Power supply / Alarm Contact
The power supply is done by an external power supply with an output voltage of 12 - 48 V DC.
The power supply unit is not included at delivery, but can be ordered separately (e.g. MS700420
24 V DC/24 W). The connection is done by the pluggable screw terminals on the top of the
device. The connection of a redundant power supply can be done by the second screw terminal.
In the following drawing the pin out of the power connector and the alarm contact is described.

The alarm contact is normally closed and opens if power input 1 or 2 fails.
RJ-45 / SFP Combo Ports
The switch provides two independent 10/100/1000Base-T / SFP Combo Ports. Both ports work
either on the SFP or on the RJ-45 interface. An inserted SFP module will disable the RJ-45 port.
The SFP port is capable to operate at different data rates. The selected data rate depends on the
inserted SFP transceiver. Gigabit Ethernet modules are automatically detected. They will work at
a data rate of 1000Mbps.
All other modules will work in the Fast Ethernet modus. It is recommended use only the
approved MICROSENS SFPs.
The RJ-45 ports have auto-crossing and 10/100/1000Base-T Autonegotiation capabilities.
Safety Notes
WARNING: Infrared radiation as used for data transmission within the fiber optic, although
invisible to the human eye, can nevertheless cause damage.
To avoid damage to the eyes:
•
never look straight into the output of fiber optic components – danger of blinding!
•
cover all unused optical connections with caps.
•
commission the transmission link only after completing all connections.
The active laser components used with this product comply with the provisions of Laser Class 1.
DANGER: Conductive components of power and telecommunications networks can carry
dangerously high voltage.
To avoid electric shock:
•
Do not carry out installation or maintenance work during lightning storms.
•
All electric installations must be carried out in accordance with local regulations.
