Manageable switches

Hirschmann Automation and Control has released the RSR family of manageable switches. These switches, which are offered in a Fast (RSR 20) and a gigabit ethernet version (RSR 30), are designed to be resistant to shock and vibration and have high electromagnetic compatibility.

They also have a compact metal housing (125 x 140 x 120 mm) and can be mounted both on DIN rails and on the wall.

Other features include a temperature range of -40 to +85° Celsius and a power supply with 16.8-60 V (DC) or 48-320 V (DC) or 90-265 V (AC). For protection against condensation the circuit boards can be coated with a special protective lacquer (conformal coating) if desired.

The modular switches, which can be set up individually in different versions, have up to nine fast ethernet ports (100 Base-Tx/FX) and a maximum of three 1000 Base-Tx uplinks. Since the uplinks are designed as Combo-Ports, they can also be equipped with SFP Fibre modules (1000 Base-Fx/SX/LX/LH).

Redundancy methods such as Fast HIPER Ring, rapid spanning tree and link aggregation ensure high network availability.

The security mechanisms include access control in accordance with IEEE 802.1x, IP and MAC port security as well as SNMP v3 and SSH.

The fanless cooling and an optional redundant power supply also contribute to the high operational reliability. The status of the switch can be picked up by distributed signal contacts.

Detailed information can be displayed by a web browser. Another central management function is offered by the integrated SNMP interface which enables the use of network management software.
