• 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
1
user name is admin, 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 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.
