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.
SFP GBIC Module
The GBIC module bays accommodate standard SFP GBIC modules, such as the AGM731F,
AGM732F, or AGM733 from NETGEAR, allowing fiber connections on the network. The module
bay is a combo port, sharing a connection with an RJ-45 port. Being a combo port, only one type
of connection can be active at any given time. For example, both copper and fiber port cannot be
used at the same time. If both connectors are plugged in at the same time, the fiber port will be
active.
The SFP GBIC bay accommodates a standard SFP GBIC module.
Factory Defaults Button
The Smart Switch has a Factory Default button so that you can remove the current configuration
and return the device to its factory settings. When you enable the Factory Default button, all
settings, including the password, VLAN settings and port configurations will be removed.

Step 7: Managing the Switch using a Web Browser or the PC
Utility
The NETGEAR Smart Switch contains software for viewing, changing, and monitoring the way it
works. This management software is not required for the switch to work. The ports can be used
without using the management software. However, the management software enables the setup of
VLAN and Trunking features, and also improves the efficiency of the switch, which results in the
improvement of its overall performance as well as the performance of the network.
After powering up the switch for the first time, the Smart Switch can be configured using a Web
browser or a utility program called SmartWizard Discovery. For more information about
managing the switch, see the GS716T/GS724T Series Software Administration Manual on the
Smart Switch Resource CD.

Auto-Negotiation
The RJ-45 ports negotiate the correct duplex mode and speed if the device at the other end of the
link supports auto negotiation. If the device does not support auto negotiation, the switch only
determines the speed correctly and the duplex mode defaults to half-duplex.
The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided
that the attached device supports auto-negotiation.
