Device Hardware Interfaces

RJ-45 Ports

RJ-45 ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode (half- duplex or full-duplex) of the attached device. All ports support only unshielded twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug.

To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables. When inserting a cable into the switch’s RJ-45 port, the switch automatically:

Senses whether the cable is a straight-through or crossover cable.

Determines whether the link to the attached device requires a “normal” connection (such as when connecting the port to a PC) or an “uplink” connection (such as when connecting the port to a router, switch, or hub).

Configures the RJ-45 port to enable communications with the attached device, without requiring user intervention. In this way, the Auto Uplink technology compensates for setting uplink connections, while eliminating concern about whether to use crossover or straight- through cables when attaching devices.

Powered-Device Port

The NETGEAR GS108T Smart Switch is a PoE Powered Device (PD) and can receive power from PoE Power Sourcing Equipment (PSE). To power the GS108T Smart Switch from a PoE power source, such as the NETGEAR GS748TPS ProSafe Gigabit Stackable PoE Smart Switch, you can connect the PSE to Port 1 on the GS108T Smart Switch through a standard Cat5 UTP cable. This allows the GS108T Smart Switch to be powered by PoE.
