Belden launches new ethernet managed switches

New switches are available with Fast Ethernet ports, four of which support Power over Ethernet

By CBR Staff Writer

Belden, a developer of signal transmission products for the industrial, enterprise, broadcast, building management and security markets, has extended its OpenRail Switch product family with the addition of a new line of Hirschmann RS22 and RS32 Fast/Gigabit Ethernet Managed Switches.

The new RS Series switches are available with Fast Ethernet ports, four (4) of which support Power over Ethernet (PoE). The uplink ports can be designated as RJ45 connectors and for any combination of optical fiber connectors, such as MTRJ, ST or SC. RJ45 or SFP ports (10/100/1000Base-TX).

The company said that by using Phantom Power Poe, four (4) ports support PoE power and data transmissions, using the same pairs in the cable that permits the use of 2-pair cabling systems. Since the switches feature integrated power management, the power supply is adjustable for each individual port.

In addition, the functions that can be managed by means of SNMP v1, v2 and v3, or TELNET, include redundancy mechanisms such as Rapid Spanning Tree and HIPER-Ring, access control according to IEEE 802.1x, filtering options per port, and Flow Control with Prioritisation.

According to the company, fan-less cooling and an optional redundant voltage supply provide high operational safety. The circuit boards are available with a conformal coating for protection against condensation. The status of the switches can be locally retrieved through signaling contacts, with detailed information accessible for display using a standard web browser.
