•The default IP address is 192.168.1.1.

•If you changed the IP address, use the new IP address.

•If you changed the IP address and have forgotten it, see the troubleshooting suggestions for I forgot the IP address for the Switch.

2Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 3.3 on page 43.

3Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java enabled.

4Make 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.)

5Reset the device to its factory defaults, and try to access the Switch with the default IP address. See Section 4.6 on page 53.

6If the problem continues, contact the vendor, or try one of the 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.

1Make 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.

2You 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.

3Turn the Switch off and on.

4Disconnect and re-connect the cord to the Switch.

5If this does not work, you have to reset the device to its factory defaults. See Section 4.6 on page 53.
