Power Connectors

The main power supply connection is obtained using a SSI Compliant 2x12 pin connector. In
addition, there are three additional power related connectors; one SSI compliant 2x4 pin power
connector (J4J1) providing support for additional 12V, one SSI compliant 1x5 pin connector
2
(J1G1) providing I C monitoring of the power supply, and one 1x2 pin IDE power connector
(U2E1) providing power to support IDE flash devices. The following tables define their pin-outs
