Frame-Switching functionalities
11.2.1
Store and Forward
All data received by a switch is stored and checked for validity. Invalid and faulty
data packets are discarded. Valid data packets are forwarded. Data packets with
a length of up to 1552 bytes are supported. The packet buffer size is 448k bits.
11.2.2
Multi-address capability
A switch learns all source addresses per port. Only packages with
▪ unknown addresses
▪ these addresses or
▪ a multi-/broadcast address
in the destination address field are sent to this port.
Up to 1000 addresses can be stored simultaneously. This is necessary if more
than one terminal is connected to one or more ports. This allows several
independent subnets to be connected to one switch.
Operation must be carried out by at least trained personnel.
Do not touch the housing during operation or shortly after switching off.
Hot surfaces can cause injuries.
Proper and safe operation of the product requires careful operation and
maintenance.
With the connection of the supply voltage you put the switch into
operation.
