Hardware Monitoring Components
The hardware monitor component provides low-cost instrumentation capabilities. The
features of the component include:
•
internal ambient temperature sensing
•
remote thermal diode sensing for direct monitoring of processor temperature
•
power supply monitoring (+12, +5, +3.3, +2.5, V
below acceptable values
•
I2C interface with IPMB connector
LAN Subsystem
The Intel® 82559 Fast Ethernet PCI LAN subsystem provides both 10Base-T and
100Base-TX connectivity. Features Include:
•
32-bit, 33 MHz direct bus mastering on the PCI bus
•
10Base-T and 100Base-TX capability using a single RJ-45 connector with
connection and activity status LEDs
•
IEEE 802.3u Auto-Negotiation for the fastest available connection
•
Jumperless configuration; the LAN subsystem is completely software-configurable
Intel® 82559 PCI LAN Controller
The Intel® 82559 PCI LAN controller's features include:
•
CSMA/CD Protocol Engine
•
PCI bus interface
•
DMA engine for movement of commands, status, and network data across the PCI
bus
•
Integrated physical layer interface, including:
•
complete functionality necessary for the 10Base-T and 100Base-TX network
interfaces; when in 10 Mbit/sec mode, the interface drives the cable directly
•
a complete set of Media Independent Interface (MII) management registers for
control and status reporting
•
IEEE 802.3u Auto-Negotiation for automatically establishing the best operating
mode when connected to other 10Base-T or 100Base-TX devices, whether half-
or full-duplex capable
•
Integrated power management features, including support for wake on network
event (from ACPI S3 state using the PCI bus PME# signal)
LAN Subsystem Software
