External Transceivers

Some external transceivers support multiple link capabilities, such as 100BASE-T4, 100BASE-TX, and 10BASE-T, but not auto-negotiation. In this case, the driver attempts to bring-up the link in the highest priority capability in the following descending order of priority:

■100BASE-T4

■100BASE-TX

■10BASE-T

To bring-up your external transceiver in a lower priority capability, you must configure the driver parameters to force the link to the desired mode.

Refer to your external transceiver documentation or the Platform Notes: The hme Fast Ethernet Device Driver document for more information on forcing the link mode.

When using an external transceiver with the Sun FastEthernet PCI Adapter, your system may not report the speed at which the link is operating, either 10 or 100 Mbps.
