and determine the maximum SSL bit strength for the
browser. If it is not at the desired strength, it is
recommended that the browser be upgraded.
In Netscape
®
, view Communicator > Tools > Security Info

Number of Users
Exceeded
The unit has a security measure that allows only a specific
number of login pages to be authenticated at any given
time. Should this number be reached when attempting to
login to the unit, a pop-up window displays indicating that
the maximum number of users is exceeded. This is normal
behavior for the unit.
Wait for a few minutes and attempt to login again. You
may need to refresh or <Shift+Refresh> your browser to
successfully log in.
Firewall
Problem
Solution
Unable to Access the Web
Page
Firewalls must allow access on port 80 (for http) and 443 (for https)
for the unit to operate through a firewall.
Contact your system administrator and request port 80 and 443, or
other custom configured ports for access.
Login Failure
Firewalls must be configured to allow connections using the
Dominion SX configurable port network parameter (Default 51000). If
the firewall does not allow these connections, the applet indicates
that the login has failed.
Contact your system administrator and request that connections be
allowed on the configurable port.
