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 auto negotiation function is activated for the
POF port. Port monitoring is not activated for the two ports.
3.3.6.2
Functions of the POF interface
–
Line monitoring
According to standard IEEE 802.3, the switch monitors the connected fiber optic cables
for interrupts.
To prevent dirt from entering the connectors, do not remove the dust protection caps until
just before connecting the connectors. The same applies for the protective caps on the
connectors.
When connecting two glass fiber interface modules, note the signal direction of the fiber
optics. The fiber connection is always from the transmitter to the receiver.
The maximum length of the glass fiber cables depends on the fiber type used.
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.
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, a POF 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.
