10. On-board Connector/Header Overview
This section identifies the location and pin-out for on-board connectors and headers of the server board that
provide an interface to system options/features, on-board platform management, or other user accessible
options/features.
10.1 Power Connectors
The server board includes several power connectors that are used to provide DC power to various devices.
10.1.1 Main Power
Main server board power is supplied from two slot connectors, which allow for one or two (redundant) power
supplies to dock directly to the server board. Each connector is labeled as “MAIN PWR 1” or “MAIN PWR 2”
on the server board. The server board provides no option to support power supplies with cable harnesses.
In a redundant power supply configuration, a failed power supply module is hot-swappable. The following
tables provide the pin-out for both “MAIN PWR 1” and “MAIN PWR 2” connectors.
