PoE Octopus switches by Belden require less space than switches with an external power supply and are easier to install and maintain. Courtesy: BeldenBelden Inc. (NYSE:BDC), has added six fast Ethernet switches to the Octopus range from its Hirschmann product series. The integrated power supply unit takes up less space than designs with an external power supply and require less cabling, which reduces possible error sources while increasing the operational reliability of the connected terminal equipment.

Three of the switches are unmanaged 10-port devices. The others have nine ports and feature Hirschmann’s Layer 2 basic software, which incorporates 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 Power over Ethernet (PoE) functionality and have a 24 V or 110 V power supply unit. The PoE versions are fanless with additional cooling fins that 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 of -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 a 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 feature supplies 15 W 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. The front of the unit has LEDs that display 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 connected via an additional signaling contact. 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.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
