Key Features

  • Environmentally hardened for direct deployment in difficult unconditioned out-of-plant and roadside installations.
  • Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and CALTRANS Traffic Signal Control Equipment Specifications.
  • Extended ambient operating temperature range: -40˚ C to +75˚ C (Functional to 85ºC).
  • 10/100 BASE-TX and 100/1000 BASE-FX compatible.
  • Uses SFP modules for fiber and connector type and distance.
  • Redundant power supply compatibility reduces possibility of single-point-of-failure for highest possible reliability.
  • IGMP Snooping V1/V2 for multicast filtering and IGMP Query V1/V2.
  • Port based VLAN (IEEE 802.1Q).
  • IEEE 802.3af Class 1 – 3 PoE.
  • Rapid Spanning Tree protocol (IEEE 802.1W).
  • Port Based Security.
  •  Bi-color LED status indicators confirm operating status.
  • Power Supply Sold Separately.
  • Lifetime warranty.

Product Description

The ComNet™ CNGE2FE8MSPOE Managed Ethernet Switch provides eight (8) 10/100 BASE-TX ports and two (2) 10/100/1000TX or 100/1000FX combo ports. The CNGE2FE8MSPOE is environmentally hardened and designed for use in difficult environments, and is available for use with CAT-5e copper or optical transmission media.

The 8 electrical ports support the 10/100 Mbps IEEE 802.3 protocol. It features auto-negotiating and auto-MDI/MDIX to assist installation. All 8 ports support IEEE 802.3af Class 1 – 3 based Power over Ethernet (PoE). Two ports are 10/100/1000 configurable for copper or fiber media by selected by optional SFP modules. These network managed layer 2 switches are optically (100/1000 BASEFX) and electrically compatible with any IEEE 802.3 compliant Ethernet devices.
