The 4-port 10/100/1000 Mb/s Intelligent Redundant Ring Gigabit Switch from COMNET features two 10/100/1000Base-Tx copper ports and two 100/1000Base-FX SFP ports. It provides various functions like DIP switch-based operation of RSTP for creating redundant network topologies, preventing network video flooding of multicast traffic when used in a linear or star topology, and more. The switch is fully compatible with the ComNet CopperLine SFP modules for operation over extended distance UTP or Coax cable.

RSTP (Rapid Spanning Tree Protocol), Multicast Flooding Prevention (in Star/Linear topologies only), and dual redundant SFP mode can be enabled without programming
Electrical ports support auto-negotiation for 10, 100, or 1000 Mb/s, full duplex or half duplex data
SFP ports are compatible with CopperLine CL-SFP modules and supports 100 or 1000 Mbps full duplex data
Automatic MDI/MDI-X crossover
Event notification through SNMP traps and relay output
Voltage transient protection on all power and signal input/output lines provide protection from power surges and other voltage transient events
Supports LLDP (Link Layer Discovery Protocol)
SNMP v1/v2c for network management
Designed to meet full compliance with the environmental requirements of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment
Redundant AC/DC inputs for uninterrupted operation in the event of a loss of operating power or a power supply failure
Can be DIN-rail mounted using ComNet DINBKT2 or DINBKT4 adapters (not included)
