In environments where network availability is mission-critical, inline security appliances like IPS, WAF and NGFW are essential to protect sensitive traffic. Their placement directly in the data path, however, can expose the network to interruptions during faults, maintenance cycles or unexpected power issues.
To address this, Microtel Innovation offers the HRB-140 High Reliability Optical Bypass Switch, a device that keeps network traffic flowing even when inline security devices experience faults that compromise their operation.
Fast Fail-Over
The HRB-140 continuously monitors connected appliances using bidirectional heartbeat packets. If a security appliance stops responding, its automatic fail-safe switching ensures that network links remain active and minimizes downtime even during unexpected appliance faults or power issues.
Bypass solution
The HRB-140 provides a bypass path that automatically maintains link continuity when a security appliance fails.
The internal Bypass Optical Switch implemented with MEMS (Micro-Electro-Mechanical Systems) technology guarantees very low optical insertion loss ensuring high-speed signal integrity and packets zero-latency insertion across all optical supported links.
The modular 1U chassis supports up to 8 links at 10/25 Gb/s or 2 links at 40/100/400 Gb/s, in single-mode or multimode fiber.
HRB-140 helps maintain traffic activity and ensures link continuity while supporting network resilience.
Remote management and path integrity
The HRB-140 provides a WebGUI that allows users to configure link modes, heartbeat settings, and network parameters. Administrators can manage users and roles, update firmware and the GUI, and monitor link status and heartbeat activity. Logs of system events are accessible and downloadable for review, while settings can be configured directly through the interface, enabling secure and controlled management of the device.
A safeguard for simplified network operations
With condition-based automatic operation and intuitive WebGUI control, the HRB-140 enables rapid isolation of malfunctioning security devices while keeping network traffic active, providing a stable and reliable foundation for inline security deployments.
