It provides four 10\/100\/1000Base-T(X) copper ports and two 100\/1000Base-FX SFP ports. The CNGE4+2SMS[POE][HO]\/M provides exclusive functionality for easy field deployment including DIP switch based operation of RSTP for creating redundant network topologies as well as preventing network video flooding of multicast traffic using IGMP snooping.\n\nPorts 1 through 4 can optionally supply up to thirty (30) watts of power per port based on the IEEE 802.3at standard. An optional High Output (HO) version is also available that can supply up to sixty (60) watts of PoE from ports 1 through 4. This product is fully compatible with the ComNet exclusive CopperLine® SFP modules for operation over extended distance UTP or Coax cable. The ComNet exclusive Port Guardian feature provides additional cyber security protection by enabling physical port lockout in the event that an existing cable is disconnected and prevents a potential network incursion using common spoofing techniques. The intrusion event is reported back to the operator using SNMP.\n\u003ch4\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeveral features can be enabled with no programming required: - RSTP (Rapid Spanning Tree Protocol) - IGMP V2 Snooping - Simple Multicast Flooding Prevention (Star\/Linear topologies) - Dual Redundant SFP Mode\u003c\/li\u003e\n  \u003cli\u003eSFP Ports support 100 or 1000 Mbps full duplex data\u003c\/li\u003e\n  \u003cli\u003eSFP Ports compatible with CopperLine CL-SFP modules\u003c\/li\u003e\n  \u003cli\u003eIEEE802.3at Power over Ethernet (PoE+)\u003c\/li\u003e\n  \u003cli\u003ePoE status monitoring \u0026amp; automatic reboot function\u003c\/li\u003e\n  \u003cli\u003eEvent notification through SNMP traps and Relay Output\u003c\/li\u003e\n  \u003cli\u003e30 W or 60 W PoE+ on Ports 1-4\u003c\/li\u003e\n  \u003cli\u003eRedundant AC\/DC inputs for uninterrupted operation in the event of a loss of operating power or a power supply failure\u003c\/li\u003e\n  \u003cli\u003eSupports Link Layer Discovery Protocol (LLDP)\u003c\/li\u003e\n  \u003cli\u003eSNMP v1\/v2c for network management\u003c\/li\u003e\n  \u003cli\u003ePort Guardian prevents network intrusion through intelligent physical port lockout\u003c\/li\u003e\n  \u003cli\u003eRSTP supported\u003c\/li\u003e\n  \u003cli\u003eIGMP v2 snooping supported\u003c\/li\u003e\n  \u003cli\u003eVoltage transient protection on all power and signal input\/output lines provides protection from power surges and other voltage transient events.\u003c\/li\u003e\n  \u003cli\u003eDesigned to meet 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 the Caltrans Specification for Traffic Signal Control Equipment.\u003c\/li\u003e\n  \u003cli\u003eElectric Port Supports Auto-negotiation for Full Duplex or Half Duplex Data Throughput\u003c\/li\u003e\n  \u003cli\u003eDesigned for wall or DIN rail mount installations (using optional DIN mounting bracket)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Comnet","offers":[{"title":"Default Title","offer_id":43247429025857,"sku":"C4-CN42SMSPM","price":1822.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/7488d026-1053415240_lg.jpg?v=1773113272","url":"https:\/\/www.fireandsafetyplus.com\/products\/comnet-cnge4-2smspoe-m-intelligent-redundant-ring-gigabit-switch-with-optional-poe-10-100-1000mbps","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
