1. Functional description
The 10/100BASE-T(X) ports of the switch represent a terminal
connection for the connected LAN segment. You can connect
single devices or complete network segments.
1.1 FRAME SWITCHING FUNCTIONS
Store and Forward
All data received by the switch from the system bus or at the
ports are stored and checked for validity. Invalid and defective
frames (> 1.522 byte or CRC error) as well as fragments (< 64 byte)
are discarded. The switch forwards the valid frames.
Multi address capability
The switch learns all source addresses per port. Only packets with
– unknown addresses
– addresses learnt at this port
– a multi/broadcast address
in the destination address field are sent to this port.
The switch learns up to 1000 addresses. This becomes necessary if
more than one terminal device is connected to one or more ports.
In this way several independent subnetworks can be connected to
the switch.
Learnt addresses
The switch monitors the age of the learned addresses. The switch
deletes address entries from the address table which exceed a
certain age (300 seconds).
Note: Restarting deletes the learned address entries.
Tagging (IEEE 802.1Q)
The IEEE 802.1 Q standard designates the VLAN tag to be included in a MAC data frame for the VLAN and prioritizing functions.
The VLAN tag consists of 4 bytes (2 bytes tag protocol identifier
TPID, 2 bytes tag control information TCI). It is inserted between
the source address field and the type field. Data packets with
VLAN tag are transmitted unchanged by the switch.
1.2 SPECIFIC FUNCTIONS OF THE TP/TX INTERFACE
Link control
The switch monitors the connected TP line segments for short-circuit or interrupt using regular link test pulses in accordance with
IEEE standard 802.3 10BASE-T/-100BASETX. The switch does not
transmit any data to a TP segment from which it does not receive
a link test pulse.
Note: A non-occupied interface is assessed as a line interrupt. The
TP line to terminal equipment which is switched off is likewise
assessed as a line interrupt as the deenergised bus coupler cannot
transmit link test pulses.
Auto polarity exchange
If the receive line pair is incorrectly connected (RD+ and RDswitched) polarity is automatically reversed.
Autonegotiation
Autonegotiation is a procedure in which the switch automatically
selects the operating mode of its 10/100 M12 ports. When a connection is set up for the first time, the switch detects the speed
(10 or 100 Mbit/s) and the transmission mode of the connected
network (half duplex or full duplex).
Autocrossing
The switch detects the transmit and receive pairs (MDI, MDI-X).
The switch automatically configures its port for the correct transmit and receive pins. Consequently it does not matter whether
you connect devices using a cross-over or straight cable.
1.3 FURTHER FUNCTIONS AND FEATURES
Reset
The switch will be reset by the following action:
– input voltages fall below a threshold
After a reset the following action is carried through:
– initialization
1.4 DISPLAY ELEMENTS
