Hirschmann MACH102 Switch Installation and Power Supply Guide

Green constant light=link valid

Green slow flashing (1 time/cycle)=Port is in Stand by state

Green flash (3 times/cycle)=port managed to be closed

Yellow flashing=data transmission and reception

For PoE modules, there is also a yellow LED on the right side of each port, which is constantly on to indicate that the port is powered on.

Chapter 8 Initial Configuration and Security Enhancement

8.1 IP Address Allocation

By default, DHCP is enabled to obtain IP addresses at the factory. If there is no DHCP server on the network, it can be configured through the following methods:

V. 24 serial port (RJ119600bps, 8N1) using VT100 terminal to enter CLI

HiDiscovery/Industrial HiVision (Windows tool for discovering devices within the same broadcast domain)

BOOTP/DHCP Option 82

ACA22 USB adapter automatic loading configuration

Default management voucher (must be changed immediately):

Read only user: user/public

Read and write administrator: admin/private

Mandatory password change: After the software version update, the first login to the system will be forced to change the admin password to a new password (at least 8 characters, including uppercase and lowercase letters, numbers, and special characters). If you forget your password, you can reset it through System Monitor.

8.2 Common default parameters

V. 24 baud rate: 9600

HIPER Ring Redundancy: Disabled

Port link status monitoring (for signal contacts): disabled

100Mbps fiber optic port: forced 100M full duplex

Other ports: Auto negotiation enabled

RSTP (Fast Spanning Tree): Enable

Out of band management port (if present): IP 192.168.1.1/24

Chapter 9 Environmental Monitoring and Maintenance

The internal temperature of the device can be viewed through CLI/GUI, which is about 20 ° C higher than the ambient temperature (5cm away from the device). The technical data provides the maximum internal temperature threshold (+95 ° C), exceeding which may trigger a signal contact alarm. If the equipment frequently overheats, it is necessary to check the ventilation or reduce the temperature of the cabinet.

Maintenance suggestion:

Regularly check if the ventilation holes are blocked (depending on the level of dust on site)

Regularly check the contact resistance of the relay (which increases with the number of switches)

Regularly visit the official website to check firmware updates

The built-in fuse of the device is non replaceable and will be returned to the factory in case of damage

Chapter 10 Disassembly and Disposal

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

Dismantling the media module: First disconnect the PoE power supply (if applicable), unscrew the fixing screws, pull out the module, and reinstall the protective cover.

Disassemble the whole machine: Disconnect all cables (first disconnect the signal line, then disconnect the power supply, and finally disconnect the ground wire), and remove the bracket fixing screws from the rack or wall.
