and Java enabled.
4 Make sure your computer is in the same subnet as the Switch. (If you know that there are
routers between your computer and the Switch, skip this step.)
5 Reset the device to its factory defaults, and try to access the Switch with the default IP
address. See
6 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.
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 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.
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
