Comnet CNGE28FX4TX24MS2 Ethernet Switch - 28 Ports - Manageable - 2 Layer Supported - Modular - Twisted Pair, Optical Fiber - 1U High - Rack-mountable - Lifetime Limited Warranty - TAA Compliance CNGE28FX4TX24MS2

The ComNet CNGE28FX4TX24MS2 Layer 2 Managed 28 Port Ethernet Switch supports twenty-four 10/100/1000 BASE-TX ports and four 10/100/1000 BASE-TX or 100/1000 BASE-FX SFP Combo ports of Ethernet data. The four combination ports are 10/100/1000TX or 100/1000FX SFP* configurable for fiber type (multimode or single-mode), connector type and distance. Dual 48 VDC input power design ensures vital network capabilities with minimum downtime. Utilizing RSTP/STP (802.1w/1D) MSTP, and X-Ring redundant ring topologies, a network recovery time of <20 ms is provided for protection from network faults or temporary interruptions. The CNGE28FX4TX24MS2 is optically (100/1000BASE-FX) and electrically compatible with any IEEE 802.3 compliant Ethernet device and are hardened for use in harsh operating environments. Features STP/RSTP/MSTP supported Port lock to prevent access from unauthorized MAC address SNMP V1/V2c/V3 for secure network management Legacy ring allows the switch to be used in an existing ring of ComNet X-Ring enabled switches Low-profile 1-RU (1.75-inch) high rack-mountable chassis mounts within any standard 19-inch equipment rack Event notification through Syslog, E-mail, SNMP trap 56 Gbps Backplane for layer 2 traffic forwarding IGMP v2/v3 (IGMP snooping support) for filtering multicast traffic & Port Trunking for ease of bandwidth management RMON for traffic monitoring No fans or forced-air cooling; cooling via natural convection eliminates unreliable and troublesome fans/moving parts, with no periodic maintenance requirements. Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances (SFPs ordered separately). Designed 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.
