V 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 Turn the Switch off and on.
4 Disconnect and re-connect the cord to the Switch.
5 If this does not work, you have to reset the device to its factory defaults. See Section 4.6
on page 56.
V Pop-up Windows, JavaScripts and Java Permissions
