I purchased Safe@Office 110, but I only have Safe@Office 105
functionality. What should I do?
Your have not installed your product key. For further information, see
Upgrading Your Software Product on page 197.
I have exceeded my node limit. What does this mean? What should I do?
Your Product Key specifies a maximum number of nodes that you may
connect to the Safe@Office appliance.
The Safe@Office appliance tracks the cumulative number of nodes on the
internal network that have communicated through the firewall. When the
Safe@Office appliance encounters an IP address that exceeds the licensed
node limit, the Active Computers page displays a warning message and
marks nodes over the node limit in red. These nodes will not be able to access
the Internet through the Safe@Office appliance, but will be protected. The
Event Log page also warns you that you have exceeded the node limit.
To upgrade your Safe@Office appliance to support more nodes, purchase a
new Product Key. Contact your reseller for upgrade information.
