Realtek 8111C Platform LAN Connect Device
The Realtek 8111C component provides an interface to the back panel RJ-45
connector with integrated LEDs. This physical interface may alternately be provided
via the CNR connector.
The Realtek 8111C provides the following functions:
•
10/100/1000
Ethernet
LAN Connectivity
•
Supports RJ-45 connector with status indicator LEDs
•
Full driver compatibility
•
ACPI Power Management
•
Programmable transit threshold
•
Configuration EEPROM that contains the MAC address
RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector. The following table describes the
LED states when the board is powered up and the LAN subsystem is operating.

Universal Serial Bus (USB)
The motherboard has four USB ports and a further five can be added via internal
headers; one USB peripheral can be connected to each port. For more than nine
USB devices, an external hub can be connected to either port. The motherboard
fully supports the universal host controller interface (UHCI) and uses UHCI-
compatible software drivers.
USB features include:
•
Self-identifying peripherals that can be plugged in while the computer is
running.
•
Automatic mapping of function to driver and configuration.
•
Supports isochronous and asynchronous transfer types over the same set of
wires.
•
Supports up to
127
physical devices.
•
Guaranteed bandwidth and low latencies appropriate for telephony, audio,
and other applications.
•
Error-handling and fault-recovery mechanisms built into the protocol.
NOTE:
Computer systems that have an unshielded cable attached to a USB port
may not meet FCC Class B requirements, even if no device or a low-speed (sub-
channel) USB device is attached to the cable. Use shielded cable that meets the
requirements for high-speed (fully rated) devices.
