Chapter Two System Features
Network Controller
The server board includes a 10BASE-T/100BASE-TX network solution based on the
Intel 82559 single chip Fast Ethernet PCI Bus Controller. As a PCI bus master, the
controller can burst data at up to 132 MBps. The controller contains two receive
and transmit FIFO buffers that prevent data overruns or underruns while waiting for
access to the PCI bus. The controller has the following:
q 32 bit PCI bus master interface (direct drive of bus), compatible with PCI
Bus Specification, Revision 2.1
q Chained memory structure with improved dynamic transmit chaining for
enhanced performance
q Programmable transmit threshold for improved bus utilization
q Early receive interrupt for concurrent processing of receive data
q Onchip counters for network management
q Autodetect and autoswitching for 10 or 100 Mbps (Megabits per second)
network speeds; capable of full or half duplex, with back-to-back transmit at
100 Mbps
The network status LEDs on the server board indicate:
q Transmit/receive activity on the LAN
q Valid link to the LAN
q 10/100 Mbps transfer mode
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible. The server may be locked
automatically if there is no keyboard or mouse activity for a predefined length of
time, if specified through the System Setup Utility (SSU). Once the inactivity
(lockout) timer has expired, the keyboard and mouse do not respond until the
previously stored password is entered.
ACPI
The L440GX+ supports the Advanced Configuration and Power Interface (ACPI) as
defined by the ACPI 1.0 and PC97 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
fan and processor fans will still run.
