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.  
Powered-Device Port  
The NETGEAR GS108T Smart Switch is a PoE Powered Device (PD) and can receive power  
from PoE Power Sourcing Equipment (PSE). To power the GS108T Smart Switch from a PoE  
power source, such as the NETGEAR GS748TPS ProSafe Gigabit Stackable PoE Smart Switch,  
you can connect the PSE to Port 1 on the GS108T Smart Switch through a standard Cat5 UTP  
cable. This allows the GS108T Smart Switch to be powered by PoE.

GS108T Hardware Installation Guide  
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).  
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 will  
be set to the factory default values. To operate the Factory Defaults button, insert a device such as  
a paper clip into the opening to press the recessed button for at least two seconds.

Characteristics Requirements  
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.  
Alternatively, you can use IEEE802.3af-compliant power sourcing equipment (PSE) to  
supply power to the switch. Connect the PSE to Port 1 on the GS108T switch.  
When both an external power supply and a PoE source are connected to the GS108T  
switch, the external power source takes priority.  
Environmental  
Temperature - Install the switch in a dry area, with ambient temperature between 0 and  
50ºC (32 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.  
Step 2: Installing the Switch  
The GS108T 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.

GS108T Hardware Installation Guide  
Step 5: Applying Power  
The GS108T Smart Switch does not have an ON/OFF switch. You can apply or remove power by:  
Connecting or disconnecting the power adapter to or from an AC power source  
Connecting or disconnecting Port 1 to or from a PoE power source.  
Note: When both an external AC power source and a PoE power source are connected to  
the GS108T switch, the external AC power source takes priority.  
Using an AC Power Source  
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 .  
Using a PoE Power Source  
The NETGEAR GS108T Smart Switch is a PoE Powered Device (PD) and can receive power  
from IEEE 802.3af-compliant PoE Power Sourcing Equipment (PSE). To power the GS108T  
Smart Switch through PoE, use the following procedures:  
1. Connect a standard Cat5 UTP cable to Port 1 (also labeled PoE-PD) on the front of the switch.  
2. Connect the other end of the Cat5 cable to the appropriate port on the PoE Power Sourcing  
Equipment (PSE).  
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 GS108T 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 Smart Control Center. For more information about managing  
the switch, see the GS108T 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

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.
