3.6.6 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 (Part No: 802-5333) for more information

on forcing the link mode.

Note – When using an external transceiver with the SunFastEthernet Adapter,

your system may not report the speed at which the link is operating, either 10

or 100 Mbps.
