1 Managed 8-Port Railway Ethernet Switch with PoERugged Embedded Network Box Fully Managed 8-Port rugged Ethernet Switch M12 D, A or X-Coded connectors on the front panel 10/100 (Fast) or 10/100/1000 Mbit/s variants 29 Gbit/s carrier grade switching matrix ITU Ethernet Linear/Ring Protection PoE+ power Sourcing Equipment (PSE ), up to 60 W output power Fanless and maintenance-free design Ultra wide range power supply input ( to 154 V DC) with interruption class S2 -40 C to +70 (+85) C with qualified components Compliant to EN 50155 ( railways ) Maintenance Free and Extremely RuggedThe NM31 family is a range of 8-Port fanless and maintenance-free Managed Ethernet switches, developed specifically for rough environmental conditions in rolling stock Speed, High Efficiency and Extensive ProtocolsThe NM31 range of Managed switches provide the additional ability to configure, manage and monitor the LAN which allows more control over how data travels through the network and who has access.

2 The use of the identical firmware as provided for the G101 Ethernet Switch , simplifies complex administration and reduces efforts for administrator Application PossibilitiesThe NM31 range provide eight channels at the front panel, accessible through M12 connectors and cover different application requirements including with or without PoE+, type 1 and type 2 (previously af and at) compliant, and either 100 Mb or 1Gb Ethernet to Railway StandardsThe voltage supply for the NM31 Managed Ethernet Switch is designed for maximum flexibility and supports wide range input supply voltages from to 154 V DC, and meets all EN50155 class S2 requirements for voltages ranging 24 to 110 CooledThe NM31 is designed for fanless operation at temperatures ranging from -40 to +70 C.

3 The NM31 features IP40 protection when surface-mounted and cooling fins which serve as a heatsink for the internal electronics, and in this way provides conduction Family ConceptAs a member of MEN's family of extremely rugged industrial box PCs, the NM31 provides the same flexibility and scalability, as well as a look and feel which is common to the SheetNM31 Data Sheet l 2017-12-11 Page M12 ConnectorsPower Supply ConnectorEarthing StudNM31 Data Sheet l 2017-12-11 Page DataSupported Port TypesnThe following configurations are available:o8x 10/100 BASE-T Fully Managed Switch with D-coded connectors, 8x PoE + PSE with max.
