Authentication
For security, the ETH-200 requires valid user authentication when the web
page is accessed or the point information is modified. The authentication
request will appear as a browser popup box that will request entry of a user
name and password. The unit contains two different security realms: an
administrator realm and a user realm. Each of these realms has a different
username and password, and applies to different activities. This division of
authentication realms allows a device administrator to retain control of critical
items (such as changing a unit’s IP address or modifying point values and point
definitions) while allowing a device user with appropriate authorization to
monitor point values (i.e. observe the status of the attached network devices).
Refer to Figure 18 for a screen shot of the administrator realm authentication
dialog box, and Table 1 for initial factory-set authentication values. Note that
the username and password are case-sensitive, and that once authenticated,
the authentication will remain in effect from that point until all browser windows
are closed.
