Reaffirmation of Approved Standard

Therefore, the VSO by ballot has recommended that this standard be reaffirmed.
Consensus body registration for voting on reaffirmation of this approved standard is now open.
ANSI/VITA 48.8-2017 - Mechanical Standard for VPX REDI Air Flow Through Cooling, 1.0" to 1.5" Pitches
Abstract: This document describes an open standard for the design requirements for an air-flow through cooled plug-in module having 3U and 6U form factors while retaining the VITA 46.0 connector layout. Unlike using cooling air impinged directly upon the components and circuit boards, this plug-in module uses a finned heat exchanger frame located within the central section of the assembly to top cool primary circuit board components as well as mezzanine board components. Both 3U and 6U standard form factors are offered using 3 defined pitch spacings, with options to have alternate air flow intake and exhaust paths. The plug-in modules of this standard exhibit a weight reduction and cost savings by eliminating both wedge retainer usage and module lever usage by way of using light weight jack screws for plug-in module insertion and extraction into a subrack chassis. The intention of this standard is to optimize SWAP-C (Size, Weight, Power, Cost).
