3.5 Network Interface Controller (NIC)
The Intel
®
82574L GbE PCI-E Network Controller is a single, compact component with
integrated Gigabit Ethernet Media Access Controller (MAC) and Physical Layer (PHY) function.
This device is connected to the Intel
®
ICH10R. The Intel
®
Server Board S5500BC uses this
device along with the integrated Intel
®
ICH10R MAC and external Intel
®
82567 Gigabit Network
connector to provide two Gigabit Ethernet Ports designed for 10/100/1000 Mbps operation.
The Intel
®
82574L GbE PCI-E Network Controller correlates to the NIC2 connector on the back
edge of the board; the external Intel
®
82567 Gigabit Network correlates to the NIC1 connector
on the back edge of the board. When looking at the I/O panel, the NIC 1 should be wired to the
left-most RJ-45 connector. The Intel
®
82574L GbE Ethernet Controller and the external Intel
®
82567 Gigabit Network connector drive two LEDs located on each network interface connector.
The normal RJ45 link/activity LED at the right of the connector indicates network connection
when on and Transmit/Receive activity when blinking. These LEDs are be powered from a
Standby voltage rail. The speed LED at the left indicates 1000 Mbps operation when amber;
100 Mbps operation when green; and 10 Mbps when off.
