That's definitely a catastrophic component failure.
It appears that a SEEPROM chip on your V480 Centerplane has failed.
There would be no workaround except to replace the centerplane.
You may be in for an expensive repair if you don't have a service contract.
The only way to get an accurate diagnosis is to open a service case with Sun.
