Safety Information
Before installation:
Read this manual completely and gather all information available on the product. Make sure it is fully understood. Check that your application does not exceed the safe operating specifications for the product.
SAFETY DURING INSTALLATION
The product must be installed and operated by qualified service personnel and installed into an apparatus cabinet or similar, where access is restricted to service personnel only.
During installation, ensure a protective earthing conductor is first connected to the protective earthing terminal (only valid for metallic housings). Westermo recommends a cross-sectional area of at least 4 mm2.
Upon removal of the product, ensure that the protective earthing conductor is disconnected last.
HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply. PROTECTIVE FUSE
The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply. Ensure compliance with national installation regulations.
RADIO PRODUCTS
Observe the usage limitations of radio products at filling stations, in chemical plants, and in systems with explosives or potentially explosive locations.
The product may not be used in airplanes. Exercise particular caution near personal medical aids, such as pacemakers and hearing aids. Never perform work on the antenna system during a thunderstorm.
To fulfill human safety, a minimum separation distance of 20 cm or more should be maintained between the antenna of the product and personnel during operation.
ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damage to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).

Product Description
Product Description
The MRD-415 and MRD-455 industrial cellular routers make full use of the 2G, 3G, and 4G cellular networks to cost-effectively inter-connect systems, sites, and operators. Creating a solid foundation for smart automated systems, where machines can communicate with machines and service technicians can remotely monitor and maintain their valuable assets in any system.
Devices connected to the Internet require countermeasures against cybersecurity threats. The MRD series offers protection of transmissions from malicious eavesdroppers via encrypted communication tunnels (VPN) and features a simple, yet powerful, packet inspection firewall. Configuration of the device is done with a simple and intuitive web interface, management is also available with a basic CLI, and SMS messages can be used for controlling the device and receiving status updates.
The products feature a built-in 2-port Ethernet switch for connecting to any Ethernet device. For legacy support, there is also a built-in serial port that offers a simple modem replacement solution with the benefit of not having to reprogram or change any other component.
Features such as connection maintenance and network to network roaming ensure very high availability and a connection that is always available. This is crucial in mission-critical installations, where even the shortest downtime can prove very costly.
The MRD-415 comes in a very slim and robust casing which is ideal for wall mounting in small spaces, taking up very little space in a cabinet or similar. Connections come out on each end of the product, with antenna connectors on one side and Ethernet and serial interfaces on the other. It features a very low power consumption, making it the ideal choice for battery or solar-powered applications. Low power consumption combined with a clever power-saving feature allows the unit to run for a long time without the battery.
The MRD-455 comes in a very compact and robust casing ideal for mounting on DIN rails. All connections and LEDs are located on the front, making it ideal for installation in industrial cabinets and applications. To further strengthen the already high availability, they feature dual-SIM card slots, allowing the user to remove carrier dependency and swapping operators automatically if the primary run into trouble. It also features galvanic isolation between all interfaces (power supply, Ethernet, serial), to protect the product against electrical surges and overvoltage, which is common in many industrial applications.

Installation
Mounting
This product should be mounted on a 35 mm DIN-rail, which is horizontally mounted inside an apparatus cabinet or similar. It is recommended that the DIN-rail is connected to the ground. Snap-on the product to the DIN rail according to the figure.
The MRD-415 includes an integrated mounting flange and can be attached to a panel or tray by means of screws, using the slots provided. Alternatively, it can be DIN rail mounted, using the DIN rail mounting kit.
Figure 5. Mounting of product
Power Supply
The MRD requires a DC power source in the voltage range of 10 to 60 VDC. The product is designed to self-protect from permanent damage if the voltage exceeds 60 VDC or if the reverse polarity is applied. The product may need to be returned for service if this occurs.
The product can also be damaged if there is any potential difference between the chassis ground, RS-232 signal ground, power (–) input, or antenna shield. Before connecting any wiring, ensure all components are earthed to a common ground point. An external isolator will be required if a positive earth power supply is used.
Antennas
The units have three antenna connectors (SMA). Please ensure that the connecting nut is done up tightly in order to make a good connection.
Protective Earth Connection
For correct function, the earth connection needs to be properly connected to a designated PE rail. See the figure below.
Figure 6. Earth connection
Cooling
This product uses convection cooling. Make sure that the unit is installed such as its ambient temperature is within its specified maximum/minimum temperature. Spacing is recommended for the use of the product in the full operating temperature range and service life. To avoid obstructing the airflow around the product, use the following spacing rules.
Minimum spacing of 25 mm (1 inch) above/below and 10 mm (0.4 inches) left/right of the product is recommended.
The product should be mounted in a clean and dry location, protected from water, excessive dust, corrosive fumes, extremes of temperature and direct sunlight. Allow sufficient ventilation to ensure adequate cooling of the product.

Getting Started
All configuration of the product can be done via the web interface. In order to view the web pages, a computer with a fixed IP address, on the same subnet as the product, will need to be connected to one of the LAN ports.
The default IP settings of the product are:
IP Address: 192.168.2.200
Netmask: 255.255.255.0
Note: The DHCP server of the unit is by default disabled.
Accessing the MRD
- Open a web browser on the PC and browse to http://192.168.2.200 (the default MRD IP address).
- A login box will pop up. If the box fails to display, re-check the cable connections to the unit and the IP address settings of the PC.
- Enter the following login details:
Username: admin
Password: westermo
The Status summary page will be displayed.
Factory Default Reset Switch
The reset switch is used to restore the configuration of the MRD to factory default settings. The switch is accessed through a small hole on the rear of the unit adjacent to the power connector.
To reset the configuration:
- Power down the unit.
- Use a suitable tool and depress the reset switch.
- Power up the unit ensuring the switch remains depressed for approximately 10 seconds after power is applied. The STS LED and NET LED will flash twice to indicate a reset.
- The router will now re-boot as normal with the factory default settings.
NOTE
Using the Factory default reset switch will erase all existing configuration settings and restore the factory default settings. This includes the network connection profile settings APN, user name, and password.
