12 CHAPTER 1: PRE-INSTALLATION
Figure 3 Network diagram - multiple servers
All servers in the pool use their eth0 interface to connect to the network.
Upgrades
Following the initial implementation, the system can be upgraded in
order to increase system capacity or provide database redundancy. For
example, adding a second server to a single-server implementation will
provide database redundancy.
Upgrades can be performed at any time on fully operational systems.
There is no need to disable any applications that are currently running
when you add a new server.
Post-installation
Setup
After you run the installation script and assign a role to the servers in your
network, you need to configure the following:
Setting up a Route to the Conference Servers
You must configure the VCX dial plan with a route to your conference
server pool. If your implementation has only one server, then a route to a
single endpoint is required. If your implementation has multiple servers,
then a route to multiple endpoints are required in order to provide
redundancy.
