Chapter 1: Getting Started
Starting a Management Session
To start a management session on the switch, perform the following
procedure:
1. In a web browser address box, enter the following IP address:
192.168.1.1
The main page for the AT-S88 management software is shown in
Figure 1.
Figure 1. Main Page
8
AT-S88 Management Software User’s Guide
Note
Because the switch initially has no login or password protection,
Allied Telesis strongly suggests that you immediately do two things:
Change the IP address, as described in “Configuring the IP Address,
Subnet Mask, and Gateway Address” on page 12.
Add an administrative user and password who can access the
switch, as described in “Adding an Administrative User” on page 15.

Chapter 2: Basic Switch Parameters
Configuring the IP Address, Subnet Mask, and Gateway Address
Warning
Be sure to record the switch’s IP address in a safe place. When you
change the switch’s IP address you lose your connection. Because
the AT-FS750/24POE Fast Ethernet Smart Switch does not have a
console port, your only means of managing the switch is through a
web browser, which requires that you have the switch’s IP address.
To configure the IP settings, perform the following procedure:
1. From the main menu, select System > IP Setup.
The IP Setup page is shown in Figure 2.
Figure 2. IP Setup Page
2. From the VLAN ID list, select the VLAN you want the switch to be a
part of.
Note
The default VLAN is 1. To create more VLANs, refer to Chapter 8,
”VLANs” on page 65.
3. In the IP Address field, enter an IP address for the switch.
4. In the Network Mask field, enter an IP address for the subnet mask.
5. In the Default Gateway field, enter the IP address of the default
gateway.
6. Click OK.
The settings are immediately implemented and you lose your
connection to the switch.
12
AT-S88 Management Software User’s Guide
7. Log into the switch using its new IP address.
8. From the main menu, select Save Configuration.
The Save Configuration page is shown in Figure 3.
Figure 3. Save Configuration Page
Note
If you do not save your changes, they are discarded when you
reboot the switch.
9. Click Save.
For information about DHCP, see “Enabling or Disabling DHCP” on
page 14.
Warning
Be sure to record the switch’s IP address in a safe place. When you
change the switch’s IP address you lose your connection. Because
the switch does not have a console port, your only means of
managing the switch is through a web browser, which requires that
you have the switch’s IP address.

Chapter 2: Basic Switch Parameters
Enabling or Disabling DHCP
To enable or disable the DHCP client, perform the following procedure:
1. From the main menu, select System > IP Setup.
The IP Setup Page is shown in Figure 2 on page 12.
2. From the DHCP Client list, choose Enabled or Disabled.
The default setting is disabled.
Note
If you lose connectivity after enabling DHCP or to determine the
switch’s new IP address in the future, use the SSM Utility. You can
access the utility in one of the following ways:
- Click the SSM Utility link on the AT-FS750/48 Fast Ethernet Switch
CD, and on the SSM Utility page, click the SSM Utility link.
- Download the SSM Utility files and documentation located in the
SSM Utility folder on the AT-FS750/48 Fast Ethernet Switch CD.
- Download the SSM Utility files and documentation from the Allied
Telesis website, www.alliedtelesis.com.

Configuring System Administration Information
You can allow multiple users to access and administer the system by
adding their passwords to the system and/or set up password protection.
Note
When you start up the switch for the first time, you should add a user
to the system, protected by a password, who will be managing the
switch.

Setting Up IP Address Access
You can restrict remote management of the switch by creating an IP
access list. The switch uses the list to filter the management packets it
receives and accepts and processes only those packets that originate
from an IP address in the list. In addition to creating the list, you can
disable or enable the IP access list filtering.
Adding an IP
Address to the IP
Access List
To add an IP address to the IP access list, perform the following
procedure:
