Providing 10/100/1000 Mbps copper connectivity  
The GS510TP Smart Switch also provides the benefit of administrative management with a  
complete package of features for the observation, configuration, and control of the network.  
With a Web-based Graphical User Interface (GUI), the switch’s many capabilities can be  
viewed and used in a simple and intuitive manner. The switch’s management features  
include configuration for port and switch information, VLAN for traffic control, port trunking for  
increased bandwidth, and Class of 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 Netgear Smart Control Center program, a utility that runs on a PC.  
The GS510TP Smart Switch is a free-standing switch. It is IEEE-compliant and offers low  
latency for high-speed networking. All ports can automatically negotiate to the highest speed.

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).  
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 GS510TP Smart Switch  
Table 3. Site Requirements (continued)  
Characteristics Requirements  
Power source  
Environmental  
AC power cord (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.  
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. (1.83m) away from nearest  
source of electromagnetic noise, such as a photocopy machine.  
Step 2: Installing the Switch  
The GS510TP Smart Switch can be used on a flat surface or mount in a rack.  
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.  
Rack Mounting the Switch  
To mount the switch in a rack, attach the included rack mounting brackets to the switch. Then  
connect the switch to the rack, securing the mounting brackets to the rack.

Step 3: Checking the Installation  
Before applying power to the switch, perform the following:  
Inspect the equipment thoroughly.  
Verify that all cables are installed correctly.  
Check cable routing to make sure cables are not damaged or creating a safety hazard.  
Ensure all equipment is mounted properly and securely.  
Step 4: Connecting Devices to the Switch  
The following procedure describes how to connect PCs to the switch’s RJ-45 ports. The  
GS510TP Smart Switch contains Auto Uplink technology, which allows the attaching of  
devices using either straight-through or crossover cables.  
`

Figure 5. Connect PCs to the Switch’s RJ-45 Ports  
Connect each PC to an RJ-45 network port on the Switch front panel (Figure 5). Use  
Category 5 (Cat5) Unshielded Twisted-Pair (UTP) cable terminated with an RJ-45 connector  
to make these connections.  
Note: Ethernet specifications limit the cable length  
between the switch and the attached device to 100 m  
(328 ft.).  
Installation  
21  
 
           
NETGEAR GS510TP Smart Switch  
Note: The PoE port may be considered SELV circuits, if it  
is not likely to require connection to an Ethernet  
network with outside plant routing, including campus  
environment; and the installation instructions clearly  
state that the ITE is to be connected only to  
PoEnetworks without routing to the outside plant.  
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 AC power cord to the power receptacle on the back of  
the switch.  
2. Connect the AC power cord 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 cord 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 GS510TP 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.

Additional Troubleshooting Suggestions  
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the  
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.
