Advanced Suggestion
• Try to access the Switch using another service, such as Telnet. If you can access the Switch, check the
remote management settings to find out why the Switch does not respond to HTTP.
I can see the Login screen, but I cannot log in to the Switch.
1 Make sure you have entered the user name and password correctly. The default user name is admin,
and the default password is 1234. These fields are case-sensitive, so make sure [Caps Lock] is not on.
2 You may have exceeded the maximum number of concurrent Telnet sessions. Close other Telnet
sessions or try connecting again later.
Check that you have enabled logins for HTTP or Telnet. If you have configured a secured client IP
address, your computer’s IP address must match it. Refer to the chapter on access control for details.
3 Disconnect and re-connect the cord to the Switch.
4 If this does not work, you have to reset the device to its factory defaults. See Section 4.7 on page 59.
Pop-up Windows, JavaScripts and Java Permissions
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your device.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).
There is unauthorized access to my Switch through telnet, HTTP and SSH.
Click the Display button in the System Log field in the Management > Diagnostic screen to check for
unauthorized access to your Switch. To avoid unauthorized access, configure the secured client setting
in the Management > Access Control > Remote Management screen for telnet, HTTP and SSH (see
Section 59.6 on page 544). Computers not belonging to the secured client set cannot get permission to
access the Switch.
73.3 Switch Configuration
I lost my configuration settings after I restart the Switch.
