Front and Back Panels
Figures 2-1 and 2-2 show the key components on the front and back panels of the NETGEAR GS748T Gigabit Smart Switch.
The front panel contains RJ-45 jacks with LEDs and 4 SFP GBIC module bays. The back panel has a standard AC power receptacle for
accommodating the supplied power cord.

10/100/1000 Mbps RJ-45 Ports

As Figure 2-1 shows, the GS748T Gigabit Smart Switch has 48 10/100/1000 Mbps RJ-45 ports. These ports are auto-sensing 10/100/1000 Mbps
ports: When you insert a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex
mode (half- 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 lets you attach devices to the RJ-45 ports
either straight-through or crossover cables. When you insert a cable into the switch's RJ-45 port, the switch automatically:
•
Senses whether the cable is a straight-through or crossover cable, and
•
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.
