Dell PowerConnect W-620 Controller | Installation Guide About the W-620 Controller | 9Rear ViewFigure 2 W-620 Series Series Rear ViewAC Power SocketThe W-620 Series supports integrated AC powering and the AC power socket on the rear of the unit is for usewith an AC power cord (country-specific). Refer to Appendix A, “Specifications, Safety, & Compliance” onpage 15 for power specification details.10/100BaseT Ethernet PortsThere 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 PortThere is one 10/100/1000Base-T Gigabit Ethernet (RJ-45) port on the W-620 Series. 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 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.Figure 3 Gigabit Ethernet Port Pin-Out10/100/1000Base-TGigabit Ethernet Port10/100Base-TEthernet PortsUSB portMedia Eject ButtonSerial Console PortAC Power Socket1000Base-T GigabitEthernet PortRJ-45 FemalePin-OutSignal Name12345678BI_DC+BI_DC-BI_DD+BI_DD-BI_DA+BI_DA-BI_DB+BI_DB-FunctionBi-directional pair +CBi-directional pair -CBi-directional pair +DBi-directional pair -DBi-directional pair +ABi-directional pair -ABi-directional pair +BBi-directional pair -B
