• Confirm that the computer running the NDU has a network connection. See the section on

the NSA’s LAN connection for related information.

• The computer running the NDU can only discover NSAs in the same subnet. NSAs

connected to the same switch or router as your NDU computer are usually in the same

subnet unless the router is doing subnetting or the switch is implementing VLAN.

• The Genie Backup program uses the same network port as the NDU to discover the NSA.

To avoid a port conflict, do not run the Genie Backup Manager at the same time as the

NDU.

V A non-admin user wants to change her password.

Non-admin users can change their passwords directly. See Section 2.5.7 on page 46 for details

on how to do that.

V I cannot see or access the Login screen in the Web Configurator.

• Make sure you are using the correct IP address.

• 192.168.1.3 is the default LAN1 IP address and 192.168.100.1 is the default LAN2 IP

address.

• 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 NSA.” on page 251.

• Check the hardware connections, and make sure the LEDs are behaving as expected. See

the Quick Start Guide and Section 1.1.1 on page 32.

• Make sure your Internet browser has JavaScripts and Java enabled.

• Make sure your computer is in the same subnet as the NSA.

• Reset the NSA to its factory defaults, and try to access the NSA with the default IP

address. See Section 2.7 on page 52 for detailed information on the reset button.

• If the problem continues, contact the network administrator or vendor.

V I can see the Login screen, but I cannot log in to the NSA.

• 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.

• Turn the NSA off and on.

• If this does not work, you have to reset the device to its factory defaults. See Section 2.7

on page 52 for detailed information on the reset button.
