USB Connectors
Your system contains two Universal Serial Bus (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. Figure B -7 illustrates the USB connector and
Table B -6 defines the pin assignments and interface signals for the USB connector.

Integrated Network Interface Controller Connectors
Your system has two integrated network interface controllers (NIC)—a 10/100–megabit-per-second (Mbps) NIC and a 10/100/1000-Mbps NIC.
The 10/100-Mbps NIC provides all the functions of a separate network expansion card and supports both the 10 Base-T and 100 Base-TX Ethernet standards.
The 10/100/1000-Mbps NIC provides faster 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.
Both NICs include a Wakeup On LAN feature that enables the system to be started by a special LAN signal from a server management console. Wakeup On
LAN provides remote system setup, software downloading and installation, file updates, and asset tracking after hours and on weekends when LAN traffic is
typically at a minimum.

Network Cable Requirements
Your system's RJ45 NIC connectors are designed for attaching an unshielded twisted pair (UTP) Ethernet cable equipped with standard RJ45-compatible plugs.
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.
l Use Category 5 or greater wiring and connectors.
9 VCC N/A Vcc
11 NC N/A No connection
12 DDC data out O Monitor detect data
13 HSYNC O Horizontal synchronization
14 VSYNC O Vertical synchronization
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.
