Ethernet Rate Limit, VLAN & QoS Built-In Power & Temperature Sensors Remote Optic Measurements (e.g. Launch Power & Sensitivity) Network Management (Web, SNMP, Console & Telnet) SM/MM & Bi-Directional SFP Optics Extreme-Temp(-40°C to 80°C) and Hi-Temp (-20°C to 70°C) Options IEC 61850-3, IEEE 1613, NEMA TS-2 Power:12 VDC, 24VDC, -48VDC or 115/230VAC  Description Ideal as a compact and feature-rich Switch solution for both industrial automation and commercial networks, the TC3340 2+2 Redundant Gigabit Ethernet Switch offers a wide range of advanced networking features including Redundancy, Rate Limiting, Full Management, Security and Industrial Hardened capability. The TC3340 can be configured to handle any media or bandwidth requirement and provides two 10/100/1000M-Base-T and two SFP 1000SX/LX ports.  It supports distances up to 100km and is available with a “one fiber, bi-directional” option to maximize fiber optic cable usage. Optical redundancy includes automatic switchover within 38msec. in the event of a fiber breakage or network device malfunction. Rate Control gives users, especially data service providers, the ability to control or limit bandwidth. For example, rates can be limited to 32Kb, 64Kb, 256Kb, 512Kb, 1Mb, 2Mb, etc.  Password protection, multiple user groups and IP Aliasing provide multiple security features. The Industrial Hardened version supports temperature ranges from -40ºC to 80ºC and meets or exceeds all pertinent industrial environmental specifications including IEC 61850-3, IEEE 1613, NEMA TS-2, etc. Management is accessed via Web, SNMP, Telnet, or Serial Console. Power and Temperature Monitoring helps the user verify functionality.  Configuration settings can be saved and loaded to simplify network administration, and firmware can be remotely upgraded. Virtual LAN (VLAN), QoS and Network Time Protocol (NTP) are supported. The TC3340 SFP ports support 850nm multimode and 1300/1550nm single mode. The UTP connectors are RJ-45, the SFP Copper connector is RJ-45 and SFP Fiber connector is LC. Standard temperature range is -10°C to 50°C. Optionally, the high-temp version ranges -20°C to 70°C. The optional extreme-temp version ranges from -40°C to 80°C.  Power source options include 12 VDC, 24VDC, -48VDC or 115/230VAC, and power redundancy is standard. TC3340 is available standalone or rack mount (up to 10 cards per Rack Assembly).
