Power interface boards come in multiple configurations

PIXUS TECHNOLOGIES VITA 62 power supplies are available in multiple configurations for use in many rugged OpenVPX applications. The Power Interface Boards (PIB) come in 3U and 6U heights in either single PSU or dual PSU formats. Products have a header for the voltage sense and IPMB for VITA 46.11 system management or other IPMI-based options. Devices have several power bugs for 3.3V, 5V, and 12V power. A 26-pin header accommodates all of the general purpose IO signals from the PSUs.  http://www.pixustechnologies.com
