Reset Button

The Reset button of the GS108T triggers a hardware reset of the switch. Figure 2-3 shows its location on the front panel. This action is equivalent to switching the unit power 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).

Desktop Switching

Your NETGEAR GS108T Gigabit Smart Switch can be used as a desktop switch in a small network that gives users 1000 Mbps access to a file server. With full-duplex mode enabled, the switch port connected to the server or PC can provide 2000 Mbps throughput.

Checking the Installation

Before you apply power, inspect the equipment thoroughly to:

Verify that all cables are installed correctly.
Check that cables are not damaged and that cable routing does not interfere with equipment to create a safety hazard.
Ensure that all equipment is mounted properly and securely.

Connecting Devices to the Switch

The following procedure describes how to connect devices to the switch’s RJ-45 ports. Your NETGEAR GS108T Gigabit Smart Switch contains Auto Uplink technology, which enables you to attach devices using either straight-through or crossover cables.

Applying Power

Because the NETGEAR GS108T Gigabit Smart Switch has no ON/OFF switch, AC power must be controlled by means of the power adapter. Select an appropriate unswitched, grounded AC facility outlet to avoid any future inadvertent power interruptions. Use the following procedure to apply AC power:

Connect the female end of the supplied IEC AC power adapter cable to the power receptacle on the back of the switch.
Connect the AC power adapter cable to the DC jack.

When you apply power, the green Power LED on the switch front panel illuminates.

Switching Management Through a Web Browser or Utility Program (Initial Configuration)

Your NETGEAR GS108T Gigabit Smart Switch has embedded management software for viewing, changing, and monitoring its activity and configuration. You need not use this management software for it to function as a simple switch. However, the management software enables you to set up advanced features such as VLANs and Trunking and also enables you to configure the switch for improved efficiency and performance. As a result, you can improve the overall performance of your network.
After you power-up the switch for the first time, you can configure it using a Web browser or a utility program called Smartwizard Discovery. For more information about managing the switch, see the User Manual on the Smart Switch Resource CD.

Additional Troubleshooting Suggestions

If the suggestions in Table A-1 do not resolve your problem, refer to the troubleshooting suggestions in this section.

Network Adapter Cards
Ensure that the network adapter cards installed in the PCs are in working condition and their most recent software drivers have been installed.

Configuration
If problems occur after altering the network configuration, restore the original connections and attempt to isolate the problem by implementing the most-recent changes, one step at a time. Make sure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet specification limitations.

Switch Integrity
If required, verify the integrity of the switch by resetting it. To do this, use the Reset button (see Chapter 2, “Physical Description”) or remove AC power from the switch and then reapply it. If the problem persists, 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.
