Gigabit Ethernet uses alleight wires and each pair is used in a bi-directional fashion, meaning the same pairs are used for both datatransmission and reception. Figure 2 illustrates the CAT-5 pin-out found on an RJ-45 connector. The CAT-5 pin-out pairs the following pins on a 10/100/1000Base-T Gigabit Ethernet port: 1/2, 3/6, 4/5, and 7/8.Figure 2 Gigabit Ethernet Port Pin-OutSerial Console PortA serial console port is provided for connection to a terminal, allowing for direct local management.10/100/1000Base-T GigabitEthernet Ports with PoE1000Base-X (SFP) PortsUSB ports10/100/1000Base-TGigabit Ethernet PortsMedia Eject ButtonSerial Console PortWLAN LEDNote: Dell tests and supports Dell optics within their controller system.
