3.2.1.1
SW1, SW2 - Auto/Manual Negotiation “AN/MAN”
When the DIP-switch is in the Left/Down Auto-Negotiate “AN” position (factory default), the Port
automatically determines the duplex and pause modes of the connecting fiber optic devices. If the connecting
fiber optic devices cannot provide the proper signal to indicate their own mode of operation, the DIP-
switch should be set to the Right/Up Manual “MAN” position. SW1 controls Port 1; SW2 controls Port 2.
NOTE: When the fiber optic ports operate in Auto-Negotiation mode, the ports advertise for Pause.
When the fiber optic ports operate in Manual mode, Pause is disabled.
