HIRSCHMANN PowerMICE series industrial Ethernet switches

North American market requirement: The device must be connected to a power source that meets NEC Class 2 requirements. If redundant power supply is used, the combination of two power sources must also meet Class 2 requirements and only use Class 1, 75 ° C copper wires.

Installation and Debugging Guide

The manual provides a detailed step-by-step installation guide to ensure that the equipment can be put into operation correctly and safely.

4.1 Mechanical Installation

DIN rail installation: The device can be easily mounted onto a 35mm DIN rail (compliant with DIN EN 60175). During installation, hang the card slot on the upper part of the device into the guide rail, and then press the lower part of the device towards the guide rail until it clicks into place. The lower panel of the device can be grounded through DIN rails or through independent grounding screws.

Media module installation: The media module supports hot swapping and can be installed while the device is running. Insert the module into the slot from left to right and tighten the screws at the four corners during installation.

Expansion module installation: The MB-2T expansion module also supports hot swapping. When installing, first remove the side panel on the right side of the basic module, then push the expansion module towards the basic module along the DIN rail until they are plugged together, and finally tighten the screws to secure it.

4.2 Electrical Connections

Power and signal contacts: The power and signal contacts are connected through two 4-pin pluggable terminal blocks. The manual emphasizes the importance of using the accompanying Z-shaped metal sheet and M2.5 screws to secure these terminal blocks. The redundant power input is decoupled, and the equipment is powered by a higher voltage power source. The signal contact is a passive relay contact used for remote diagnosis, which can report various events such as power failure, equipment failure, link interruption, and ring network redundancy failure.

PoE power supply: The MM22 PoE media module needs to be connected to an external 48V DC power supply through a 3-pin terminal block (recommended to use Husman RPS60/48V EEC power supply). When connecting, it is necessary to ensure that the length of the power supply line is less than 3 meters and the wire diameter meets the 1.5A current carrying requirement.

4.3 DIP switch configuration

The 6-pin DIP switch at the bottom of the device is used to quickly configure critical redundancy and startup functions without entering the software interface.

Switch 1 (RM): Turn on/off the redundancy manager function.

Switch 2 (Ring Port): Select the ring network ports that make up HIPER Ring (default to ports 1 and 2 of module 1; switch to ports 1 and 2 of module 2 when turned on).

Switch 3 (Stand by): Turn on/off the standby coupling function.

Switch 4 (HIPER Ring): Global enable/disable HIPER Ring function. When closed, the ring network port can be used as a regular port.

Switch 5 (Software configuration/DIP configuration): Choose between software configuration or DIP switch configuration. The default position is OFF, indicating that software configuration takes priority.

Switch 6 (Service): Switch the device to service mode.

4.4 Data Cable Connection

The manual provides detailed instructions on the connection methods and pin assignments for various ports.

10/100 Mbit/s TP port: RJ45 or M12 connector, supports Auto MDI/X, pin allocation conforms to MDI-X mode.

PoE port: RJ45 connector, apply 48V PoE voltage through pins 4, 5 and 7, 8 (idle line pairs).

Gigabit TP port: RJ45 connector, supports 1000BASE-T, pin allocation complies with MDI-X.

Fiber ports: Use DSC, ST, MTRJ, or SFP connectors. It is necessary to ensure that the port types match (such as LH to LH, SX to SX).

AUI port: used to connect traditional devices that comply with IEEE 802.3, via a 15 pin Sub-D connector.

Rich status display and basic settings

5.1 LED status indication

PowerMICE provides three layers of LED indicator lights, which greatly facilitate on-site fault diagnosis.

Device status LED: displays power status (P1/P2), redundancy manager status (RM), system operation status, relay alarm status (RELAY1/RELAY2), etc.

Display status LED: By using the "SELECT" button on the basic module, the display meaning of the media module port LED can be switched, such as displaying link/data status (L/D), duplex mode (FDX), transmission speed (1000), auto negotiation status (AUTONEG), ring port allocation (RING PORT), etc.

Port status LED: Each port corresponds to a dual color LED, and its display content is determined by the "display status", which can indicate link establishment, data transmission, speed, duplex mode, and PoE power supply status.

5.2 Basic Settings and Interfaces

IP address configuration: IP parameters need to be configured during the first installation of the device. Support configuration through various methods such as V.24 serial interface, HiDiscovery protocol, BOOTP, DHCP, DHCP Option 82, and AutoConfiguration Adapter.

Default setting: The factory default IP address is obtained through DHCP; The management password is user/public (read-only) and admin/private (read-write); V. 24 interface speed of 9600 Baud; The ring network redundancy and backup coupling functions are disabled by default.
