High Availability (HA) pairs a primary (active) Litmus Edge device with a backup (standby) device that takes over automatically if the primary fails. This guide walks you through configuring an HA pair from Litmus Edge Manager and enabling it. 

:::hint{type="warning"}
**Note:** High Availability is currently available as a beta feature.
:::

## Before you begin

Before you configure a High Availability pair, ensure you have:

- Two Litmus Edge devices running Litmus Edge version 4.0.5 or later, both online and connected to Litmus Edge Manager
- Both devices have valid Litmus Edge licenses
- Litmus Edge Manager version 2.34.0 or later
- Decided which device will act as the primary and which will act as the backup

:::hint{type="info"}
**Note:** Configuring HA from Litmus Edge Manager lets you pair and manage devices centrally from a single location without logging into each device individually. Also see [High Availability (Litmus Edge Manager)](docId\:KDwX0Ah3k9b85DhuSsL0r) for overview and background information.
 HA can also be configured directly on each Litmus Edge device without Litmus Edge Manager. See [High Availability (Litmus Edge)](docId:6VCpUpiHFFAMQCgjeWeU6) in the Litmus Edge documentation.

## Step 1: Configure the HA pair

To configure the HA pair:

1. In Litmus Edge Manager, select a company and project.
2. From the navigation panel, select **Edge Devices**.
3. In the *Edge Devices* page, click the ID link of the device you want to configure as either the primary or backup node.
   .
4. the *Edge Devices* *Details *page, select the **High Availability** tab.
5. Toggle **Enable High Availability** to on.

6. In the *Configure High Availability* dialog, under **Select Role**, choose either **Configure as Primary** or **Configure as Backup**.
7. In **Select Peer Node**, select the paired device. Click **Next**.

8. In **Confirm IP Addresses**, verify that the primary and backup node IP addresses are correct. Click **Next**.

## Step 2: Enable High Availability

To activate the HA pair:

1. In the **High Availability** tab, click **Enable** in the top-right corner.
2. Review the confirmation message and click **Yes, Enable**.

High Availability is now active. The tab displays the current pair status and heartbeat information.

## Verify High Availability is working

To confirm the HA pair is configured and running correctly:

1. In the **High Availability** tab, confirm that **Sync Status** shows **Started**.
2. Check that **Peer Reachable** is **true** to indicate that the backup node is reachable from the primary.

If the pair status shows **Degraded** or **Unknown**, confirm both devices are online and running Litmus Edge 4.0.5 or later.

## Disable or delete an HA configuration

To deactivate HA without removing the configuration, click **Disable** in the **High Availability** tab.

To remove the configuration entirely, click **Delete Config**. Both devices return to an unpaired state.
