    Console Messages (Solaris 1.x Only) The SunFastEthernet software can output the messages listed below. Each message is accompanied by an explanation and/or workaround. Some of the messages indicate normal operation of the product, while others indicate an error condition. In the latter category, certain messages indicate a transitory condition, while others indicate a condition fatal to the operation of the SunFastEthernet device.
  • Page 80 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.
