Establishing a Remote Connection to the Web Browser Interface
The AT-GS950/16 switch is shipped with a pre-assigned IP address of
192.168.1.1.
After your initial login, you may want to assign a new IP address to your
switch. To manually assign an IP address to the switch, refer to
“Configuring an IP Address, Subnet Mask and Gateway Address” on
page 10. To configure the switch to obtain its IP configuration from a
DHCP server, refer to “Enabling and Disabling the DHCP Client” on
page 14.
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, do the following procedure:
1. Start your web browser.
2. In the URL field of the browser, enter 192.168.1.1 which is the default
IP address of the switch. See Figure 1.

Configuration of IP Address, Subnet Mask and Gateway Address
This procedure explains how to change the IP address, subnet mask, and
gateway address of the switch. Before performing the procedure, note the
following:
A gateway address is only required if you want to remotely manage
the device from a management station that is separated from the
switch by a router.
To configure the switch to automatically obtain its IP configuration
from a DHCP server on your network, go to “DHCP Client
Configuration” on page 18.
To change the switch’s IP configuration, 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 IP Setup.
The IP Setup Page is displayed. See Figure 5.
Figure 5. IP Setup Page
3. Change the IP configuration parameters by observing or entering new
information in the following fields:
System MAC Address - This parameter displays the MAC
address of the switch. You cannot change this parameter.
System IP Address - Displays the current IP address of the
switch. To change the IP address, enter a new IP address.
When DHCP is enabled, you cannot change this parameter.
System Subnet Mask - Displays the current subnet mask of the
switch. To change the subnet mask, enter a new subnet mask.
When DHCP is enabled, you cannot change this parameter.

Note
Changing the IP address ends your management session. To
resume managing the device, enter the new IP address of the switch
in the web browser’s URL field, as shown in Figure 1 on page 4.
5. After you log on to the switch with the new IP address, select Save
Configuration to Flash from the main menu on the left side of the
page to save the new IP address to memory.

DHCP and ATI Web Discovery Tool
The AT-GS950/16 Gigabit Ethernet Smart switch is managed through a
web browser interface only. The factory default IP address is 192.168.1.1.
The switch does not have a local console connector, which means that
you cannot learn what the switch’s management IP address is on a web
browser without first knowing what the address is. Once the IP address is
known, you can enter it in the browser.
When the DHCP feature is enabled, a DHCP server automatically assigns
an IP address which is not advertised over the network. As a
consequence, you do not know what IP address has been assigned to the
switch.
Note
The new IP address assignment from the DHCP server may take
one to two minutes before the process is completed.
Fortunately, there is an ATI Web Discovery Tool available that resolves
this issue. It detects the MAC address, IP address and other information of
the AT-GS950 series switches that are present on your local area network.
Note
The ATI Web Discovery Tool is available for download on the
AT-GS950/16 product page at alliedtelesis.com.

DHCP Client Configuration
This procedure explains how to activate and deactivate the DHCP client
on the AT-GS950/16 switch. When the client is activated, the switch
obtains its IP configuration including an IP address and subnet mask from
a DHCP server on your network. Before performing the procedure, note
the following:
By default, the DHCP client is disabled on the switch.
The DHCP client supports DHCP Auto Configuration Settings or
BOOTP. See “DHCP Auto Configuration” on page 20 for more
information.
After you enable DHCP, your current management session ends
because a different IP address is assigned to the switch by the
DHCP server. The new IP address can be discovered using the
ATI Discovery Tool. See “DHCP and ATI Web Discovery Tool” on
page 17 for more information.
To activate or deactivate the DHCP client on the switch, 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 IP Setup.
The IP Setup Page is shown in Figure 5 on page 9.
3. From the pull-down menu next to the DHCP Mode field, select Enable
or Disable.
4. Click Apply.
When the DHCP client is Enabled, the web server connection to the
switch is lost because a different IP address is assigned to the switch
by the DHCP server.
Caution
Enabling DHCP may end your current management session.
5. Use the ATI Web Discovery Tool to find the new IP address assigned
to the switch by the DHCP server. See “DHCP and ATI Web Discovery
Tool” on page 17 for more information.

How to Start an AT-GS950/16 WEB Management Session
19
Note
The ATI Web Discovery Tool is available for download on the
AT-GS950/16 product page at alliedtelesis.com.
6. Follow the procedure to log on with the new IP address provided by the
DHCP Server as described in “Establishing a Remote Connection to
the Web Browser Interface” on page 4.
7. Save your new settings or any changes to the configuration file by
selecting Save Configuration to Flash from the main menu on the left
side of the page.
If you do not save the new configuration when DHCP is enabled, the
software reverts to the previously saved IP address value when the
switch is power cycled or rebooted. If no IP address has been
previously saved, the IP address value reverts to 192.168.1.1.
If you enable DHCP and then save your configuration, you are saving
the DHCP setting (Enabled). The next time the switch boots up, it will
use the DHCP process to establish the IP address used to manage the
AT-GS950/16 switch.
If you enter a new IP address after disabling DHCP and save your
configuration, the DHCP setting (Disabled) and the new IP address on
the switch is saved. The next time the switch boots up, it will respond
to the IP address that you entered when you re-establish contact with
the AT-S108 Management software.

DHCP Auto Configuration
If you need to automatically update the switch’s configuration files via a
remote server, the DHCP Auto Configuration feature is available for this
purpose via the DHCP server.
Note
You must enable the DHCP client so that this feature can operate
with the DHCP server. See “DHCP Client Configuration” on page 18
for more information.
To configure this feature on the switch, 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 System.
The DHCP Auto Configuration Settings Page is shown in Figure 8.
Figure 8. DHCP Auto Configuration Settings Page
3. From the Auto Configuration State field, select one of the following
choices from the pull-down menu:
Enable - The DHCP Auto Configuration feature is active.
Note
You must enable the DHCP client so that this feature can operate
with the DHCP server. See “DHCP Client Configuration” on page 18
for more information.
Disable - The DHCP Auto Configuration feature is inactive.
4. Click Apply.
The DHCP Auto Configuration setting that you have selected is now
active.
5. From the main menu on the left side of the page, select Save
Configuration to Flash to permanently save your changes.
