9 Maintenance and diagnostics
There are two maintenance and diagnostic applications available for NK8000 net-
works. One application (or tool), the NW8204 tool, is contained in the product in-
stallation CD. The other, the NK8000 Web Server tool, is available via Internet Ex-
plorer.
Note: The NK8000 Web Server tool is available for the NK8225 only if an
NS8210 driver in installed.
Both tools have the same NW8204 functionalities.
Note: There are slight differences in the NW8204 graphic user interface (installed
vs. Web).
In addition to the NW8204 tool, the NK8000 Web Server tool provides NS8210 and
NK822x diagnostic utilities. To the end user these tools appear to function in the
same way, however there are important differences (see details below and Fig.
33):
NW8204 is a password-protected Windows application that runs on a central
server, and can be installed on a networked PC. It offers maximum security,
whenever this may be matter of concern.
Web services, available for the central NS8210 driver, can offer a web browser
access, available anywhere on the network with no need of installing any soft-
ware. This approach, which requires the network connection, is faster and eas-
ier. Although the access to the web application requires a password, the secu-
rity is inferior to the one assured by the NW8204 application.

troubleshoot an NK8000 network and its components.
