VPX4812A/4814A
User’s Manual
Single-Slot 3U VPX Bus XMC Carrier Card/Switch Card Module

The VPX4812A also conforms to OpenVPX peripheral module profile MOD3-PER-1F-14.3.2 when
used as an XMC carrier card. Typically, this peripheral profile can be used in a wide range of
OpenVPX backplane profiles but due to the PCIe switch connections on P1, the VPX4812A may
be incompatible with profiles that contain other plane interfaces on P1. Check the VPX
connector pinout in this manual against the intended backplane topology to ensure
compatibility.
The VPX4814A disconnects the lower four PCIe lanes on P1 while retaining all of the XMC carrier
card functionality of the VPX4812A. This allows it to be used as an XMC carrier card in a wider
range of OpenVPX backplane profiles including profiles that contain Ethernet control plane
interfaces on P1.
Build Levels
The VPX4812A/14A is available in three electrically compatible build levels, each of which is
carefully tailored to a particular set of requirements and environments. All three levels fully
support the power and versatility of VPX, so no matter how large or diversified your project,
absolute compatibility is assured at all stages of development. The three build levels have three
basic mechanical configurations, both in accordance with the VITA 46.0 VPX standard and the
VITA 48 REDI standard:
1.
Air (convection) cooled modules are intended for use in standard industrial chassis.
2.
Conduction-cooled modules are intended for use in sealed Air Transportable Racking
(ATR) and other conduction-cooled environments.
3.
REDI cover, Conduction-cooled modules are intended for use in sealed Air Transportable
Racking (ATR) and other conduction-cooled environments.
