Refer to Appendix A, "Specifications, Safety, & Compliance" on page 15 for power specification details. 10/100BaseT Ethernet Ports There are eight 10/100BaseT Ethernet ports on the W-620 Series. Ports 0 through 3 support Power over Ethernet (PoE). Ports 4 through 7 do not support PoE and do not have a PoE LED. Instead, they have an LED labeled 100, which indicates interface speed. For information about LED behavior, see Table 3. 10/100/1000Base-T Gigabit Ethernet Port There is one 10/100/1000Base-T Gigabit Ethernet (RJ-45) port on the W-620 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 3 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.
