type and output of LED indication.
Power supply
From 9 V up to 36 V from the PWR connector.
2.3 Device interfaces
2.3.1 Gigabit Ethernet interface with PoE
The device has four 10/100/1000 Base-T ports and two 1000 Base-T Ethernet ports routed to
the industrial connectors M12 (LAN1…6). Switching of these ports is carried out on the basis of
Marvell Ethernet Switch 88E6176 and 2x Marvell PHY 88E1510 switches. Controller's architecture
is optimized to achieve high speed switching at minimum power consumption.
For LAN1 - LAN4 ports, the switch ensures automatic determination of transfer rate and
switching between data transfer modes 10Base-T, 100Base-TX and 1000Base-T. Auto-negotiation
MDI/MDIX is activated in all 6 ports.
The front panel is equipped with six Gigabit Ethernet ports, which
use this connector type. 4 of them (LAN1, LAN2, LAN3, LAN4) are
supplied with the controlled power supply PoE (see subsection
2.3.1.3).
Fig. 2-2: External view of LAN connector
Note
These connectors ensure device tightness only ready-fitted with
Harting har-speed M12 mating connectors or special plugs, which
are supplied in set with the switch.

LED is on when 1000Base-T interface is connected via this port. The relevant port number is
signed on the top of its LEDs. PWR LED indicates that the device is switched on.

Warning!
For port 5 and 6, Gbit LEDs are on apart from the connection of
1000Base-T, during connection of 100Base-T, but the port itself is
operating only in the 1000Base-T mode.
2.3.1.3 PoE power supply
This technology, together with data, enables the switch to transfer power supply to a remote
device via 2 Ethernet twisted-pair wires in accordance with the IEEE 802.3af standard, using the
method A. This standard allows power supply of devices with the voltage from 44 V to 57 V. The
device supplies power to external devices 48V ± 5%.
The IEEE 802.3af standard enables connection of 4 classes of devices, including those with
a power up to 15.4 W per channel, therefore a total load to all of the 4x PoE ports can’t exceed 62
W. Dependence of the maximum load on ambient temperature conditions is shown in the diagram
below.
Fig. 2-4: Dependence of the maximum total load to all ports on temperature conditions
Note
When connecting PoE devices with a higher power consumption,
special consideration should be given to the dependence of
maximum total load on ambient temperature, as well as on the
removal of heat from the device.
Operation of PoE microchip of the controller (TPS23841) can be carried out under control of
an external device, connected via an insulated I2C bus / SMBus via PWR connector, which
contacts purpose is described below.

over I2C bus / SMBus are supplied with CPC309 CPU Module (can be found on Fastwel FTP).
A. Control in Linux 2.6 OS
Control is carried out via write/read from controller registers (for more detailed information
see documentation for TPS23841). PoE.sh script demonstrates operation with device driver.
PoE.sh [port number] [command]
Numbers of the ports: 1, 2, 3, 4 or all in case when a command refers to all the ports.
Commands:
status –displays information on the port's status;
sensors or sensor –displays values of sensors in the table;
disable –disables a port;
enable –enables a port;
reset –reset and start of POR cycle of all the ports;
shutdown or turnoff, or poweroff –disconnects power supply of all the ports;

3.1 Safety requirements
When handling NM350, strictly follow the below safety requirements. Manufacturer shall not
be liable for any damages, arising out as a result of non-observance of such requirements.
Warning!
Turn off the system power supply before installation / removal of the
module. Violation of this rule can pose a threat for your health and
life, as well as could lead to system or module damages.
Warning!
Tightness of the device (IP65) is guaranteed only when
recommended mating parts and plugs are used on unconnected
connectors (para. 1.3).
3.2 Installation methods
NM350 allows two mounting types:
- Mounting to panel with the use of the mounting bracket from among the delivery checklist
(installation kit IMES.465921.001)
- Mounting to DIN-rail using the kit IMES.465921.002.
NM350 can be mounted on the panel, suing a special bracket, included into the kit of
mounting parts together with four screws, and supplied with the switch. In the same way, the
device is mounted onto DIN-rail, using the IMES.465921.002 kit of mounting parts.

4.1 Power consumption of NM350
The device uses power supply voltage in the range from +9 V to +36 V from PWR connector.
Consideration should be given to certain requirements, which are essential for ensuring
stability and reliability. In Table 4-1 and Table 4-2 contain values of the maximum allowable
voltages and currents, which if exceeded, could lead to module damages. Power supply sources,
which are to be used with NM350, should be checked in order to meet these requirements.

4.2 Compliance with safety requirements
NM350 corresponds to the general safety requirements imposed on IT equipment according
to the GOST R IEC 60950-2002.
4.3 Noise resistance of NM350
NM350 corresponds to resistance requirements to IT equipment against electromagnetic
interference according to the GOST R 51318.24-99 standard (CISPR 24-97).
NM350 corresponds to the requirements for the level of industrial RF interferences coming
from It equipment in accordance with the GOST R 51318.22-99 (CISPR 22-97).
4.4 Operation conditions
The device retains operability under the following climatic and mechanical effects:
