Hirschmann MICE MS20/MS30 Installation and DIP Configuration

5.2 System Status LED

P1/P2 (green): Indicates whether each power input is normal (≥ 18V).

RM (green/yellow): Indicates the status of the ring network manager (green=active and redundant port closed, yellow=active and redundant port open, flashing=ring network configuration error).

RUN (green): The system is starting (flashing) or ready (constantly on).

RL1/RL2 (red/yellow): Signal contact status (red=contact disconnection alarm, yellow=manual mode).

Chapter 6 SFP Module Installation and Fiber Optic Connection

6.1 SFP Installation

The gigabit slot of MS30 (located on the left side of the basic module) and the MM4-4TX/SFP and MM4-2TX/SFP media modules all support SFP transceivers. During installation, remove the SFP dust cap and push the SFP (lock closed) into the slot until it clicks into place. Hirschmann certified SFP modules must be used (see attached list), otherwise they may be incompatible or affect explosion-proof certification.

Note: After inserting the SFP, the corresponding RJ45 port will be automatically disabled (both share the same channel).

6.2 Fiber optic transmission distance

Table 12-15 in the manual lists the transmission distance of each fiber optic module (including 3dB system margin):

Multimode (MM, 50/125 µ m, 1300nm): 0-5km (100FX) or 0-550m (1000BASE-SX, 850nm).

Single mode (SM, 1310nm): 0-30km (100FX) or 0-20km (1000BASE-LX).

Long distance (LH, 1550nm): 23~80km (1000BASE-LH) and even up to 176km (G2, LH+).

Bidirectional SFP requires pairing (Type A and Type B pairing).

Strict rules: LH can only be used for LH, SM can only be used for SM, MM can only be used for MM, and mixing is prohibited.

Chapter 7 Initial Configuration and Security Management

7.1 IP Address Acquisition

DHCP is enabled by default at the factory, and can also be configured through V.24 serial port (9600bps, RJ11), HiDiscovery protocol, BOOTP, or AutoConfiguration Adapter (ACA11/ACA21-USB). After the first power on, the device will automatically attempt to obtain an IP address. If DHCP is not available, it needs to be manually assigned through the serial port or HiDiscovery.

Default credentials: username user/password public (read-only), admin/password private (read-write). It is strongly recommended to change the default password after the first login (via web or CLI).

7.2 USB interface and AutoConfiguration Adapter

The USB interface (Type A, non isolated) is used to connect the ACA21-USB adapter and can batch load configuration backups or update firmware. This adapter can be plugged and unplugged during device operation, but attention should be paid to explosion-proof area restrictions (see next section).

7.3 Environmental temperature monitoring

The "internal temperature" displayed by CLI/GUI is about 20 ° C higher than the ambient temperature (5cm away from the device). The manual provides a maximum internal temperature threshold (such as 85 ° C), which triggers a signal contact alarm if exceeded. Ensure good ventilation during installation and maintain a minimum gap of 10cm between the upper and lower parts.

Chapter 8 Compliance Points for Explosion proof Areas (ATEX/IECEx)

The MS20/MS30 equipment holds ATEX, IECEx, and UL Class I Div 2 certifications (see control diagram 000160011DNR). When used in hazardous areas, it is necessary to comply with:

Temperature level T4: ambient temperature of 0-60 ° C (standard) or -40~70 ° C (extended).

Shell protection: The equipment is of open type and must be installed in cabinets with IP54 or higher.

Transient overvoltage limit: The transient overvoltage of the rated voltage shall not exceed 119V (special requirements).

Cable temperature: If the temperature at the cable inlet exceeds 70 ° C or the branch point exceeds 80 ° C, the temperature resistance level of the selected cable must be matched.

Non flammable on-site wiring parameters: relay contact parameters Vmax=30V, Imax=90mA, Ci=0nF, Li=0 μ H (maximum cable length needs to be calculated to meet L0 and C0 limits).

Prohibited live plugging and unplugging: All connectors (including SFP, media modules, power terminals) must be plugged and unplugged in the absence of power or explosive gases.

Chapter 9 Maintenance and Disassembly

Regular inspection: relay contact resistance (depending on the number of switches), ventilation hole cleanliness, software updates (available for download from the official website).

Dismantling equipment: Disconnect all cables, remove grounding, press the DIN rail lock and remove upwards.

Disassemble SFP: Open the latch and pull it out, then cover it with a dust cap.
