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
The SX220 server 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 indicates
link/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.
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.
The network controller provides several options for increasing throughput and fault
tolerance when running Windows NT 4.0, Windows 2000, NetWare 4.1x or newer, or
Linux:
•
Adapter Fault Tolerance (AFT) - provides automatic redundancy for your
adapter. If the primary adapter fails, the secondary takes over. AFT works
with any hub or switch.
