Web Configurator
In Cloud mode, the settings you configure in the Web Configurator will apply to the Switch but will not appear in the Nebula settings. The settings you configure in Nebula will overwrite the Web Configurator settings. It is the latest settings that will apply to the Switch.To avoid inconsistency, we recommend you use Nebula to configure the Switch and only use the Web Configurator for troubleshooting.System Login
1 Start your web browser.
2 The Switch is a DHCP client by default. Type “https://DHCP-assigned IP” in the Location or Address field. Press [ENTER].
You can always use the domain name “setup.zyxel” to access the Web Configurator whether the Switch is using a DHCP-assigned IP or static IP address. This requires your computer to be directly connected to the Switch. Make sure your computer can connect to a DNS server through the Switch.If the Switch is not connected to a DHCP server, type “https://” and the static IP address of the Switch (for example, the default management IP address is 192.168.1.1 through an in-band port) in the Location or Address field. Press [ENTER]. Your computer must be in the same subnet in order to access this website address.
Also, you can use the ZON Utility to check your Switch’s IP address.
3 If a “Your connection is not private” screen appears, click Advanced and Proceed to DHCP-assigned IP (unsafe) to go to the Login screen. This screen appears as the Zyxel Device uses a certificate for the HTTPS connection. See Certificates for information on using an HTTPS certificate verified by a third party to create secure HTTPS connections between your computer and the Switch.
If you see this warning page, it indicates that your browser has failed to verify the Secure Sockets Layer (SSL) certificate, which opens an encrypted connection. You can ignore this message and proceed to the login IP address.The Login screen appears.
4 In Standalone mode, click the Visit Nebula button if you want to open the Zyxel Nebula Control Center (NCC) login page in a new tab or window. In Cloud mode, click the Go Now button. The NCC is a cloud-based network management system that allows you to remotely manage and monitor the Switch. See Mode Changing for information on changing your Switch to Nebula Cloud management.
5 Alternatively, click Login to log into the Web Configurator to manage the Switch directly.
In Standalone mode, the default user name is admin and associated default password is 1234.
In Cloud mode, use the Local credentials: password to login. The Local credentials: Password can be found in Site-wide > Configure > Site settings > Device configuration in the NCC portal. See the NCC User’s Guide for more information.
In Standalone mode, the default user name is admin and associated default password is 1234.
In Cloud mode, use the Local credentials: password to login. The Local credentials: Password can be found in Site-wide > Configure > Site settings > Device configuration in the NCC portal. See the NCC User’s Guide for more information.
In Standalone mode, the change password screen appears the first time you log in using the default password.
The allowed string length is 4 to 32 for the new password and should not contain [ ? ], [ | ], [ ' ], [ " ], [ , ], [ [ ], [ ] ], or [ space ].6 After setting the new password, close and restart your web browser. Enter the ‘https://DHCP-assigned IP’ in the URL field and press [ENTER]. When the login screen appears, enter the user name (default: ‘admin’) and new password.
When in Standalone mode, the Select Mode screen appears.
7 Select the Web Configurator in Standard Mode that has a complete set of configuration for network installation. Or select the Web Configurator in Surveillance Mode that has a set of menus specifically designed for users who are mostly using the Switch for configuring and managing PoE devices like IP cameras.
8 the Setup Wizard screen will appear after selecting the mode. You can use the Setup Wizard screen to configure the Switch’s IP, login password, SNMP community, link aggregation, and so on. When you finish configuring the settings, you can click the Apply & Save button to make the settings take effect, and save your configuration into the Switch’s non-volatile memory at once. Check the screens to see if the settings are applied.
Once you click the Finish button, the settings configured in the Setup Wizard screen will overwrite the existing settings.
Otherwise, click the Exit button. You can select the Ignore this wizard next time checkbox and click Apply & Save if you do not want the Setup Wizard screen to appear the next time you log in. If you want to open the Setup Wizard screen later, click the Wizard icon in the upper right hand corner of the Web Configurator.
9 If you did not change the default SNMP community values and enabled SNMP in SECURITY > Access Control > Service Access Control, a warning screen displays each time you log into the Web Configurator. Click SNMP to open a screen where you can change the SNMP community string, see Configure SNMP for more information. Otherwise, click Ignore to close it.
