9.5.5 Changing the IP Address of a Nucleus2 Controller
If the current IP Address of the Nucleus2 controller is known then it can be changed by using
the Workbench online editor.
If the controller IP address is not available a new one can be set (see section 10.2.5 for
details).
Nucleus2 2463 Router Control Module Navigate to:
ConfigurationItems | IP | IP[1]
• Number = 0
• DHCP = False - set to false for a fixed IP address
• Address = enter the new IP address of the controller
• Port = if blank then the network port will be the default value which is 2007
• SubnetMask = set to match the network
• DefaultGateway = if unknown or not required enter 0.0.0.0
9.5.6 Configuring Nucleus2 2463 Controller Replication
When two router controllers are fitted in a Sirius 800 router they work as a main and
redundant pair. The active controller in the pair sends the inactive controller data such as;
crosspoint status, module configuration and port configuration. This means if the active
controller fails the other controller in the pair has the latest information available to it at all
times. To enable this function each controller must be configured with the details of the other.
Nucleus2 2463 Router Control Module Navigate to:
ConfigurationItems | ReplicatedPeer
• Name = enter the name of the controller that will be the replicated peer as shown on
the Workbench configuration screen
• IPAddress = enter the IP address of the controller that will be the replicated peer as
shown on the Workbench configuration screen
• IPPort = if blank then the network port will be the default value which is 2007
• ConnectionState = True or False - this is a status and is read only
• Active = True or False - this is a status and is read only
• Changes will not take effect until the Nucleus2 controller has been reset. This
forces it to read the new IP Address from its config.xml file.
• If the controller is part of a replicated pair ensure that the other controller is edited
so that it has the new IP Address of it’s partner (see section 9.5.6 for details).
• Changes will not take effect until the controller has been reset.
• If two Nucleus2 controllers are fitted in a router then the second one must also be
configured for controller replication.
