AC Power Socket
The W-620 Series supports integrated AC powering and the AC power socket on the rear of the unit is for use
with an AC power cord (country-specific). 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 pin-
out pairs the following pins on a 10/100/1000Base-T Gigabit Ethernet port: 1/2, 3/6, 4/5, and 7/8.
