Hardware

Power Input

The XTX 820 generates its own voltages on the board and only requires an external +5 volts through the four connectors (X1, X2, X3, X4) on the custom baseboard. All the XTX 820 module voltages are derived from the externally supplied +5 volts DC +/- 5%. The onboard voltages provide the CPU core voltages as well as other voltages used on the module.

Table 3-30 gives the pin outs and signals for typical ATX Power supply connector.

Notes: The shaded area denotes power or ground. The +12V and +3.3V on a typical ATX power input connector are used for the PCI bus and LCD panels, and are supplied from the external ATX power supply. The -5V and –12V are also supplied from the external ATX power supply.

NOTE

If you use a non-ATX type power supply (AT or lab power

 

supply) to power up the XTX baseboard, you must set the jumper

 

on the Ampro XTX Baseboard for a non-ATX power supply use.

Power and Sleep States

The following information only applies if an ATX power supply is connected to the XTX 820 and its respective XTX baseboard. If a non-ATX power supply is used, then the XTX 820 is only controlled by the Power-On/Off switch on the power supply and the various sleep states are not available. The ACPI sleep states are OS dependent and not available if your OS does not support power management based on the ACPI standard. The signals used for control of the ATX power supply and sleep states in general are located in Table 3-30 and described in more detail under topics Power Control Signals and Power Management Signals earlier in this chapter.

Power-On Switch

The Power-On switch on or connected to the XTX Baseboard, turns the XTX 820 and the attached power supply to a fully On condition, if you are using an ATX power supply. If the operating system (OS) supports sleep states, the OS will turn off the XTX 820 and its power supply during the OS shut down process. Typically, the Power-On switch will also transition the XTX 820 and the power supply between a fully powered on state and the various sleep states, including a fully powered off state. If the OS does not support sleep states, then the Power-On switch only turns power, On or Off, to the XTX 820 and the baseboard.
