Device Hardware Interfaces
RJ-45 Ports
RJ-45 ports are autosensing 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.
Reset Button
The Smart Switch has a Reset button on the front panel to allow you to manually reboot the
switch. This action is equivalent to powering the unit off and back on. The last saved
configuration is loaded into the switch as it resets. To operate the Reset button, insert a
device such as a paper clip into the opening to press the recessed button. The front-panel
LEDs should extinguish and light again as the switch performs its Power On Self Test
(POST).

Physical Description

NETGEAR GS110T Smart Switch
Factory Defaults Button
The Smart Switch has a Factory Defaults button on the front panel so that you can remove
the current configuration and return the device to its factory settings. When you enable the
Factory Defaults button, all settings including the password, VLAN settings, and port
configurations are removed. To operate the Factory Defaults button, insert a device such as a
paper clip into the opening to press the recessed button for two seconds.

Step 2: Installing the Switch
The GS110T Smart Switch can be used on a flat surface or mounted on the wall.
Installing the Switch on a Flat Surface
The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on each of
the four concave spaces on the bottom of the switch. The rubber footpads cushion the switch
against shock/vibrations.
Wall Mounting the Switch
To mount the switch on a wall (optional), install the two provided screws in positions that
correspond to the slots on the bottom side of the GS110T, then mount the switch.
Power source Provide a power adapter (included). Power specifications for the switch are shown in
Appendix A. Ensure the AC outlet is not controlled by a wall switch, which can
accidentally turn off power to the outlet and the switch.
Environmental • Temperature - Install the switch in a dry area, with ambient temperature between 0ºC
and 50ºC (32ºC and 122ºF). Keep the switch away from heat sources such as direct
sunlight, warm air exhausts, hot-air vents, and heaters.
• Operating humidity - The installation location should have a maximum relative
humidity of 90%, non-condensing.
• Ventilation - Do not restrict airflow by covering or obstructing air inlets on the sides of
the switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling. Be
sure there is adequate airflow in the room or wiring closet where the switch is installed.
• Operating conditions - Keep the switch at least 6 ft. (1.83 m) away from nearest
source of electromagnetic noise, such as a photocopy machine.

NETGEAR GS110T Smart Switch
Step 5: Applying AC Power
Before connecting the power cord, select an AC outlet that is not controlled by a wall switch,
which can turn off power to the switch. After selecting an appropriate outlet, use the following
procedure to apply AC power:
1. Connect the end of the supplied IEC AC power adapter cable to the power receptacle
on the back of the switch.
2. Connect the AC power adapter cable into a power source such as a wall socket or power
strip.
When applying power, the Power LED on the switch’s front panel illuminates.
If the Power LED does not go on, check that the power cable is plugged in correctly and that
the power source is good. If this does not resolve the problem, refer to Appendix A.
Step 6: Managing the Switch using a Web Browser or the
PC Utility
The GS110T 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 program called Smart Control Center Utility. For more information about
managing the switch, see the Gigabit Advanced Smart Switch Series Software Administration
Manual on the Smart Switch Resource CD.
Note: When the device powers up, there is a default IP
address already configured on the device. The
default IP address is 192.168.0.239 and subnet
mask 255.255.255.0.
