PCI 10/100Base-TX/3000 Quick Installation
Notes on Autonegotiation and Autosensing
If the PCI 10/100Base-TX/3000 card is connected to a device that does
not support autonegotiation or a device that has autonegotiation
disabled, the PCI card will autosense the speed of the link and set itself
accordingly. The duplex mode of the card will be set to half-duplex in
this case. If you want the card to operate in full-duplex mode, you must
set it using the method described in “Notes on Manual Speed and
Duplex Mode Configuration” in this document.
The PCI 10/100Base-TX card will sense when the connection between
itself and a hub or switch on the other end of a link has been broken. If
a connection is made to another (or the same) device and
autonegotiation is enabled, the autonegotiation and autosensing
process will be done again automatically. Autonegotiation and
autosensing are also done whenever the interface is reset.
