Network Controller
✏ NOTE
To ensure EMC product regulation compliance, the system must be used with a shielded
LAN cable.
The server board uses two Intel
®
82550PM Fast Ethernet
®
Controllers and supports two
10Base-T/100Base-TX network subsystems.
The 82550 PM 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
On the SCB2, NIC 1 can be used as both a network interface and server management interface.
NIC Connector and Status LEDs
The 82550 controller drives LEDs on the network interface connector that indicate link/
activity on the LAN and 10- or 100-Mbps operation. The green LED indicates network con-
nection when on and TX/RX activity when blinking. The yellow LED indicates 100-Mbps
operation when lit.
Network Teaming Features
✏
NOTE
Using both on-board NICs in a team does not allow the use of NIC 1 for server management
access. To support both network teaming features and server management features, a third
NIC must be added and teamed to NIC 2.
