# POST Initiate Failover
<a name="set-up-redundancy-groups-initiate-failover"></a>

Initiate failover of the specified node. The node must be part of a redundancy group, must have an “active” role, and must be running a channel. The redundancy group must also have least one backup node.

When failover is initiated, the node becomes to "idle" and all its channels are moved to a backup node. That backup node become an active node.

To make the original node active again, associate channels with the node again (using the PUT Channel command) and change that node’s status to "active."
