Comnet CNGE24MSS2-OB 24-Port Managed Ethernet Switch with Optical Bypass
Overview
The CNGE24MSS2-OB is a 24-port all-gigabit managed switch designed for hardened surveillance and industrial network deployments. It combines 16 copper 10/100/1000 Mbps ports with 8 SFP slots (100/1000 Mbps, single-mode LC connectors) and built-in optical bypass functionality—the topology you need when your camera feeds must survive a single fiber cut without dropping the entire recorder connection. This is a managed Ethernet switch built to live in equipment racks from -40°C to +75°C, meaning it won't fail when your outdoor cabinet temperature swings 150 degrees across seasons.
Compatibility
Deploy this switch as the backbone for any NVR or surveillance network that mixes cameras and encoders across copper runs (CAT6/CAT6a up to 100m per IEEE standards) and fiber links (single-mode for longer runs, < 10km typical). The 24 all-gigabit ports eliminate per-port bottlenecks—each camera stream (4–12 Mbps H.265, 10–25 Mbps H.264) can have dedicated bandwidth without contention. SFP slots accept industry-standard single-mode LC modules, so you can extend camera distribution across campus fiber without proprietary licensing. MSTP and RSTP support integrate with existing enterprise spanning tree topologies; IEC 62439-2 MRP provides 30ms ring recovery for dual-ring redundancy—critical when one upstream link fails and cameras must stay online.
Installation Notes
Mount in a 19-inch rack (standard depth required; verify your cabinet clearance before ordering). DC or AC input power options allow flexible PSU integration—specify which voltage at procurement. Operating range -40°C to +75°C means no thermal derating in outdoor cabinets; MTU 9,600 bytes supports jumbo frames for lower CPU overhead when pushing 16+ simultaneous camera streams. Web-based and CLI management interfaces; both require network connectivity to the switch—ensure management VLAN or OOB link is planned during network design. Fiber SFP ports use duplex LC connectors (2 duplex / 4 simplex optical bypass pairs)—verify module compatibility with your fiber vendor before shipment.
