To purchase compatible SFP modules, contact your Dell sales representative for details and assistance. Note: Dell tests and supports Dell optics within their controller system. Third party optics are not tested or supported; therefore, Dell does not guarantee proper functionality of third party optics when used in a Dell system. 10/100/1000Base-T Gigabit Ethernet Ports There are six 10/100/1000Base-T Gigabit Ethernet (RJ-45) ports on the W-650 Series. Gigabit Ethernet uses all eight wires and each pair is used in a bi-directional fashion, meaning the same pairs are used for both data transmission and reception. Figure 2 illustrates the CAT-5 pin-out found on an RJ-45 connector. The CAT-5 pinout pairs the following pins on a 10/100/1000Base-T Gigabit Ethernet port: 1/2, 3/6, 4/5, and 7/8.
