Chapter 1
Starting a Web Browser Session
This chapter contains the procedures for starting, using, and quitting a web
browser management session on the AT-GS950/48 switch. This chapter

Chapter 1: Starting a Web Browser Session
Establishing a Remote Connection to the Web Browser Interface
The AT-GS950/48 switch is shipped with a pre-assigned IP address of
192.168.1.1. After your initial login, Allied Telesis suggests that you assign
a new IP address to your switch. To manually assign an IP address to the
switch, refer to “Configuration of IPv4 Address, Subnet Mask and Gateway
Address” on page 32. To configure the switch to obtain its IP configuration
from a DHCP server, refer to “DHCP Client Configuration” on page 53.
Whether you use the pre-assigned IP address or assign a new one, you
must set your local PC to the same subnet as the switch.
To start a web browser management session, perform the following
procedure:
1. Start your web browser.
2. In the URL field of the browser, enter 192.168.1.1.
This is the default IP address of the switch. See Figure 1.
Figure 1. Entering a Switch’s IP Address in the URL Field
The AT-S116 Management Software displays the login dialog box.
See Figure 2.

3. Enter the AT-S116 management login user name and password.
The default user name is “manager” and the default password is
“friend.” The login name and password are case-sensitive.

A web browser management session remains active even if you link to
other sites. You can return to the management web pages anytime as long
as you do not quit your browser session or the management session does
not time out. The default time-out is 10 minutes.

Web Browser Tools
You can use the web browser tools to move around the management
pages. Selecting Back on your browser’s toolbar returns you to the
previous display. You can also use the browser’s Bookmark feature to
save the link to the switch.

System Management Information
This section explains how to assign a name, location, and contact
information for the AT-GS950/48 switch. This information helps in
identifying each specific AT-GS950/48 switch among other switches in the
same local area network. Entering this information is optional.
Allied Telesis recommends that you assign a name to the switch.
Naming each switch can help you identify the specific switch you
want to manage among others. It can also help to avoid performing
a configuration procedure on the wrong switch.
To set a switch’s administration information, perform the following
procedure:
1. From the main menu on the left side of the page, click the System
folder.
The System folder expands.
2. From the System folder, select Management.

identifier that identifies the switch model. You cannot change this
parameter.
