The PTS 740/746 series are designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613). 4 Gigabit Ethernet ports are ideal for building dual Gigabit redundant ring. The “Fi Ring” redundant Ring (recovery time < 20ms), RSTP and STP can increase system reliability and your network availability.

• PTS 740: 8×10/100BaseTX ports+2x100BaseFX+4x1000BaseX (SFP slots)
• PTS 746: 16×10/100BaseTX ports+4x1000BaseX (SFP slots)
• Command Line Interface (CLI) for quickly configuration major managed functions
• FMC Ring Protocol “Fi Ring” (recovery time < 20ms) and RSTP/STP for network redundancy
• IGMP snooping for filtering multicast traffic
• Port-based VLAN, IEEE 802.1Q VLAN, and GVRP to ease network planning
• Support port mirroring
• Support Access Control List (ACL)
• Rich QoS features for data traffic control and management
• Storm control for any combination of multicast, broadcast and DLF traffic control
• Port Trunk for optimum bandwidth utilization
• SNMPv3, IEEE 802.1X, HTTPS, and SSH to enhance network security
• SNMPv1/v2c/v3 for different levels of network management
• RMON for efficient network monitoring and proactive capability
• Bandwidth management prevents unpredictable network status
• Lock port function for blocking unauthorized access based on MAC address
• Automatic alarm through e-mail, relay output
• Works with FirstMile’s NMS FiVision (industrial network management software) for traffic monitoring and easy network troubleshooting
