ComNet CNGE20MS: Ethernet Switch, 20 Ports: 8 x Gigabit Electrical, 12 x Gigabit Fibre SFP Ports, Managed

Product Code: CN-CNGE20MS


The ComNet CNGE20MS is a 20-port managed Ethernet switch designed to reliably operate in harsh, environmentally challenging applications. It features eight 10/100/1000BASE-TX and twelve 100/1000BASE-FX SFP* ports. The SFP ports are 100/1000Mbps configurable for either multimode or single-mode optical fiber by the use of optional ComNet SFPs. Exclusive to ComNet is C-Ring, a feature that protects the network from interruptions or temporary malfunctions with fast recovery technology. Legacy ring allows the switch to be used in an existing ring of ComNet X-Ring enabled switches. Redundant DC inputs are included for uninterrupted operation in the event of a power supply failure. These network-managed layer 2 switches are optically and electrically compatible with any IEEE802.3 compliant Ethernet device.

  • Twelve SFP ports support 100/1000 Mbps SFP modules
