Overview

If your Kerio Control hardware appliance (e.g., NG500) is housed in a rack or placed in a hard-to-reach location, you may want it to restart automatically after a power outage—whether planned (e.g., building maintenance) or unplanned (e.g., blackout). This includes both abrupt shutdowns and soft shutdowns initiated via the Kerio Control interface.

Problem

Kerio Control hardware appliances do not support automatic boot-up when power is restored. This means the device will not restart unless someone manually presses the power switch on the rear of the unit. For rack-mounted systems or remote installations, this can be problematic.

Solution

Although Kerio Control hardware boxes currently lack built-in auto-boot functionality, there are workarounds and best practices you can follow:

Workaround: Use a UPS (Uninterruptible Power Supply)

1. Connect your Kerio Control device to a UPS.

2. This ensures continued operation during short outages.

3. If the UPS battery depletes and the system shuts down, you can configure the UPS (if supported) to trigger a controlled shutdown and auto-restart once power returns.

⚠️ Warning: Avoid unplugging and replugging the power cable to simulate a restart—this may damage the hardware.

Summary

Kerio Control appliances do not currently support auto-boot after power loss. To mitigate this limitation, it's recommended to use a UPS to maintain power continuity and reduce downtime during outages.

FAQ

Q1: Can I enable auto-boot through BIOS or firmware settings?
A1: No, Kerio Control hardware appliances do not currently offer any BIOS or firmware option for auto-boot functionality.

Q2: Will the device restart if I use the shutdown option in the Kerio Control interface?
A2: No, if you shut down the device via the software interface, it will not auto-start when power is restored.

Q3: Is it safe to unplug and replug the power cord to restart the unit?
A3: No, doing so may lead to hardware damage and is strongly discouraged.
