1+1 Failover Protection Switch
(Smart A/B Switch with Automatic Failover)



SafeComm-EF is an ethernet protection switch that provides 1+1 automatic ethernet failover protection between "primary” and "standby" terminals such as Servers, Switches and RTUs.

It monitors the active and standby terminal units in real-time and initiates switching based on user configurable parameters. The SafeComm-EN never becomes a point of failure even in power down condition, to ensure 99.99% up-time.

Key Features


Never becomes a point of failure (even when powered-down)

Fully User Configurable

User configurable link switching parameters

Real-time Clock with NTP Client

Real-time logging maintains a history of all events

Password Controlled Access

Maintain logs of access to the system

Local / Remote Access

Local Serial Port & Remote access through SSH / TELNET

Script Initiated Switching

Automatically initiates switching upon the receipt of scripted trap

Features and Highlights

  • Fail-Safe. Never becomes a point of failure. Automatically reverts to and reconnects the “primary terminal equipment” / even in a power down condition.
  • User configurable test parameters.
  • User configurable switching parameters.
  • Built-in real-time clock / real-time logging maintains a history of all events.
  • Serial Management Interface (USB) for local access.
  • Remote access over TCP-IP networks. Allows the user to access and carry out maintenance, or / and switch the links remotely, if required
  • Password Controlled Access. Maintains a complete log of all logins.
  • Script Assisted Switching. Automatically initiates switching upon the receipt of the scripted message / SNMP Trap.
  • Switching initiated through external triggers such as “Dry Contact Alarm Relays” of the connected terminal equipment.
  • Manual Switching through front-panel buttons with automatic front panel locking to prevent accidental switching.
  • The data connection through the Safecomm-E between the local area network and the WAN is completely transparent. The Safecomm-E is a failover switch and does not provide any data routing between its data ingress and data egress ports.


  • Enhances equipment availability and reliability.
  • Eliminates equipment downtime by automatically / seamlessly switch to the "backup” / “standby" equipment in the event of the failure of the primary/ active equipment.
  • Disaster Recovery. To provide automatic failover protection in mission critical applications requiring minimum equipment downtime.
  • To switch between and automatically re-route IP traffic to the “standby” terminal equipment upon the failure of the “primary” terminal equipment.
  • SafeComm-EF may be used to provide automatic fail-over protection and switching between two terminal equipment such as RTUs, SCADA Servers, Railway Signaling Equipment etc.
  • Automatic Test Feature. Concurrently tests both “active” and “standby” equipment, for “end-to-end” link and terminal equipment availability.
  • Alerts the user upon the failure or unavailability of any one of the two “active”/ “primary”, or "secondary” / “standby" terminal equipment.

SafeComm-EF providing 1+1 Network Protection

  • Provides 1+1 Ethernet Equipment Fail Over Protection
  • Failsafe: Never becomes a point of failure. Automatically reverts and connects to the primary equipment even in power down condition.
  • Fast automatic equipment switching upon equipment failure. Eliminates equipment downtime.
  • Completely eliminates re-routing of Ethernet cables. Ethernet cables are automatically moved to the available equipment port.
  • Essential for any application that requires 1+1 Terminal / Equipment redundancy such as Sub-Stations, Airports and Air Traffic Control Centers, Railway Signaling Networks and Industrial Installations etc., requiring minimum service interruption due to equipment failure.
  • Disaster Recovery.
