3.3.7.1
Default upon delivery
When the interface modules are inserted, the auto negotiation and auto crossing functions
are activated for the twisted pair port, and the data transmission rate is set to 100 Mbps full
duplex for the HCS port. Port monitoring is not activated for the two ports.
3.3.7.2
Functions of the HCS interface
–
Line monitoring
According to standard IEEE 802.3, the switch monitors the connected fiber optic cables
for interrupts.
3.3.7.3
Functions of the twisted pair 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.
3.3.7.4
Network connection
See "FL IF 2TX VS-RJ ..." on page 3-10 and onwards, and "FL IF 2HCS 100 ..." on
page 3-15 and onwards.
If an interface module is inserted in a MMS that has already been parameterized, the
existing configuration remains active.
Ports that are not being used are considered cable interrupts. In addition, an HCS 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.
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.
