There are six 10/100/1000Base-T Gigabit Ethernet (RJ-45) ports on the Aruba 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 pin-out pairs the following pins on a 10/100/
1000Base-T Gigabit Ethernet port: 1/2, 3/6, 4/5, and 7/8.
