How to install Hirschmann MS20/MS30 series industrial Ethernet switches?

Overview

The installation user manual for Hirschmann MS20/MS30 series industrial Ethernet switches (Release 14 03/2023 version) covers four major modules: equipment overview, safety specifications, installation process, basic configuration, maintenance, and technical parameters. It provides detailed instructions on the hardware composition of the equipment (basic module, media module, SFP transceiver, etc.), installation steps (DIN rail installation, wiring, DIP switch configuration), safety compliance requirements (ATEX, IECEx and other hazardous environment certifications), and technical parameters (power supply range of 18-60V DC, working temperature -40 ℃~+70 ℃, port type supporting 10/100/1000Mbit/s twisted pair/fiber ports). It also offers a global technical support channel to provide comprehensive guidance for equipment deployment and operation in industrial scenarios.

Inspection item operation content verification standard remarks

1. Check the integrity of the packaging: basic module x 1, terminal block (4-pin x 2/6-pin x 1), label x 1, installation manual x 1. There are no missing or damaged items during transportation (such as shell deformation or port damage). If accessories are missing, contact the supplier for replacement

2. Equipment model matching confirmation: The product code is consistent with the requirements (key verification: number of ports, temperature range, power supply range). The 6th and 7th digits of the code are equal to the required number of ports (08/16/24); 10th position=temperature range (S/T/E); 11th position=Power supply range (A/C/E) Example: MS30-1602-T-C-H corresponds to 16 100Mbps+2 1G, -40~70 ℃, 18-60V DC

3. Installation environment confirmation: 1. Environmental temperature: meets the equipment temperature level (S: 0~60 ℃; T/E：-40~70℃）； 2. Installation location: well ventilated, with a reserved space of ≥ 10cm above and below; 3. Hazardous environment: If it is an explosion-proof scenario, the equipment needs to be labeled with ATEX/IECEx. The environment should be free of condensation and strong electromagnetic interference; Dangerous environments must meet Class I Division 2/ATEX 2G requirements and avoid installation near heat sources (such as frequency converters) or areas with high dust

4. Essential tools and materials preparation: Phillips screwdriver, crimping pliers, wire stripping pliers; Materials: Cat5e and above twisted pair cables, fiber optic jumpers (matching port types), copper wires (≥ 1.5mm ²), and cable tie wires that meet specifications (75 ℃ copper wires); The type of fiber optic jumper is the same as SFP (such as LC single-mode jumper with SM SFP). Explosion proof tools are required for hazardous environments

5. Power supply preparation: Confirm that the power supply meets the requirements: 1 Voltage range (A: 18-32V DC; C/E: 18-60V DC); 2. Redundant power supply requires 2 independent power sources; 3. Class 2 power supplies with overcurrent protection (compliant with equipment fuse specification: 5A) are required in North America. DC power supplies need to distinguish between positive and negative poles, while AC power supplies need to be isolated and grounded

Hardware installation process (operated in sequence)

（1） Installation of media module/SFP transceiver

Common errors in step operation content verification standards

1. Remove the protective cap of the media module/SFP. The protective cap should not be damaged, and the port should be free of dust/metal debris. It is forbidden to touch the end face of the fiber optic port with hands

Align the basic module slot and insert the media module. Tighten the four corner screws to fully secure the module buckle. If the screws are not loose, install the module in the order of "left to right" to avoid slot misalignment

3 SFP transceivers are inserted into the gigabit slot, and the locking buckle makes a "click" sound when closed, making it difficult to easily remove. Only Hirschmann original SFP is used (third-party SFP may not be compatible)

（2） DIN rail installation

Step operation content verification standard safety precautions

1. Slide the top buckle of the device to a 35mm DIN rail (compliant with DIN EN 60715) and ensure that the buckle fully fits the rail without any looseness. The rail should be securely fixed to prevent the device from shaking

Press the bottom lock of the device and confirm that the device is fixed. Pull the device firmly without displacement. During installation, avoid squeezing the port and terminal block

（3） Grounding operation

Key requirements for step operation content verification standards

1. Choose grounding method: ① DIN rail grounding (priority); ② Special grounding screw grounding resistance ≤ 4 Ω. In hazardous environments, dual grounding (rail+screw) is required

If using screws for grounding, connect the grounding wire (with the same specifications as the power supply wire) and ensure that the grounding wire is not loose and in good contact with the shell. The grounding wire should not be laid in the same bundle as the power wire
