4.4 Network Interface Controller (NIC)
The SDS2 Server Board supports two 10Base-T / 100Base-TX network subsystem using the
Intel 82550-PM NIC. The 82550 components are highly integrated PCI LAN controllers in a thin
BGA 15 mm2 package. The controller’s baseline functionality is equivalent to that of the Intel
82559 with the addition of Alert on LAN* functionality.
The SDS2 Server Board supports independent disabling of either of the two NIC controllers
under BIOS setup menu.
The 82550 supports the following features:
• 32-bit PCI/Card Bus 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 and 100 Mbps operation
• Low power +3.3 V device
