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
1MB 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. 10 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 pin-out of the connected cable and
adapts the port accordingly. For all connections standard Twisted Pair cables can be used.
The Auto-negotiation mechanism automatically detects the speed and transmission mode (full or
half duplex) of all connected ports. 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 (LHB8000-PS). 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. 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. You need the optional Extended Firmware Package (LHB8200-
FW11) to have SNMP support.
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 CD-ROM.
With this tool it is also possible to do the initial TCP/IP setting (IP address, Gateway etc.) and
make changes afterwards.
Attention: The description for the initial settings can be found in the online manual!
The management information is available inside the network (in-band management). A separate
connection is not necessary, so all four twisted pair ports are available to connect other devices.
With the deactivation of the auto-negotiation function of the twisted pair ports the
configuration of the speed to 10 or 100 Mbps and full or half duplex mode is done manually.
