•
If the LED is amber, the SunFDDI/P driver is loaded, the pf interface is
configured, but no valid line state to an active FDDI network exists.
a. Check the physical connections between the station and the ring, or
the station and the concentrator.
b. Check the status of the neighboring station.
If this station is down, it will bring down the link between the stations.
•
If the LED is red, the adapter failed the FDDI path test.
• If no LED is lit, either the SunFDDI/P driver is loaded and the interface is
not configured, or the driver has not been loaded.
•
a. Configure the pf interface with the ifconfig(1M) command of the
form:
•
If the LED is red, the SunFDDI/P driver is not loaded, or is loaded

a. Check that the software is installed.
b. Remove the existing version, if necessary, and reload the software.
Checking the MAC Address
By default, the first SunFDDI/P interface installed in the machine adopts the
host-resident Media Access Control ( MAC) address stored on the
motherboard. Each subsequent SunFDDI/P interface takes the card-resident
MAC address stored in its IDPROM.
