The no carrier portion of this message indicates that the device may have lost
the carrier detect signal. The driver has a test feature that verifies the Ethernet
cable connection between the device and the Ethernet hub. In order for this
feature to function correctly, the Ethernet hub must support the link test
feature and it must be turned on in the hub. If the hub doesn’t support the link
test or if the link test is disabled in the hub, you will see this error message
during the system boot.
The cable problem or hub link test disabled portion of this message indicates
possible cable problems. Check the cable, if no cable problem can be found
then check for a link integrity mismatch. If there is a link integrity mismatch,
you may enable the link test feature in your Ethernet hub (usually by turning a
switch on), or you may disable the link test in your SPARC system.
To enable/disable the link test: at the OBP’s ok prompt enter the OBP
command help ethernet and then press RETURN to receive more information.
The device did not find a transceiver. Check cabling and the transceiver.
