3.2.3.1 Default Upon Delivery
When the interface modules are inserted, the link monitoring function for the HCS ports is
not activated.
3.2.3.2 Functions
– Line monitoring
According to standard IEEE 802.3, the switch monitors the connected fiber optic
cables for interrupts.
3.2.3.3 Connecting the F-SMA Connectors
F-SMA is a standardized fiber optic connection. We recommend the use of easy to operate
F-SMA connectors with quick mounting connection from Phoenix Contact.
The connectors are secured on the interface module by manually tightening the screw
collar.
Figure 3-11 Connecting the F-SMA connectors
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.
An HCS port is set to 100 Mbps - full duplex. If an HCS port is removed, the port mode
is set to auto negotiation.
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.
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.
