Manage App Instances with the Local Profile Server

The Local Profile Server (LPS) is a per-network-port toggle that allows a local operator to make limited configuration changes to a node adapter directly on the device, without requiring connectivity to Edge Infrastructure Services. When LPS is enabled on a port, a local operator can adjust that port’s configuration using the LPS endpoint on the device. When LPS is disabled, the port follows only the cloud controller configuration, and any local override is reverted. LPS is particularly useful for remote sites where network connectivity to the cloud controller might be intermittent. By keeping a management port accessible locally, a site technician can restore connectivity without needing access to the cloud controller.

​

How It Works

The LPS toggle is a per-adapter setting on each network port. When enabled, the port’s configuration source can be reported as LPS (meaning a local override is active) rather than Controller. The Network Environment tab on the node detail page shows the current configuration source for each port.

​

Configuration source values

​

Enable LPS on a Network Adapter

1. In the sidebar, select Infrastructure > Fleet > Nodes.
2. Select the node name to open the node detail page.
3. Select the Adapters tab.
4. In the Network Adapters section, locate the adapter you want to enable LPS on.
5. Toggle Local Port Config (LPS) on for that adapter.
6. Select Save.

The interface displays a warning when you disable LPS: disabling reverts the adapter to cloud configuration, overriding any active local setting.

​

Enable LPS During Node Onboarding

LPS can also be enabled during the Zero-Touch or Manual Onboarding wizard when configuring network ports in the network configuration step. Toggle Local Port Config (LPS) on for any port that should allow local management.

​

Check the LPS Configuration Source

1. Open the node detail page.
2. Select the Adapters tab.
3. Select the Network Environment sub-tab.
4. Review the Source column for each adapter to confirm the current configuration origin.

Use Case: Graceful Shutdown with a UPS

For nodes connected to an uninterruptible power supply (UPS), LPS enables a local operator or UPS management system to initiate a graceful shutdown when power loss is detected. When connectivity to Edge Infrastructure Services is unavailable, the local operator can use the LPS endpoint to trigger the Prepare Power Off action. This gracefully stops all application instances on the node before power is removed. After power is restored, the node restarts and all previously running application instances return to their previous state automatically. To initiate Prepare Power Off from the console (when connectivity is available):

1. Open the node detail page.
2. Select More actions from the header action menu.
3. Select Prepare Power Off.
4. In the confirmation dialog, select Prepare Power Off to confirm.

​

Use Case: Managing Node Profiles Locally

LPS allows local management of port configuration without cloud access. This is useful in the following scenarios:

• Remote sites with unreliable WAN connectivity.
• Maintenance scenarios where a technician needs to adjust network settings on-site.
• Environments with strict network policies that block management traffic during certain windows.

When a local override is active, the Network Environment tab shows LPS as the configuration source for the affected adapter.
