Compatibility and Installation Requirements
The limits of the current PCI 10/100Base-TX and 100Base-FX/9000 are:
• The PCI 10/100Base-TX/9000 card supports autonegotiation and
autosensing. You should not normally need to manually configure the
speed, autonegotiation, or duplex mode of the card. If your switch does
not support autonegotiation but is set to full-duplex mode, there may
be a mismatch between the card and the switch, because the card
defaults to half-duplex for switches that do not support
autonegotiation. You can determine what the card is set to using
lanadmin -x and reset it if necessary using lanadmin -X. See
"Manual Speed and Duplex Mode Configuration" on page 136 for
details.
By default, autonegotiation is on.
If you manually set the speed and duplex mode of the Base-TX card,
autonegotiation will be turned off.
The PCI 100Base-FX (fiber) card operates only at 100Mbits/s in either
full or half-duplex mode, but the fiber card does not support
autonegotiation.
• Both full and half-duplex modes are supported. If your hub or switch
does not support autonegotiation, ensure that your hub or switch is
set to the desired duplex mode.
• The PCI 10/100Base-TX and 100Base-FX/9000 LAN software is for
use with only the following protocols: TCP/IP, ARPA, and NFS.
• When using the ioscan -f command to verify installation, the last
digit of the H/W Path (hardware path) will show the port number of
the card. The other fields of the output will show the driver as btlan,
and the Hardware Type Description will show the product number of
each link card.
• The built-in PCI card for workstations has a nettl subsys_id of 173.
The built-in workstation card also uses a dynamic major number.
• On the built-in PCI card for workstations, the RJ-45 connector
operates at either 10 or 100 Mbits/s, but the AUI connector operates
only at 10 Mbits/s.
