SCSI help sun 3/180

[Robert K.A.W. Henkel]

We have a few SCSI cards that I need to get working in a 3/180 server.
The SN number of the cards are: 501-1217 , under that tage is a 501-1220.
The card works fine in a 4/280 but I can't get it to work in my 3/180.  I
do have a 501-1167 working fine in a 3/180 (SCSI-2 card).  My FE book say
if I use a 501-1217-3 Channel adapter I should be ok?  Any Ideas?
