USB Connectors
Your system contains two USB connectors for attaching USB-compliant devices. USB devices are typically peripherals such as mice, printers, keyboards, and
system speakers.
If you reconfigure your hardware, you may need pin number and signal information for the USB connectors.

Integrated Network Interface Controller Connector
Your system has an integrated 10/100/1000-megabit-per-second (Mbps) network interface controller (NIC). The NIC provides all the functions of a separate
network expansion card while providing fast communication between servers and workstations and efficient utilization of host resources, freeing more of the
system resources for other applications. It supports 10 Base-T, 100 Base-TX, and 1000 Base-T Ethernet standards.

Network Cable Requirements
Your system's RJ45 NIC connector is designed for attaching an unshielded twisted pair (UTP) Ethernet cable equipped with a standard RJ45-compatible plug.
Press one end of the UTP cable into the NIC connector until the plug snaps securely into place. Connect the other end of the cable to an RJ45 jack wall plate or
to an RJ45 port on a UTP concentrator or hub, depending on your network configuration. Observe the following cabling restrictions for 10 Base-T, 100 Base-TX,
and 1000 Base-T networks.

NOTICE:
Do not attach a USB device or a combination of USB devices that draw a maximum current over 500 milliamperes (mA) per channel or +5 volts
(V). Attaching devices that exceed this threshold may cause the USB ports to shut down. See the documentation that accompanied the USB devices for
their maximum current ratings.
