Cisco Small Business SG200 Series 8-port Smart Switches Administration Guide 8
Getting Started
This chapter provides an introduction to the web-based switch configuration
utility, and includes the following topics:
•Starting the Web-Based Switch Configuration Utility
•Quick Start Device Configuration
•Window Navigation
Starting the Web-Based Switch Configuration Utility
This section describes how to navigate the web-based switch configuration utility.
Browsers have the following restrictions:
•If you are using Internet Explorer 8, open a browser window and configure
the following settings:
Click To ols > Internet Options and then select the Security tab. Select
Local Intranet and click Sites. Click Advanced and then click Add. Add the
intranet address of the switch (http://<ip-address>) to the local intranet
zone. The IP address can also be specified as the subnet IP address, so that
all addresses in the subnet are added to the local intranet zone.
•If you are using Internet Explorer 6, you cannot directly use an IPv6 address
to access the switch. You can, however, use the Domain Name System
(DNS) server to create a domain name that contains the IPv6 address, and
then use that domain name in the address bar in place of the IPv6 address.
•If you have multiple IPv6 interfaces on your management station, use the
IPv6 global address instead of IPv6 link local address to access the switch
from your browser.
•Screen resolutions at 800x600 or lower in Internet Explorer browsers and
Firefox 3.6 are not supported by the web-based switch configuration utility.

Launching the Utility
To open the web-based switch configuration utility:
STEP 1 Open a web browser.
STEP 2 Enter the IP address of the switch that you are configuring in the address bar on
the browser, and then press Enter. The Login page opens.
NOTE When logging in by using HTTP or HTML, if you are provided an option to choose
from more than one network port, select the lowest number port.
Logging In
To log in to the web-based switch configuration utility:
STEP 1 Enter the username and password. The factory default user name is cisco and the
default password is cisco.
Note: When the switch boots with the factory default configuration, the web-
based switch configuration utility appears in the default language. After you log in,
you can download additional languages by using the Upgrade/Backup Firmware/
Language page.
STEP 2 If this is the first time that you logged on with the default user name (cisco) and the
default password (cisco) or your password has expired, the Change Admin
Password page opens. Enter the new password, confirm it, click Apply, and then
click Close. The new password is saved. (The characters ', ", %, and ? are not
supported.)
STEP 3 Click Login.
When the login attempt is successful, the Getting Started page opens.
If you entered an incorrect user name or password, an error message is displayed
and the Login page remains displayed on the screen.
Select Don’t show this page on startup to prevent the Getting Started page from
being displayed each time that you logon to the system. If you select this option,
the System Summary page is opened instead of the Getting Started page.

Logging Out
By default, the application automatically logs you out after 10 minutes of inactivity.
See Configuring the Idle Session Timeout for instructions on changing the
default timeout period.
To log out at any time, click Logout in the top right corner of any page.
!
CAUTION Unless the Running Configuration is copied to the Startup Configuration file type,
all changes made since the last time the file type was saved are lost if the switch is
rebooted. We recommend that you save the Running Configuration to the Startup
Configuration file type before logging off to preserve any changes you made
during this session.
A red Xicon displayed to the left of the Save button indicates that Running
Configuration changes have been made that have not yet been saved to the Startup
Configuration file type.
When you click Save, the page displays (see Downloading and Backing Up the
Configuration and Log Files). Save the Running Configuration by copying it to the
Startup Configuration file type. After this save, the red Xicon and the Save button
no longer display.
Quick Start Device Configuration
To simplify device configuration through quick navigation, the Getting Started
page provides links to the most commonly-used pages.
