► Hardware
The Linear Feed Card is a replacement for PSAs (which are no longer in production) for 72-HP subracks. It simply provides a pair of front-panel circular power connectors which connect to the Winchester MRA-34P-G power connector on the back plane. See MCE Power Requirements for details on powering an MCE subrack in this configuration.
Pinout
Both connectors have the same pinout. The connector is an Amphenol 97-series, insert 22-14 (19 contacts). Use 16AWG wire, 82" long, colours as indicated.
