2-20 General Description

Network Controller

NOTE: To ensure EMC product regulation compliance, the system
must be used with a shielded LAN cable.
The mother board uses a dual-channel Ethernet Controller and supports 10Base-T/100Base-
TX/1000Base-T network subsystems.
The network controller supports the following features:
64-bit, 100 MHz PCI-X interface
Integrated IEEE 802.3 10Base-T, 100Base-TX, and 1000Base-T compatible PHY
IEEE 820.3u auto-negotiation support
Chained memory structure similar to the 82559, 82558, 82557 and 82596
Full duplex support at both 10 Mbps, 100 Mbps, and 1000 Mbps operation
Low power +3.3 V device
On the system board, NIC 1 can be used as both a network interface and server management
interface.

Keyboard and Mouse

The keyboard/mouse controller is PS/2-compatible. A Y-cable can be used if both a PS/2 mouse and
keyboard are required at the same time.

ACPI

The mother board 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: Normal running state.
s1: Processor sleep state. No context will be lost in this state and the processor caches will
maintain coherency.
s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing
the power button or other wakeup event will restore the system state from the disk and
resume normal operation. This assumes that no hardware changes have been made to the
system while it was off.
s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No
context is saved by the OS or hardware.
IMPORTANT: The system is off only when the AC power cord is
disconnected.
