• Performs faster than the Merge Synchronization mode with no conflicts to resolve

CAUTION: If you use the Overwrite option and specify an AMX switches database, you will lose the information

associated with any user and server groups that you have configured in the AMWorks software.

System limit dependencies

Due to the physical memory limits in the AMX switching system hardware, the following system

constraints have been imposed and will be enforced by the AMWorks software:

• Rule defining the maximum number of users allowed in the system.

• Rule defining the maximum number of servers allowed in the system.

• Rule defining the maximum number of records present in the system permission databases.

One record is defined as a user-to-server permission combination. The system can handle

65,536 permission records.

NOTE: The rule defining the maximum number of records present in the system permission databases affects

the rules defining the maximum number of users and servers. This means that the number of users times the

number of servers with permissions must be less than or equal to 65,536. An AMWorks software administrator

can define a large number of combinations within this limit.

User groups and server groups

A user group consists of a defined selection of associated users. This group (and therefore, all the

users in the group) can be given No Access, View Only or Full Access rights to individual servers.

A user can be a member of a number of user groups and can also be given different access rights to

a number of server groups. A user can also be assigned individual access rights to a server.

A server group is a defined selection of associated servers. Individual users can be given No

Access, View Only or Full Access rights to the server group (and therefore, all servers in the

group). A server can be a member of more than one server group and can also be given different

access rights from a number of user groups. A user can also be assigned individual access rights to

a server.

If a user is a member of two or more groups with different permissions to the same server, the

AMWorks software will always assign the highest privilege level to that server for that user.

Example of user groups and server groups

A new user joins the company. By default, when the user is added to the system, the user has no

access rights to any of the AMX switching system servers. The AMWorks software administrator

adds the user to the Employees user group, which has View Only access rights to all the servers in

the company. However, the new user needs full access rights to a small group of servers belonging

to the user's department. In this case, the administrator assigns the user Full Access rights to the

Accounts Servers server group. The new user will have the following access rights:

• When logged into the AMX user station, the user will have Full Access rights to the servers in

the Account Servers server group and View Only access to all other servers.
