When you start the node replacement a DHCP server is started on the Corosync LAN interface of the active node. If the standby board which is connected to the Corosync LAN is rebooted or inserted, it will be booted and installed from the active node. This may last between half an hour and several hours depending on the load of the active node.

Standby node must be connected to the Corosync LAN via eth 4.
