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.

Getting Started

Starting the Web-Based Switch Configuration Utility

Cisco Small Business SG200 Series 8-port Smart Switch 9

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 factory default IP address is

192.168.1.254.) The Log In page opens.

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 characters ', ", %, and ? are not supported.) The new password is

saved.

NOTE Password complexity is enabled by default and the new password must comply to

the default password complexity rule defined by the password strength. (See

Adding a User for more information.) The password strength check can be

temporarily disabled by selecting the Disable Password Strength Enforcement

option.

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 Log In page remains displayed on the screen.

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.

Getting Started

Starting the Web-Based Switch Configuration Utility

Cisco Small Business SG200 Series 8-port Smart Switch 10

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 Timeouts 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 Download/Backup Configuration/Log 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.
