EtherWAN Smart PoE Watchdog: Your Network Guardian for 24/7 Reliability
In critical applications like smart cities, public safety, IIoT, and industrial automation, uninterrupted network connectivity is essential. Remote devices such as IP cameras or wireless access points are often installed in hard-to-reach areas and may experience software freezes or power glitches. These issues can disrupt operations and require costly on-site maintenance.
To address these challenges, EtherWAN offers the Smart PoE Watchdog — an intelligent, self-healing feature that keeps network devices online and operational 24/7. This functionality is available on all EtherWAN PoE switches, including Unmanaged PoE Switches and Managed PoE Switches, providing reliable power and connectivity for remote devices.
What is the PoE Watchdog?
The PoE Watchdog continuously monitors the link status of each Powered Device (PD). If a device becomes unresponsive for a defined period, the Watchdog automatically triggers a PoE power reset. This proactive mechanism eliminates downtime without manual intervention, ensuring maximum network uptime.
Key Features
- Automatic Recovery – Regularly checks each PoE-powered device and resets power if communication fails, preventing devices from hanging indefinitely.
- Port-by-Port Control – Enable or disable the Watchdog per port via DIP switches for precise, granular control.
- Flexible Reboot Options – Adjust Watchdog activation time (5 or 10 minutes) via DIP switch for a complete PD reboot.
- Product Integration – Built into all EtherWAN PoE switches, including unmanaged and managed models, for seamless deployment in various industrial environments.
Benefits at a Glance
- Eliminate Downtime – Devices recover quickly without service interruptions.
- Reduce Maintenance Costs – Fewer site visits and faster problem resolution.
- Simplify Network Management – Built-in intelligence keeps your network healthy with minimal oversight.
- Flexible Deployment – Compatible with both managed and unmanaged EtherWAN switches for easy integration.
