Approved American National Standard

ANSI/VITA 65-2010

OpenVPX™ System Specification

Abstract

The OpenVPX System Specification was created to bring versatile system architectural

solutions to the VPX market. Based on the extremely flexible VPX family of standards, the

OpenVPX standard uses module mechanical, connectors, thermal, communications protocols,

utility, and power definitions provided by specific VPX standards and then describes a series

of standard profiles that define slots, backplanes, modules, and Standard Development

Chassis.

Approved June 2010

American National Standards Institute, Inc.

American

National

Standard

Approval of an American National Standard requires verification

by ANSI that the requirements for due process, consensus, and

other criteria for approval have been met by the standards

developer.

Consensus is established when, in the judgment of the ANSI Board

of Standards Review, substantial agreement has been reached by

directly and materially affected interests. Substantial agreement

means much more than a simple majority, but not necessarily

unanimity. Consensus requires that all views and objections be

considered, and that a concerted effort be made toward their

resolution.

The use of American National Standards is completely voluntary;

their existence does not in any respect preclude anyone, whether

he has approved the standards or not, from manufacturing,

marketing, purchasing, or using products, processes, or procedures

not conforming to the standards.

The American National Standards Institute does not develop

standards and will in no circumstances give an interpretation of

any American National Standard. Moreover, no person shall have

the right or authority to issue an interpretation of an American

National Standard in the name of the American National Standard

Institute. Requests for interpretations should be addressed to the

secretariat or sponsor whose name appears on the title page of this

standard.

CAUTION NOTICE: This American National Standard may be

revised or withdrawn at any time. The procedures of the American

National Standards Institute require that action be taken

periodically to reaffirm, revise, or withdraw this standard.

Purchases of American National Standards may receive current

information on all standards by calling or writing the American

National Standards Institute.
