2.3.8 Serial ATA Interface
The AM4011 provides up to two SATA 1.0a interfaces running at 1.5 Gbit/s. The ports are log-
ically connected to the Intel® 3100 chipset and to the AMC ports 2-3 in the Common Options
Region of the AMC Card-edge Connector.
2.3.9 Gigabit Ethernet Interfaces
The AM4011 supports up to four Gigabit Ethernet interfaces using two Intel® 82571EB Dual
Gigabit Ethernet controllers. Two Gigabit Ethernet copper ports (1000BASE-TX) are connected
to the RJ-45 front panel connectors J3 and J4 and two Gigabit Ethernet SerDes ports are rout-
ed to the AMC ports 0-1 in the Common Options Region of the AMC Card-edge Connector.
The Intel® 82571EB Dual Gigabit Ethernet controller is optimized to deliver high performance
data throughput with the lowest power consumption. The controller’s architecture includes a
large packet buffer (48 kB per port) which maintains superior performance. The Ethernet con-
trollers are directly connected to the Intel® 3100 chipset using two x4 PCI Express ports. The
Boot from LAN feature is supported.
2.3.9.1 Gigabit Ethernet Connectors
The Ethernet connectors are realized as two RJ-45 connectors, J3 (GbE D) and J4 (GbE C).
The interface provides automatic detection and switching between 10Base-T, 100Base-TX and
1000Base-T data transmission (Auto-Negotiation). Auto-wire switching for crossed cables is
also supported (Auto-MDI/X).
