Belden Expands its Industrial Rugged Ethernet Switch Offering for Road and Rail Vehicle Applications with the New Hirschmann OS32 Octopus Series
These gigabit Ethernet switches make it possible to power equipment such as IP cameras, Voice-over-IP phones or wireless local area network (WLAN) access points without the need for additional cables. The switch also offers various management and security functions and fast redundancy protocols. It can be used to install high-availability gigabit backbones in public transport vehicles that give passengers fast Internet access during their journey.
With a temperature range of -40°C to +70°C, these switches fulfill EMC and fire prevention requirements of the European standards that govern use in rail vehicles. The fanless design and redundant 24V power supply also guarantee high operational safety.
The PoE feature 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) is designed for wall mounting and can be quickly put into operation using plug and play technology. These switches 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 signaling 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. Information that is more detailed 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.
This new Gigabit OCTOPUS is an innovative addition to the IP67 switches in the Hirschmann product series. “Gigabit ports with vibration-proof M12 connection technology are quite new,” says Hirschmann director of marketing Frank Wei. “They enable high data rates to be reliably transmitted via twisted pair cables, making it possible to handle the steadily increasing network load in public transport vehicles with IP communications.”
