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.”
