CNGE24MSS2-OB Comnet Hardened 24 Port Managed Switch (16) 10/100/1000Base-TX ports and (8) 100/1000 Base-T SFP Ports Single Mode LC Connectors with Optical ByPass

The ComNet CNGE24MSS2-OB is a Managed Ethernet Switch with sixteen 10/100/1000 Mbps TX ports and eight 100/1000 Mbps SFP* ports that use ComNet SFPs for fiber type, connector type and distance. This switch also includes two sets of bypass ports that ensure network integrity during power loss or maintenance.
