51.2 Switch Access and Login
I forgot the IP address for the Switch.
1 The default IP address is http://DHCP-assigned 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. The Switch must be
registered and added to a site in Nebula in order for it to be managed using Nebula.
3 If the Switch is removed from a site in Nebula, all the settings in the configuration file are reset to the
Nebula factory defaults except for the IP address. If you changed the default dynamic IP address to a
static IP address while the Switch was in a site in Nebula, the Switch will retain that static IP address after
you remove it from the site in Nebula.
4 If this does not work, you have to reset the device to its factory defaults. See Section 4.8 on page 67.
I forgot the user name and/or password.
1 The default user name is admin and the default password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See Section 4.8 on page 67.
I cannot see or access the Login screen in the Web Configurator.
1 Make sure you are using the correct IP address.
• The default IP address 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 40.
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 67.
