2.5 Installing the Modular Managed Switch System

2.5.1 Connecting the Supply Voltage to the FL SWITCH MM HS

Head Station

24 V DC The system is operated using a 24 V DC voltage, which is applied at the head station. If

required, the voltage can also be supplied redundantly (see Figure 2-14).

Redundant 24 V DC supply

Figure 2-14 Supplying the system using two voltage sources

If redundant power supply monitoring is active (default setting), an error is indicated if

only one voltage is applied. A bridge between US1 and US2 (dotted line connection)

prevents this error message. It is also possible to deactivate monitoring in web-based

management or via SNMP.
