Compact design and minimum cabling

Belden introduces new Hirschmann™ OCTOPUS switches with integrated 24 or 110V power supply



Belden has added six new Fast Ethernet switches to the OCTOPUS range from its Hirschmann™ product series. Thanks to an integrated power supply unit these switches take up less space than designs with an external power supply and also require less cabling, which reduces possible error sources and thus increases the operational reliability of the connected terminal equipment. Three of the switches are unmanaged 10-port devices.

The others have nine ports and feature layer 2 basic software from Hirschmann™, incorporating a variety of management and security functions and fast redundancy methods. Both the 9-port and the 10-port switches are available with or without PoE functionality and either a 24V or 110V power supply unit. The PoE versions are fanless with additional cooling fins, which provide effective temperature management resulting in longer lifecycles. All six switches have robust, compact die-cast zinc housings and are designed to operate at temperatures in the range 40°C to +70°C. They also fulfill the EMC and fireproofing requirements of the European standards that govern use in rail vehicles.

The switches measure 184 x 189 x 70 or 184 x 272 x 77 mm (width x height x depth), depending on the design, and can be mounted on a wall or directly on the machine. Their protection ratings are IP67 (9-port version) and IP54 (10-port version) and they also feature a high level of EMC and vibration resistance. The Fast Ethernet ports (10/100 BASE-TX) have D-coded M12 connections. The PoE facility supplies 15W per connected terminal device, using the phantom power method in which the terminal equipment is powered via the same wire-pair that carries the data. This means that two-pair cabling systems can also be used. On the front of the unit are LEDs that display both device status and network status as well as correct function of the power supply.


The managed designs can be configured via an Ethernet interface using command line interface (CLI), DHCP relay agent option 82, HiDiscovery or V24 interface, or via the ACA11 autoconfiguration adapter. RMON, port mirroring and LLDP (Topology Discovery 802.1ab) are available for diagnostic purposes. Alarms are output via an additional signaling contact More detailed information can be accessed via a standard web browser or using convenient network management software such Hirschmann™ Industrial HiVision. SNMP V2c and V3 are also supported. Redundancy methods such as HIPER Ring, MRP and RSTP ensure a high level of 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.

With these new OCTOPUS series switches from Hirschmann™ Belden is offering optimum solutions for a variety of transport sector requirements. “The integrated power supply in conjunction with the high port density facilitates space-saving installation,” says Product Manager Rolf-Dieter Sommer. “This is particularly advantageous for applications on trains and buses that offer comparatively little space for such equipment.”
