Auto negotiation
Auto negotiation is a method whereby the switch automatically detects the operating
parameters for the connected network and sets the corresponding parameters
(10 Mbps/100 Mbps data transmission rate and half/full duplex transmission mode) for
its F-SMA ports. Automatic port setting eliminates the need for manual intervention by
the user. The auto negotiation function can be activated/deactivated via the web
interface.

Auto negotiation
Auto negotiation is a method whereby the switch automatically detects the operating
parameters for the connected network and sets the corresponding parameters
(10 Mbps/100 Mbps data transmission rate and half/full duplex transmission mode) for
its RJ45 ports. Automatic port setting eliminates the need for manual intervention by the
user. The auto negotiation function can be activated/deactivated via the web interface.
–
Auto crossing
There is no need to distinguish between 1:1 and crossover cables, as the transmit and
receive cables are crossed automatically.
–
Auto polarity
The polarity is changed automatically by the switch if a pair of twisted pair receive
cables (RD+ and RD-) are connected incorrectly.
–
Line monitoring
The switch uses link test pulses according to standard IEEE 802.3 at regular intervals
to monitor the connected TP/TX cable segments for short circuits and interrupts.

Network connection
See "Assignment of F-SMA ports to the DIP switch" on page 3-14 and onwards, and
"Reducing the transmission power" on page 3-13 and onwards.
3.3.7
FL IF TX/HCS 100 ...
Auto crossing is only available if auto negotiation is activated.
Ports that are not being used are considered cable interrupts. In addition, a TP/TX path to
a deactivated termination device is also considered a cable interrupt, as the connected
device cannot send a link test pulse because it is switched off.
The switch position for transmission power reduction will only be indicated in the web
interface in future hardware versions.
Hot plugging
When inserting and removing interface modules, you do
not
have to switch off the supply
voltage. The interface modules are detected automatically and logged to the network
management.
