Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.
Port-based and IEEE 802.1Q VLAN
GARP (Generic Attribute Registration Protocol) and GVRP (Generic VLAN Registration Protocol) for segmentation of large networks into smaller parts and separate broadcast domains.
Firmware Auto Backup
Auto backup of firmware to the secondary memory and activation of it from there in case of loss of the primary memory.
Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.
Efficient Network Monitoring and Management
SNMP (Simple Network Management Protocol) and SFP DDMI (Digital Diagnostics Monitoring Interface) for traffic management and monitoring.
Efficient Traffic Prioritization
Effective QoS mechanisms for priority assignment, transmission of dedicated traffics to specific applications, and allocation of appropriate bandwidth to mission-critical communications.
Redundant Ring for Fast Recovery
Xpress Ring for detection and recovery of link failure in milliseconds.
