Sensitivity:

Wavelength:
1300 nm
Mounting
The switch is housed in a solid metal box with an integrated fixture for the installation on
standard 35 mm DIN EN 50 022 rails.
The fixation of the MICROSENS switch on the rail is done with a locking pin that can be
opened from the bottom side. If multiple devices are mounted in line, a minimum space of 20
mm should be kept between the devices, to ensure a sufficient heat dissipation.
Switch Features
The integrated switch has a store-and-forward architecture and can transmit all packets non-
blocking between the five ports at full wire speed. For data buffering the switch incorporates
1MBit of memory.
Up to 4096 different MAC addresses can be stored simultaneously in the internal switch address
tables. An automatic aging mechanism updates the tables max. 5 min. after the last reception of
data.
Twisted Pair Connections
The integrated auto-crossing function of all Twisted-Pair ports makes the use of crossed patch
cables unnecessary. The switch automatically detects the pinout of the connected cable and
adapts the port accordingly. For all connections standard 1:1 Twisted Pair cables can be used.
The Autonegotiation mechanism detects automatically the speed and transmission mode (full or
half duplex) between connected ports. A manual configuration is not required.
Power supply
The power supply is done by an external power supply with an output voltage of 24 V DC. This
power supply is not included at delivery, but can be ordered separately (MS700405). 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.
Management
The integrated http server offers to show status information by using a standard internet
browser. A special configuration is not necessary. Additional to the web based management the
switch offers a MIB to be used in all standardized Network Management Systems (NMS)
supporting SNMPv1 protocol.
With the PC based management tool Device Manager it is possible to configure all ports of the
switch manually. Please refer to the online manual for the Device manager on the disk.
With this tool it is also possible to do the initial TCP/IP setting (IP address, Gateway etc.). This
configuration can be changed afterwards using the TCP/IP protocol.
Attention:
The description for the initial settings can be found in the online manual!
The management information are available inside of the network (inband management). A
special connection is not necessary. Due to this all four twisted pair ports are available to
connect other devices.
With the deactivation of the autonegotiation function of the twisted pair ports the
configuration of the speed to 10 or 100 Mbit/s and full or half duplex mode is done manually.
