Intel SPSH4 Server Platform Product Guide
Network Interface Controllers
NOTE
To ensure EMC product regulation compliance, the system must be used
with shielded LAN cables.
The baseboard includes two network interface controllers (NICs):
•
Intel 82550 NIC that supports 10Base-T and 100Base-TX networks
•
Intel 82544 NIC that supports 10Base-T, 100Base-TX networks, and 1000BASE-T networks
The 82550 controller supports the following features:
•
32-bit PCI, CardBus master interface
•
Integrated IEEE 802.3 10Base-T and 100Base-TX 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 and 100 Mbps operation
•
Low power +3.3 V device
•
IP checksum off-loading
NIC 1 can be used as both a network interface and server management interface.
The 82544 controller supports the following features:
•
Direct 32/64-bit, 33/66-MHz interface to the PCI bus
•
Integrated IEEE 802.3 1000BASE-T, 100BASE-TX, and 10BASE-T
•
Integrated third-generation MAC and proven IEEE 803.3ab compatible PHY
•
Full duplex support for 10-Mbps, 100-Mbps, and 1000 Mpbs operation
•
Descriptor ring management architecture optimized to deliver both high performance and
PCI/PCI-X bus efficiency
•
Low power +3.3 V device
•
IP and TCP/UDP checksum off-loading
NIC Connector and Status LEDs
The NICs drive LEDs on the network interface connectors that indicate link connection and activity
on the LAN and 10- or 100-Mbps operation.
The green LED indicates network connection when
on and TX/RX activity when blinking.
The yellow LED indicates 100-Mbps operation when lit.
