Two 2-row 16-pin Ethernet headers are located on
the top side of CPC1600. They are used by two
Gigabit Ethernet interfaces.
Two 4-pin headers allow connection of Ethernet
LEDs.
All these headers require cable adapters to connect
network cables to standard RJ45 connectors.
CPC1600 is equipped with two 10Base-T/100Base-
TX/1000Base-T Ethernet ports based on Intel®
82571EB Dual Gigabit Ethernet PCI-Express bus
controller. Host interface is one 4x PCI Express
lanes.
The Intel® 82571EB Gigabit Ethernet controller architecture combines high performance and low
power consumption. The controller's features include independent transmit and receive queues to
limit PCI-Express bus traffic, and PCI-Express interface providing efficient bus utilization by
increased use of bursts.
The interfaces provide auto-detection and switching between 10Base-T, 100Base-TX, and
1000Base-T operation modes. Each of the two Ethernet channels may be disabled via the BIOS
Setup or user software utility to free up system resources.
The following table presents pinouts of these connectors.
