# Refresh the connection between an enclosure and the appliance

If an enclosure has lost connectivity or is not synchronized with the appliance, you must refresh the connection. An enclosure can lose connectivity with the appliance during normal operation; it can become not synchronized with the appliance if you make changes to it through the OA or iLO. To prevent loss of connectivity, make changes to an enclosure through the appliance.

### Prerequisites

- Minimum required session ID privileges: Infrastructure administrator

Refreshing the connection between an enclosure and the appliance using REST APIs
`PUT /rest/enclosures/`{id}`/refreshState`

| NOTE: To track the progress of the refresh operation, use the `TaskResource` URI that is returned after the `PUT` operation. See Read the status of a task.
