10/100/1000 Mbps RJ-45 Ports

The 8 10/100/1000 Mbps, auto-sensing RJ-45 ports of the GS108T Gigabit Smart Switch are seen
in Figure 2-1. When you insert a cable into one of these ports, the switch automatically determines
the maximum speed (10 or 100 or 1000 Mbps) and the mode (half- or full-duplex) of the attached
device. All ports support only unshielded twisted-pair (UTP) cable with an 8-pin RJ-45 plug
connection.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This
technology enables you to attach devices to the RJ-45 ports using either straight-through or
crossover cables. When you insert a cable into one of these ports, the switch automatically:
• Detects whether the combination of attached device and network cable (normal or crossover)
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 user
intervention.
LED Descriptions
The front panel of the NETGEAR GS108T Gigabit Smart Switch comprises LEDs that provide a
concise display of link, port speed, and activity. The following table summarizes the function of
these LEDs.
