I forgot the IP address for the Switch.
1 The default in-band IP address in standalone mode is http:/ / DHC P- a ssig ne d IP (when connecting to a
DHCP server) or 192.168.1.1.
2 Use the NCC (Nebula Control Center) or the ZON utility to find the IP address.
3 If this does not work, you have to reset the device to its factory defaults. See
Section 4.8 on page 77.
I forgot the user name and/or password.
1 The default user name is a dmin and the default password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See

I cannot see or access the Lo g in screen in the Web Configurator.
1 Make sure you are using the correct IP address.
• The default in-band IP address in standalone mode is
http://DHCP-assigned IP (when connecting
to a DHCP server) or
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.
2 Check the hardware connections, and make sure the LEDs are behaving as expected. See Section 3.3
on page 47.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts 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
Section 4.8 on page 77.
6 If the problem continues, contact the vendor, or try the advanced suggestion.
Adva nc e d Sug g e stio n
• 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.
