Check the hardware connections, and make sure the LEDs are behaving as expected. See
2
on page 33.
Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java
3
enabled.
Make sure your computer is in the same subnet as the Switch. (If you know that there are routers
4
between your computer and the Switch, skip this step.)
Reset the device to its factory defaults, and try to access the Switch with the default IP address. See

Section 4.6 on page
If the problem continues, contact the vendor, or try one of the advanced suggestions.

Advanced Suggestions
• 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.
Make sure you have entered the user name and password correctly. The default user name is admin,
1
and the default password is 1234. These fields are case-sensitive, so make sure [Caps Lock] is not on.
You may have exceeded the maximum number of concurrent Telnet sessions. Close other Telnet
2
session(s) 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.
Disconnect and re-connect the cord to the Switch.

If this does not work, you have to reset the device to its factory defaults. See

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).
I cannot see some of Advanced Application submenus at the bottom of the navigation panel.
The recommended screen resolution is 1024 by 768 pixels. Adjust the value in your computer and then
you should see the rest of Advanced Application submenus at the bottom of the navigation panel.
