Approved ANSI Standard

ANSI/VITA 46.11-2015

System Management on VPX

ABSTRACT

This document defines a framework for System Management in VPX systems. It enables

interoperability within the VPX ecosystem at the Field Replaceable Unit (FRU), chassis and

system levels. The framework is based on the Intelligent Platform Management Interface (IPMI)

specification and leverages many concepts and definitions from the AdvancedTCA

(ATCA

)

specification by PICMG

Approved: June 2015

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CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 standard by calling or writing the American National Standards Institute.

NOTE: The user’s attention is called to the possibility that compliance with this standard may require use

of an invention covered by patent rights.

By publication of this standard, no position is taken with respect to the validity of this claim or of any

patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to

grant a license under these rights on reasonable and nondiscriminatory terms and conditions to

applicants desiring to obtain such a license. Details may be obtained from the standards developer.
