4 FC7X00 CONFIGURATION
On the underside of the FC7x00 there are bit switches available for configuration of the
unit. The label shown below indicates which fibre interface module is fitted, and also
shows the functions and default positions of the bit switches.
Figure 4: FC7x00 Base Labels
The functions of the bit switches are described below:
4.1 Bit Switch 1: Auto Negotiation
This bit switch controls the auto negotiation operation on the 10/100BaseT twisted pair
interface. When Enabled the port will automatically negotiate with the far end to find the
highest common operation mode. When Auto Negotiation is disabled, the port speed and
duplex modes are configured manually according to switch 2 and 4.
SW1-ON
Auto Negotiation Disabled
SW1-OFF
Auto Negotiation Enabled
Note, that when the FC7x00 is connected to a non auto negotiating port, the auto
negotiation algorithm can only determine the speed of the link and will always select half
duplex mode. Thus when used with full duplex ports auto negotiation should be disabled,
and the speed and duplex selected manually.
