configuration(specially along with switches). Under certain conditions,(where the
connected device is half duplex and does not support full-duplex; or the connected device
does not support full-duplex properly) no full-duplex is better and the internal jumper
settings will permit this to be selected on a per-port basis.

The factory (default) setting is Auto-Negotiation on all RJ-45 ports and full-
duplex on fiber 100Mbps ports, which is generally popular. Auto-Negotiation on RJ-45
and FDX on fiber port works well under most circumstances, but cannot always be
depended upon to work as expected. If full-duplex will not function properly in your
setup, internal jumpers allow the speed and mode of the Q-Series Combo- quad ports to
be fixed, even if the attached device may or may not support full-duplex. This is
