Gigabit Ethernet switch can support Power over Ethernet

Paul Boughton
Belden is introducing a MACH1040 gigabit Ethernet switch to complement its Hirschmann portfolio of networking products. With high-voltage resistance and inherent versatility, the switch offers high operational safety and network availability.
The IP30 Layer-2 switch, which can also be used as a router in combination with software to be available by mid-2010, has 16 gigabit Ethernet combination ports (1000 Base-TX) that will also connect SFP fibre optical transceivers (100/1000 Base-FX/SX/LX/LH). All ports support version 2 of the Precision Time Protocol (IEEE 1588 V2) as well as optionally Power over Ethernet (IEEE 802.3af).
Further characteristics include an operating temperature range of -40 to +70 degrees C, high resistance to jarring and extensive insusceptibility to electrical discharge and magnetic fields. Passive cooling and a redundant power supply help to ensure high operational safety. Furthermore, the new switch meets the standards and approval requirement of IEC 61850, IEEE 1613, EN 50121-4, EN 50155, cUL 508, cUL 1604 C1 Div2 and GL.
This makes the MACH1040 suitable for use particularly in extreme electrical environments, such as power plants and transformer stations. The combination ports facilitate the implementation of high-speed data networks of various topologies without additional investment costs for future retrofits or extensions.
The switch features energy-saving chip technology and has been designed for assembly on 19inch cabinets. Its rugged metal housing measures 448 x 44 x 310mm in width, height and depth. Boot time is only 10 seconds. By connecting an ACA 21-USB auto-configuration adapter to its USB port, all configuration data and the operating system can be saved and recalled at any time.
Alarm contacts are available for detecting the status of the switch. Detailed information can be displayed by means of a standard web browser. Further management functions include Command Line Interface, Management Information Base, Telnet, HTTP, TFTP as well as SFP Management. In addition, an SNMP interface permits the use of network management software, such as Hivision and Hidiscovery.
Product manager Jürgen Schmid comments: "The design of the housing, for the first time, combines 16 Gigabit combination ports with a temperature range of -40 to +70 degrees Celsius and fanless cooling. This permits the implementation of fast data networks with twisted-pair cables as well as optical fibres even in harsh EMI environments. Moreover, the hardware is already prepared for Layer-3 applications. An appropriate software update will be available next year."
