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).

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.

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.

troubleshooting suggestions in this section.
Network Adapter Cards
Ensure the network adapter cards installed in the PCs are in working condition and the
software driver has been installed.
Configuration
If problems occur after altering the network configuration, restore the original connections
and determine the problem by implementing the new changes, one step at a time. Ensure
that cable distances, repeater limits, and other physical aspects of the installation do not
exceed the Ethernet limitations.
Switch Integrity
If required, verify the integrity of the switch by resetting the switch. To reset the switch,
remove the AC power from the switch and then reapply AC power. If the problem continues,
contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are
outside of North America, please refer to the support information card included with your
product.
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.
