Gigabit Ethernet via M12 Ports
The new Gigabit OCTOPUS from Belden’s Hirschmann™ product range is a managed IP54 switch that was especially developed for road and rail vehicle applications that require fast data connection. To this end the switch has two Gigabit Ethernet uplinks for twisted-pair cables (1000 BASE-TX) connected via vibration-proof M12 ports. Eight Fast Ethernet ports (10/100 BASE-TX) are provided for connecting terminal equipment. These are also designed for M12 connectors and support PoE. They make it possible to power equipment such as IP cameras, Voice-over-IP phones or WLAN Access Points without the need for additional cables. The switch also offers various management and security functions plus fast redundancy protocols. It can thus be used to install high-availability Gigabit backbones in public transport vehicles, for instance giving passengers fast internet access during their journey.
This switch, which has an operating range of -40°C to +70°C, fulfils the EMC and fire prevention requirements of the European standards that govern use in rail vehicles. The fanless design and redundant 48V power supply also guarantee high operational safety.
The PoE facility makes use of the phantom power method in which the terminal equipment is powered via the same wire pair that carries the data, making it possible to use thinner cables and less complicated connectors. The power available to each terminal is 15W.
The switch, which comes in a robust and compact die-cast zinc housing (338 mm x 189 mm x 70 mm) designed for wall mounting, can be quickly taken into operation via plug and play. It can be configured using a command line interface (CLI), Telnet, BootP, DHCP option 82 or HiDiscovery, or via the ACA11-M12 auto configuration adapter. RMON, SysLog support and port mirroring are provided for diagnostic purposes. Alarms are output via an additional signalling contact and LEDs on the front of the housing display the unit’s status plus that of the network and the power supply.
Redundancy protocols such as HIPER Ring and rapid spanning tree ensure high network availability. The supported security mechanisms include IP and MAC port security, SNMP V3, SSH V3, SNMP access settings (VLAN/IP) and access control via IEEE 802.1x. More detailed information can be displayed via a standard web browser. The integrated SNMP interface offers additional centralized management functionality that makes it possible to use network management software such as Industrial HiVision from Hirschmann™.
This new Gigabit OCTOPUS is an innovative addition to the IP57 switches in Belden’s Hirschmann™ product series. “Gigabit ports with vibration-proof M12 connection technology are quite new,” says Product Manager Rolf-Dieter Sommer. “They enable high data rates to be reliably conveyed via twisted pair cables, making it possible to handle the steadily increasing network load in public transport vehicles with IP communications.”
