# Genesys Quality Management Suite 8.1.520 : Servers

Created and last modified by

In multiserver deployments all individual servers should know about each other, they should be aware of the servers' IP addresses and the port based on the protocol it's communicating through.

By default there are two predefined servers:

1. AMQP Server - the server where the RabbitMQ broker is running
2. core - the default server that was defined during the installation process

## Adding a New Server to Your Cluster

Log in as admin. Navigate to Settings > Configuration > CallREC Core > Servers and scroll down.

The Servers screen displays all installed servers and ports. Define aliases at the bottom of the list to use in other configuration dialogs.

To add a new server:

1. Type the server details:

   - Server name - The unique label of the server within the cluster

   - Server IP address

     Icon

     If a server has multiple IP addresses (multiple NICs) and these IP addresses are involved in signalization, then each of the IP addresses need to be registered as a new server here.

   - Port
     The communication port of the protocol used for communication. Possible port numbers

     - 30400 - RMI port used for communication between all GQM services except Key Manager
     - 30401 - RMI port used for communication by the Key manager service
     - 5672 - AMQP port used for communication with the RabbitMQ broker
2. Click New.
3. Click Save configuration.
