Models 5160D and 5200D System Board Power Connectors
The following information covers the CU430HX system board included in Equium Models
5160D and 5200D.
The CU430HX system board is paired with a power supply that supports remote power
on/off, so the system board can turn off the system power under software control. The
Powerman utility supplied for Windows 3.1x allows for soft-off as does the shutdown icon in
Windows 95 Start menu. The system BIOS turns the system power off when it receives the
proper APM command from the OS. For example, Windows 95 issues this APM command
after the user selects "Shutdown the computer" option. APM must be enabled in the system
BIOS and OS in order for the soft-off feature to work correctly. The user has the ability to
determine the state of the power supply, so if the system was turned on when power was
disconnected, the system turns back on when power is reapplied or it remains off, depending
on the user setup configuration in CMOS.
Table A-33 provides the pinout listing for the primary power supply connector of the CU430HX system board.
