Auto-negotiation, for Fast Ethernet copper ports

The M agnum Quad-Series Fast Ethernet copper ports can be set for either fixed
100Mb speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u standard.

separately.
One frequently-used application for the Magnum Quad-Switch copper ports is
to connec t one of them using a fiber media converter to another Switch in the network
backbone, or to some other remote 100Mb device. In this case, it is desirable to operate
the fiber link at 100Mb speed, and at either half- or full duplex mode depending on the
capabilities of the remote device. Standard commercially-available Fast Ethernet me
