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.
