The board has several hardware management features, including thermal and voltage monitoring. Depending on power management settings in the operating system. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 10 lists Intel D2550DC2 Desktop Board Iflash power states supported by the board along with the associated system power targets.

See the ACPI specification for a complete description of the various system and power states. Context saved to RAM. No Intel D2550DC2 Desktop Board Iflash D3 no power except for wake-up logic. Context saved to disk. Cold boot is required.

Service can be performed safely. Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis power supply. Dependent on the standby power consumption of wake-up devices used in the system. S4 implies operating system support only.

Intel® Desktop Board D2550DC2

In addition, software, drivers, and peripherals must fully support ACPI wake events Hardware Support The board provides several power management hardware features, including: While in the S3 sleep-state, the computer will appear to be off the power supply is only supplying Standby power, Intel D2550DC2 Desktop Board Iflash the front panel LED will be amber or secondary color if dual colored, or off if single colored. When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 11 on page 34 lists the devices and events that can wake the computer from the S3 state.

The use of Instantly Available PC technology requires operating system support and drivers for any installed M. Figure 8 shows the location of the standby power LED.

CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or Intel D2550DC2 Desktop Board Iflash any devices connected to the board. Failure to do so could damage the board and any attached devices. On a system that has 32 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions.


These functions include the following: The board remaps physical memory from the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just above the 4 GB boundary. All installed system memory can be used when there is no overlap of system addresses.

Support for Intel® Desktop Board DDC2

The other internal connectors and headers are not overcurrent protected and should connect only to devices inside the computer s chassis, such as fans and internal peripherals. Do not use these connectors or headers to power devices external to the computer s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. Furthermore, improper connection of USB header single wire connectors may eventually overload the overcurrent protection and cause damage to the board. The connectors and headers can be divided into these groups: Back Panel Connectors 40 41 Technical Reference Connectors and Headers Bottom Figure 11 shows the locations of the connectors and headers on the bottom-side of the board.

The back panel DC connector is compatible with a 5. The maximum current rating is Intel D2550DC2 Desktop Board Iflash A.

The Auxiliary Power Connector is limited to 1. For information about Refer to Power supply considerations Section 2. Table 17 lists the signal names of the front panel header.
