ZyXEL Communications NSA-2401 User Manual

Chapter 12 Troubleshooting

NSA-2401 User’s Guide

• 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.

address.

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