7.1Power 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 (J1G1) providing I2C 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
