. Plugging the board into an unsupported 6U VPX backplane may
cause permanent damage.
Consult the enclosure documentation to ensure that the
VPX4812’s
power requirements are compatible
with those supplied by the backplane.
Board Keying
The 3U VPX backplane specification requires all backplane slots
to have two guide pins: one above the J0 connector and one
below the J2 connector. As well as providing correct alignment,
these pins are keyed to prevent cards from being inserted into
incorrect backplane slot(s) to avoid electrical incompatibility.
The VPX4812 has
receptacles for these guide pins (see the
Connectors section). By default, these are not keyed. Please
contact the factory to discuss keying requirements.
Installation Notes
1.
Keying may dictate the backplane slot(s) into which the
VPX4812 can be inserted.
2.
Air-cooled versions have an ejector handle to ensure that
the backplane connectors mate properly with the
backplane. The captive screws at the top and bottom of the
front panel allow the VPX4812 to be tightly secured in
position, which provides continuity with system chassis
ground.
3.
Conduction-cooled and REDI versions have screw driven
wedge locks at the top and bottom of the board to provide
the necessary mechanical/thermal interface. Correct
adjustment requires a calibrated torque wrench set to
between 0.6 and 0.8 Nm.
