with integrated Gigabit Ethernet Media Access Controller (MAC) and Physical Layer
(PHY) function.
This device is connected to the Intel® ICH10R. The Intel® Server Board S5500BC
uses this device along with the integrated Intel® ICH10R MAC and external Intel®
82567 Gigabit Network connector to provide two Gigabit Ethernet Ports designed for
10/100/1000 Mbps operation.
The Intel® 82574L GbE PCI-E Network Controller is correlated to NIC2 connector on
the back edge of the board, the external Intel® 82567 Gigabit Network is correlated to
NIC1 connector on the back edge of the board.

ACPI
The motherboard supports the Advanced Configuration and Power Interface (ACPI) as
defined by the ACPI 2.0 specifications. An ACPI aware operating system can put the
system into a state where the hard drives spin down, the system fans stop, and all
processing is halted. However, the power supply will still be on and the processors will
still be dissipating some power, so the power supply fans will still run.
The system board supports sleep states s0, s1, s4, and s5:
■ s0: Working state.
■ s1: Processor sleep state. No context will be lost in this state and the processor
caches will maintain coherency.
■ s4: Hibernate state. Your working environment is Saved To Disk
■ s5: Shutdown.
Keyboard and Mouse
The keyboard/mouse controller is USB-compatible.
