Just FYI, the dust inside the power supply probably contributed to its early demise.  It is a good idea to get a couple of cans of
compressed air and clean out the fans and power supplies every once in a while.  That goes for PCs, desktops, servers, your TV at
home and other electronic equipment.  The current is a magnet for dust bunnies and other such putrid creatures.

 Thank You for the reply.....  I don't know what model number the SCSI
is but your post (Tom) gave me the courage to open the box and the
design is pretty straight forward.  It appears to be the power supply.
As I recall now, the cooling fan that is built into the supply was
making noise last week.  I will shop around for a replacement.  I
can't believe the amount of dust inside!!
Thanks
