Transition Networks has introduced new, SNMP-managed switches designed for industrial Ethernet applications. In addition, the company has announced a number of feature and model enhancements to their portfolio of unmanaged industrial switches and media converters. Both the managed and unmanaged ruggedised devices are designed to operate reliably in harsh networking environments found on factory floors, outdoor enclosures or other hazardous environments, and are backed by a lifetime warranty.
The 8-port managed industrial switch series delivers management features via SNMP (simple network management protocol) for secure configuration and monitoring, including SNMP and SMTP e-mail trap support. Network traffic can be optimised and managed via port-based bandwidth allocation, port-based VLAN, 802.1Q VLAN tagging, IGMP snooping with query mode, 802.1p 4-level priority queuing, port trunking, port mirroring and packet filtering. Additional managed features include DHCP client support, SNTP (simple network time protocol) clock synchronisation, TFTP firmware update with system configuration restore and backup functions.
Critical communication needs are protected with the various redundancy features incorporated into these managed switches, allowing for increased reliability and system uptime. Redundant path communication is enabled via redundant ring switching technology with switching times of less than 300 ms, as well as utilising spanning tree protocol (STP) and rapid spanning tree protocol (RSTP).
To complement the redundant ring technology, the switches include coupling ring support for connecting multiple redundant rings in a network as well as dual homing support to ensure continuous connectivity to the core switches in the network. Redundant, auto-sensing, dual power supply inputs supporting 12 to 48 V d.c. provide instant swap-over support in the event of a failure of a main power supply, with both SNMP trap and relay contact closure notification.
The switches have a rugged metal enclosure which carries an IP31 rating. DIN rail bracket mounting and wall mount brackets are also included with each model.
