Rugged Gigabit Ethernet switch for use in harsh environments

The M-Max SW21X/PS rugged Gigabit Ethernet switch from MicroMax is a ruggedized Gigabit Ethernet Layer 2+ managed switch rated for use in harsh environments including air, ground, or marine operation. The company says that a version rated for extended salty fog protection is also available upon request. The switch accepts a wide power supply voltage input and is tested and guaranteed over temperature range of -40 °C to +75 °C. In addition, its enclosure is designed according to the VITA 75 footprint, the standard for rugged small-form-factor enclosures for harsh environments. The part can handle maximum peak shock acceleration up to 40 g (11 ms) and complies with MIL-STD-810G (Method 516.6, Procedure V – the protocol for shock testing).

The M-Max SW21X/PS has up to sixteen 10/100/1000 Mb/sec copper twisted pair ports. Its control and management support is done through a web interface, while the host processor is accessed through a Command Line Interface (CLI). The embedded power supply complies with MIL-STD-1275D (for military vehicles) and MIL-STD-704F (for aircraft) specifications. The switch features IPv4 and IPv6 multicast group support and can handle eight priorities and eight QoS queues per port with scheduling.
