Therefore, the default setting of auto-negotiation (copper ports) is generally desirable because it is widely used and allows for the connection of various devices without re- configuration. Under certain conditions,(where the connected device is full duplex and does not support Auto-negotiation; or the connected device does not support Auto-negotiation properly no auto-negotiation is better and the internal jumper settings will permit this to be selected on a per-port basis.

See Section 4.4 for additional information on auto-negotiation functionality.

The factory (or default) setting is for full-duplex on all fiber 100Mbps ports, which is generally popular. It works well under most circumstances, but cannot always be depended upon to wor as expected. If full-duplex will not function properly in your setup, internal jumpers allow the speed and mode of the LE14XXA-Series fiber 4-ports to be
