Overview
The HP 1920 Switch Series can be configured through the command line interface (CLI), Web interface,
and SNMP/MIB. These configuration methods are suitable for different application scenarios.
• The Web interface supports all 1920 Switch Series configurations.
• The CLI provides configuration commands to facilitate your operation. To perform other
configurations not supported by the CLI, use the Web interface.

Configuring the switch in the Web interface
Restrictions and guidelines
To ensure a successful login, verify that your operating system and Web browser meet the requirements,
and follow the guidelines in this section.
Operating system requirements
• The device supports the following operating systems:
{ Windows XP
{ Windows 2000
{ Windows Server 2003 Enterprise Edition
{ Windows Server 2003 Standard Edition
{ Windows Vista
{ Windows 7
{ Linux
{ MAC OS
• If you are using a Windows operating system, turn off the Windows firewall. The Windows firewall
limits the number of TCP connections. When the limit is reached, you cannot log in to the Web
interface.
Web browser requirements
• HP recommends that you use the following Web browsers:
{ Internet Explorer 6 SP2 or higher
{ Mozilla Firefox 3 or higher
{ Google Chrome 2.0.174.0 or higher
• If you are using a Microsoft Internet Explorer browser, you must enable the security settings (see
"Enabling securing settings in a Mic
rosoft Internet Explorer browser"), including Run ActiveX
controls and plug-ins, Script ActiveX controls marked safe for scripting, and Active scripting.
• If you are using a Mozilla Firefox browser, you must enable JavaScript (see "Enabling JavaScript in a
Fi
refox browserEnabling JavaScript in a Firefox browser")
.
Enabling securing settings in a Microsoft Internet Explorer browser
1. Launch the Internet Explorer, and select Tools > Internet Options from the main menu.
2. Select the Security tab, and select the content zone where the target Website resides, as shown
in Figure 1.
3
Figure 1 Internet Explorer settings (1)
3. Click Custom Level.
4. In the Security Settings dialog box, enable Run ActiveX controls and plug-ins, Script ActiveX
controls marked safe for scripting, and Active scripting.

Figure 2 Internet Explorer settings (2)
5. Click OK to save your settings.
Enabling JavaScript in a Firefox browser
1. Launch the Firefox browser, and select Tools > Options.
2. In the Options dialog box, click the Content icon, and select Enable JavaScript.
5
Figure 3 Firefox browser settings
3. Click OK to save your settings.
Others
• The Web interface does not support the Back, Next, and Refresh buttons provided by the browser.
Using these buttons might result in abnormal display of Web pages.
• To ensure correct display of Web page contents after software upgrade or downgrade, clear data
cached by the browser before you log in.
• If you click the verification code displayed on the Web login page, you can get a new verification
code.
• Up to five users can concurrently log in to the device through the Web interface.
• A list can contain a maximum of 20000 entries if displayed in pages.
• The PC where you configure the device is not necessarily a Web-based network management
terminal. A Web-based network management terminal is a PC used to log in to the Web interface
and is required to be reachable to the device.
• After logging in to the Web interface, you can select Device > Users from the navigation tree, create
a new user, and select Wizard or Network > VLAN interface to configure the IP address of the
VLAN interface acting as the management interface. For more information, see the corresponding
configuration guides of these modules.

Overview
The device provides web-based configuration interfaces for visual device management and
maintenance.
Figure 4 Web-based network management operating environment
Logging in to the Web interface
You can use the following default settings to log in to the web interface through HTTP:
• Username—admin
• Password—None
• IP address of VLAN-interface 1 on the device—IP address of the device, depending on the status of
the network where the device resides.
{ If the device is not connected to the network, or no DHCP server exists in the subnet where the
device resides, you can get the IP address of the device on the label on the device. IP address
is 169.254.xxx.xxx. If the MAC address is 08004E000102, the IP address would be
169. 254 .1. 2.
{ If a DHCP server exists in the subnet where the device resides, the device will dynamically
obtain its IP address through the DHCP server.
You can log in to the device through the console port, and execute the summary command to view the
information about its IP address.
<Sysname> summary
Select menu option: Summary
IP Method: DHCP
IP address: 169.254.1.2
Subnet mask: 255.255.0.0
Default gateway: 0.0.0.0
<Omitted>
Assuming that the IP address of the device is 169.254.1.2, to log in to the Web interface of the device
from a PC:
1. Connect the Ethernet interface of the device to a PC by using a crossover Ethernet cable. By default,
all interfaces belong to VLAN 1.
2. Configure an IP address for the PC and make sure that the PC and device can reach each other.
For example, assign the PC an IP address (for example, 169.254.1.27) within 169.254.0.0/16
(except for the IP address of the device).
3. Open the browser, and input the login information.
a. Type the IP address http:// 169.254.1.2 in the address bar and press Enter.
The login page of the web interface (see Figure 5) appears.

b. Enter the username admin and the verification code, leave the password blank, and click
Login.

Logging out of the Web interface
CAUTION:
• You cannot log out by directly closing the browser.
• For security purposes, log out of the Web interface after you finish your operations.
1. Save the current configuration.
Because the system does not save the current configuration automatically, HP recommends that
you perform this step to avoid loss of configuration.
2. Click Logout in the upper-right corner of the Web interface.
Web interface
The Web interface includes three parts: navigation tree, title area, and body area, as shown in Figure 6.
