Function 4: 4 Port Switch

The device is working as a standard 4 port switch. In this mode the device has two

10/100Base-TX and two 100Base-FX ports. All ports are having the same priority. The

switch is “outband managed” with the integrated management features for the rack

chassis.

Following Dip switches are available for the configuration of the ports:

DIP switch Port Function (ON/OFF)

1 1 (TP) ON: Autonegotiation OFF 100Mbit, full duplex

2 2 (FX) ON: full duplex OFF: half duplex

3 3 (TP) ON: Autonegotiation OFF 100Mbit, full duplex

Link Trough / ALM

The link status of each segment is forwarded, that means in case of a missing link on

one side, the link on the corresponding side is also switched (physically) off .

Attention: In idle state (no cables connected) there are no link signals send by the

bridge. This is no malfunction.

With activated ALM (Advanced Link Monitoring) the same port, which does not receive

a link signal, is also not sending an output link signal (loop back). This ensures that both

directions (transmit and receive) of the channel are having the same link status.
