OLUTION
Unable to Access the Web Page Firewalls must allow access on port 80 and 443 in order for the unit to operate
through a firewall.
•
Contact your system administrator and request port 80 and 443 access.
Login Failure Firewalls must be configured to allow connections using the Dominion SX
configurable port network parameter (Default 23). If the firewall does not allow
these connections, the applet indicates that the login has failed.
•
Contact your system administrator and request connections be allowed on
the configurable port.
SSL Security Warnings The unit embeds its Internet Address (IP) in its SSL certificate. Should the
firewall perform Network Address Translation (NAT), the SSL certificate will
not match the IP address recognized by the browser generating a security
warning.
•
This is normal behavior.
•
The warning message does not affect operation of the unit.

OLUTION
Login Failure To provide additional security, the unit login screen expires after 20 minutes;
therefore, all login attempts after this time period will fail. Reload the browser to
reset this timer.
•
Hold down the < Shift > key and click on the [ Reload ] button in your
browser. This will refresh the login screen from the unit itself (not from a
local cache) and allow login to the unit.
RADIUS Users The unit can be configured to support RADIUS authentication. Any user not
defined to be a local user is considered to be a RADIUS user when RADIUS is
enabled. Should the RADIUS server not be reachable for user authentication for
any reason, the unit will not allow the user to log on until the unit receives the
result of the authentication request from the RADIUS server.
•
Authentication may take up to 40 seconds. Please be patient and wait until
either the user successfully logs in, or the Authentication Denied message is
displayed.
