MEN Micro has expanded its MIPIOS line of rugged embedded modular computers and components to include two new IP67-compliant ethernet switches, the managed RS1 and the unmanaged RS2.
According to MEN Micro, each features eight ethernet ports on standard M12 connectors with support for both full- and half-duplex operation as well as non-blocking and store-and-forward switching with auto-negotiation. Layer 2 switching (IPv4/IPv6), quality of service (QoS) support with 4 traffic classes IEEE 802.1p and three-level 802.1q security and an 8K MAC lookup table with automatic learning and aging are also standard on the switches. Two redundant power supplies provide a nominal 24 VDC, with a 9 V to 36 V input voltage range.
The company said that the RS1 can be configured through an HTTP web server, a command line interface (CLI) such as RS232, Telnet and SSH, or an SNMP version 3. An external dongle can be connected to the service connector to store and update switch configuration. The RS2 can employ an application-specific EEPROM that enables it to act similar to a managed switch with fixed settings, giving it features atypical for an unmanaged switch, including port-based priority and VLAN.
The convection-cooled switches are fault-tolerant and automatically restore themselves, and the two power inputs enable the connection of a backup power source that automatically operates if the primary source fails. The switches also feature power over ethernet (PoE) power sourcing equipment (PSE) functionality to supply power to two additional devices on ports 1 and 2, the company said.
Each aluminum switch measures 8.7 inches x 5.1 inches x 2.8 inches. Operating temperature ranges from -40 degrees C to +70 degrees C, extendable up to +85 degrees C for short periods according to EN50155 class Tx. The switches have no socketed components for shock and vibration resistance. Pricing for the RS1 is $1,733 and RS2 is $1,153.
