Yes, but it's painful. It's the old Intel Ethernet chip. Not only that, but
for it to work at all on a sunray half the IOCACHE is devoted/wired for the 
onboard ethernet chips IO descriptors- and the IOCACHE has to set up for it to
work as the internal bus (moonshine) had latency problems IIRC.

A 'best bet' for quick porting turnaround is a multi-initiator SCSI
to another sparc machine, i.e.:

Sunray
NCR SCSI-3 Board
id 7 (natch) --- Stupid Slow Older Disk	
	     (an old PBox with a 600MB 5-1/2", e.g.), id 0
		|
		|
	     SparcStation (internal disk @ id 3)
	     with boot prom setting SCSI ID to 6.
