RS3 – Rugged MIPIOS® Managed Ethernet Switch
The RS3 is a rugged, IP67 stand-alone managed Fast Ethernet switch. It provides
eight Ethernet channels on M12 connectors.
The switch supports full-duplex and half-duplex operation with auto-negotiation,
high-speed non-blocking store-and-forward switching, Quality of Service (QoS)
support with four traffic classes IEEE 802.1p and three-level 802.1x security as well
as the logical segmentation of ports (802.1q VLANs). The switch is fault tolerant
and restores itself on its own: If a link is temporarily unavailable, frames can be sent
via backup/redundant links (spanning tree protocol / link aggregation) and no data
loss occurs. Its built-in test mechanisms make the RS3 an even more reliable
component in the communication system.
A service port is accessible at the front panel on an M12 connector, providing an
easy way to configure the switch. A command line interface is available via the
RS232 at the service port and over Ethernet via Telnet or Secure Shell (SSH). The
switch can also be configured via SNMP (version 3) and through its HTTP web
server. Additionally, the service connector can be used to attach an external dongle
to store or update the switch configuration. This makes it easy to exchange the unit
for service purposes.
The RS3 a member of the MIPIOS family of extremely rugged IP67 compliant
products designed for Ethernet connectivity and highly demanding applications,
e.g., for redundancy systems.
The industrial-grade unit is fully compliant with EN 50155 railway standard. All
components inside the enclosure are specified for -40..+85°C operation, thus
enabling the device for EN 50155 class Tx operation. Additionally, the device is e1
certified by the German Federal Motor Transport Authority. Convection cooling is
sufficient. There are no socketed components, hardening the box against shock and
vibration. The internal electronics are prepared for conformal coating.
The Ethernet switch is prepared for wall or DIN-rail mounting.

Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the board and
other components against damage from static electricity, you should follow some
precautions whenever you work on your computer.
• Power down and unplug your computer system when working on the inside.
• Hold components by the edges and try not to touch the IC chips, leads, or cir-
cuitry.
• Use a grounded wrist strap before handling computer components.
• Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.
• Store the board only in its original ESD-protected packaging. Retain the orig-
inal packaging in case you need to return the board to MEN for repair.

1.2 Pressure Compensating Valve
The sealed housing of the RS3 makes a pressure compensating valve necessary to
prevent stress on the unit’s housing seals. Its hydrophobic and oleophobic ePTFE
membrane protects from the unit’s interior from water and common automotive
fluids and resists blocking after contact with common automotive fluids. It protects
against contamination from dirt, dust, salt and road debris (down to 0.07 µm).
1.3 Earth Connection
An earth connection can be established via the respective screw hole on the right
side of the unit (below the pressure compensating valve). Use an M4 screw.

1.4 Interfaces
1.4.1 Power Input
The RS3 usually comes with an internal 24 VDC nom. (9 to 36 V) wide-range
power supply led to a 4-pin M12 connector. RS3 models models with other input
voltage ranges are also available from MEN to suit individual projects’ needs.
The internal power supply is EN50155 compliant which implies that it has a built-in
power-on threshold of 0.7xUn = 16.8 V. Once the unit is turned on, the input voltage
may drop as low as 9 V.
Connector types:
• 4-pin M12 connector, male, A-coded (CONEC "SAL-12-FSH4-P12-9" 43-
01066)
• Mating connector: e.g., CONEC "SAL-12-RK4-2/A1" 43-10020

1.4.2 Ethernet Interface
The RS3 comes with eight Fast Ethernet ports on 4-pin female M12 connectors.
Connector types:
• 4-pin M12 connector, female, D-coded (CONEC "SAL-12D-FKH4.2-P12-9"
43-01248)
• Mating connector: e.g., Harting 21032811405 R410925
Table 2. Pin assignment of the Ethernet 4-pin M12 connectors
Each of the Ethernet ports has its own MAC address etc.
The unique MAC address is set at the factory and should not be changed. Any
attempt to change this address may create node or bus contention and thereby render
the switch inoperable. The MAC addresses on the RS3 are:
•LAN1: 0x 00 C0 3A A0 xx x0 - 0x 00 C0 3A A3 xx x0
•LAN2: 0x 00 C0 3A A0 xx x1 - 0x 00 C0 3A A3 xx x1
•...
• LAN8: 0x 00 C0 3A A0 xx x8 - 0x 00 C0 3A A3 xx x7
where "00 C0 3A" is the MEN vendor code, "A" is the MEN product code, the
following four digits depend on the the serial number of the unit and the last digit
corresponds to the interface (’0’ to ’7’ for ports 1 to 8 respectively). "xx xx" is the
hexadecimal serial number of the product, which depends on your board, e. g. "0x
00 2A" for the serial number "000042".
Example: Port 2 of the unit with the serial number 0042 (0x 00 2A) has the MAC
address 0x 00 C0 3A A0 02 A1.
For the unit’s overall serial number please refer to Chapter 3.2 Finding out the
Board’s Article Number, Revision and Serial Number on page 22.

1.4.3 Service Interface (RS232 / I2C)
The service connector features an RS232 UART interface for maintenance
purposes. Further information about maintenance and configuration options is
provided in the documentation of the RS3 firmware.
An I2C connection is also available to connect an external dongle (available from
MEN) for easy dumping or uploading of configuration data.

1.5 Ethernet Switch
The RS3 uses a manageable 8-port 10/100Base-T switch component, the Marvell
88E6095. The switch provides 10/100 Mbits/s configuration possibility on each of
the eight Ethernet ports.
It is also possible to configure each port in half-duplex or full-duplex.
The device characteristics are:
• 8 external ports configurable as 10/100 Mbits/s
• MII interface
• Each external port is configurable in half-duplex or full-duplex mode
• Non-blocking wire speed switching
• Store-and-forward mode
• Auto negotiation
• Port mirroring
• Port monitoring
• Flow control
• VLAN support
• Automatic MDI/MDI-X crossover (all ports)
• Port based frame priorization
1.5.1 Configuration of the Switch
The RS3 loads the following standard configuration for all ports at startup:
Table 4. Default switch configuration at startup
All of the ports are individually configurable using an external dongle, a command
line interface (via RS232 through the M12 service connector, Telnet or Secure Shell
(SSH)), via SNMP (Version 3) or via the unit’s HTTP web server. Further
information about configuration options is provided in the documentation of the
RS3 firmware.

1.6 Front Panel Status LEDs
The standard RS3 features a total of 20 status LEDs at its front panel: Sixteen for the
Ethernet port status (two for each port), one for the supply status and three for the
service port status. The LEDs act as described in the following tables.
Table 5. Ethernet port status LEDs
Table 6. Power supply status LED
Table 7. Service port LEDs
The micro controller uses the service port LEDs connected to it to indicate the
reason for an error during startup. The status LED will blink or light up as listed in
Table 8, Error codes signaled via service port LEDs until the system is restarted or
completely powered off. The supported error codes are as follows:
Table 8. Error codes signaled via service port LEDs
"Slow" means blinking with a frequency of 1 Hz, "fast" means blinking with a

2.1 Mounting the RS3
The RS3 is designed for mounting using one of two mounting plates, a DIN-rail
mounting plate or a wall-mounting plate (available separately from MEN). To attach
the unit to the mounting plate, remove the detachable bezel at the sides of the front
panel to access the four holes (two on each side) reserved for the necessary screws
as pictured above and below.
