Press Release

September 30, 2021

VITA is accepting registrations to be a member of a public review VITA Consensus Body for voting to revise this standard. You do not have to be a VITA member to participate in this Consensus Body. The response deadline to register for this consensus body is: October 5, 2021

REVISION OF EXISTING STANDARD Under ANSI and VITA rules every 5 years an approved standard must be reaffirmed, revised, placed in stabilized maintenance or withdrawn. This standard has been revised, hence it has been put forth for approval of the revisions.

DRAFT/VITA 48.0-2021x: Mechanical Standard for Microcomputers using Ruggedized Enhanced Design Implementation (REDI)

Abstract: This standard defines a mechanical implementation for Plug-In Modules. Two types of Plug-In Modules are defined: Type 1 and Type 2. Both Type 1 and Type 2 Plug-In Modules take advantage of increased slot pitch to provide enhanced thermal performance and increased structural durability. Type 1 units support Two Level Maintenance while Type 2 units do not. This revision adds allowance for a 100 mm Plug-In Module depth and allows for additional pitches to be defined in the VITA 48 Dot Standards.

DRAFT/VITA 48.2-2021x: Mechanical Standard for Microcomputers using Ruggedized Enhanced Design Implementation (REDI)

Abstract: This standard defines the mechanical requirements that are needed to ensure the mechanical interchangeability of conduction cooled 3U and 6U Plug-In Modules and defines the features required to achieve Two Level Maintenance compatibility. This revision adds a 100 mm depth and multiple pitches at 0.2" increments.

Stakeholders: Anyone building or using VPX boards or systems in enhanced environments.

HOW TO APPLY FOR THE CONSENSUS BODY Currently, this consensus body needs voting members from the following interest categories in order to be able to proceed with this process.
