1 Introduction
NM350 network switch represents a finished product equipped with six Ethernet channels,
designed for the use in data collection and processing systems, operating in harsh environments
and based on Gigabit Ethernet interface with a possibility to connect of up to 4 user devices with
support of PoE (Power over Ethernet) technology of power supply transfer over Ethernet data
transmission lines.
The device is supplied with power via D-Sub front connector using an integrated voltage
converter. If there are no connected devices, the board dissipates less than 9 W, which makes it
possible not to use additional external cooling.
Stability of NM350 network switch operation enables to use it in all industrial applications.
Components used as the basis for NM350, are carefully selected following applicability criteria in
embedded systems, which makes the module an optimal solution for the systems with a long life
cycle.
The User Manual contains directions for a proper and safe installation, powering-on and
configuration, connection and interaction of NM350 with external devices.
For proper operation of the module within the specified service life it is required to previously
look through the contents of this User Manual.
