Configure the switch

Plus Gigabit Ethernet Switches are plug-and-play, so they can be used without any

configuration. Just connect power, connect to your network and to your other devices,

and you’re done.

For easiest access, we recommend that you cable the switch to a network with a router

or DHCP server that assigns IP addresses and power on the switch. However, it is also

possible to configure the switch connected directly only to the computer that you are

using to configure it, and not connected to the network (off-network).

You can configure and manage advanced features of the switch by using your computer’s

web browser and accessing the switch at its IP address.

If you use a Mac or a 64-bit Windows-based computer, you can use the NETGEAR Switch

Discovery Tool to discover the switch in your network and access the local browser–based

management interface of the switch.

If your Mac supports Bonjour, you can use Bonjour to discover the switch in your network

and access the local browser interface of the switch.

For more information, see the following sections:

•Access the switch using a web browser on page 7

•Use the NETGEAR Switch Discovery Tool to access the switch on page 9

•Access the switch from a Mac using Bonjour on page 11

Access the switch using a web browser

This manual describes how to use the local browser–based management interface,

referred to as the device UI.

You can access and configure the switch directly through its device UI by entering the

IP address of the switch in the address bar of a browser. When you access the device

UI to configure the switch, it's simpler if the switch is not connected to your network

(off-network). You can also configure the switch with it connected to your network,

router, or modem, (on-network) but you must be able to determine the IP address of

the switch if your network uses DHCP.

Access a switch that is connected to a network

By default, the DHCP client of the switch is enabled. To access the switch, use the IP

address that the DHCP server assigned to the switch.

To determine the IP address of the switch, do one of the following:

•If you use a Mac or a 64-bit Windows-based computer, use the NETGEAR Switch

Discovery Tool to detect the IP address (see Use the NETGEAR Switch Discovery

Tool to access the switch on page 9).

•If you use a Mac that supports Bonjour, use Bonjour to detect the IP address (see

Access the switch from a Mac using Bonjour on page 11).

•Access the DHCP server.

•Use an IP scanner utility.

To use your web browser to configure a switch that is connected to a network:

1. Cable the switch to a network with a router or DHCP server that manages IP

addresses.

2. Power on the switch.

The DHCP server assigns the switch an IP address.

3. Connect your computer to the same network as the switch.

4. Determine the IP address of the switch.

By default, the DHCP client of the switch is enabled. Use the IP address that the

DHCP server assigned to the switch.

5. Open a web browser, and enter the IP address of the switch.

The login page displays.

6. Enter the device admin password.

Use the default password printed on the device label the first time you log in, and

then you must set a new device password. The password is case-sensitive.

7. Click the Login button.

You can now configure additional options for the switch through the device UI.

For information about setting up a fixed (static) IP address for the switch, see Specify

IP address settings for the switch on page 46.

Access a switch that is off-network

To use your web browser to configure a switch that is not connected to a network:

1. Record your computer’s TCP/IP configuration settings, and then configure the

computer with a static IP address of 192.168.0.210 and 255.255.255.0 as the subnet

mask.

Note: If you are unsure how to do this, visit the support website at

netgear.com/support and search for Static IP address on computer.

2. Plug the switch into a power outlet and then connect your computer to the switch

using an Ethernet cable.

You can connect the Ethernet cable to any port on the switch.

3. Open a web browser, and enter http://192.168.0.239.

This is the default address of the switch.

The login page displays.

4. Enter the switch password.

The default password is password. The password is case-sensitive.

5. Click the Login button.

You can now configure additional options for the switch through the device UI.

For information about setting up a fixed (static) IP address for the switch, see Specify

IP address settings for the switch on page 46.

6. After you complete the configuration of the switch, reconfigure the computer that

you used for this process to its original TCP/IP settings.

You can now connect your switch to your network using an Ethernet cable.

Use the NETGEAR Switch Discovery Tool to

access the switch

For easiest access, we recommend that you cable the switch to a network with a router

or DHCP server that assigns IP addresses, power on the switch, and then use a computer

that is connected to the same network as the switch.

Depending on your model switch, the NETGEAR Switch Discovery Tool lets you discover

the switch in your network and access the device UI of the switch from a Mac or a

Windows-based computer.
