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.
