Connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to this connector.
The 100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 or
higher cabling.
The Ethernet connector has one LED that indicates Ethernet-link status. When this
LED is lit, it indicates that there is an active connection on the Ethernet port. Activity
between the computer and the network is indicated by the Ethernet transmit/receive
activity LEDs on the front and rear of the computer (see "Server controls,
connectors, and LEDs" on page 4).
