Comnet CNGE3FE8MSPOEHOK Industrial Managed Switch with PoE
Overview
The Comnet CNGE3FE8MSPOEHOK is an industrial-grade managed switch designed for hardened surveillance and remote site deployments where fiber uplink, copper PoE delivery, and extreme temperature tolerance are non-negotiable. It combines 3 SFP fiber ports (2 supporting up to 2.5 Gbps) with 8 RJ45 copper ports split into dual PoE tiers: 4 ports rated for 60W output and 4 ports for 30W output, totaling 360W PoE budget. The unit is built for environments from -40°C to +75°C operating range and mounts directly to 35mm DIN rail or wall surface — eliminating the need for separate enclosure or conditioning in remote cabinets, mobile command units, or outdoor equipment shelters.
Compatibility
This switch integrates with any standard PoE-capable IP camera (802.3af/at), network encoder, access control reader, or intercom supporting DC 48–57V input from a hardened power supply. The dual PoE tiers accommodate mixed-load camera deployments: allocate 60W ports to higher-power PTZ cameras or dual-feed edge recorders, and 30W ports to fixed-lens domes and turrets. The three SFP slots accept copper SFP modules or long-range single-mode fiber (SM) transceivers for redundant fiber uplink to distant NVRs or central NOCs — particularly valuable in environments where copper trunk lines are prone to EMI or where distance exceeds Cat6A practical limits. The CNGE3FE8MSPOEHOK kit includes two SFP-6 (likely SFP fiber modules) and a hardened 48V DC power supply with DRA480-48 designation for complete field-ready installation.
Installation Notes
Mount via 35mm DIN rail using standard industrial clipsets, or attach directly to cabinet wall using four fasteners (torque specs not provided in evidence — verify with Comnet technical support). Input voltage 48–57 VDC; verify your hardened PSU output matches this range before energizing. The unit's 1GB DRAM and 128MB flash handle 256 VLANs and 8K MAC table entries — more than sufficient for multi-site surveillance networks with subnet isolation and failover. Switching latency of 7 μS ensures sub-millisecond packet delivery across camera streams; jumbo frames up to 9.6K Bytes support high-bandwidth fiber trunk consolidation. Operating temperature range (-40°C to +75°C) and shock/vibration compliance (IEC 60068-2-27, -32, -6) meet outdoor and vehicle-mounted deployments. FCC Part 15 Class A and rail transit standards (EN50121-4) confirm compliance for fixed and mobile installations.
