Service (CoS) for traffic prioritization. These features provide better understanding and control of
the network. Initial discovery of the switch on the network requires the Smart Control Center
program, a utility that runs on a PC.
The Smart Switch can be free-standing, or rack mounted in a wiring closet or equipment room. It is
IEEE-compliant and offers low latency for high-speed networking. All ports can automatically
negotiate to the highest speed. This capability makes the switch ideal for environments that have a
mix of Ethernet, Fast Ethernet, or Gigabit Ethernet devices. In addition, all RJ-45 ports operate in
half-duplex or full-duplex mode. The maximum segment length is 328 feet (100 meters) over
Category 5 Unshielded Twisted-Pair (UTP) cable, but much longer for fiber connections using
SFP GBIC modules.
Features
The following list identifies the key features of the NETGEAR Smart Switch.
• 16/24 RJ-45 10/100/1000 Mbps auto sensing Giga switching ports.

System LEDs
The following table describes the system LED designations.
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.
2 SFP Ports - 1 LED per
port SFP LINK/ACT • Solid Green - A valid 1000 Mbps SFP module link is established on the port.
•Flashing Green - Packets transmission or
reception is occurring on the port at
1000 Mbps.
•Solid Yellow - A valid 100 Mbps SFP
module link is established on the port.
•Flashing Yellow - Packets transmission or
reception is occurring on the port at
100 Mbps.
•Off - No SPD link is established on the port.

• 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.
