Hello Netland, this is a SCSI termination question :

I know of two very different ways of terminating SCSI cables; one is with
terminator plugs, and the other is with device on-board terminators.

This disk I have here, for a Sun, says that some Sun SCSI busses do not
provide termination power on the SCSI bus, and termination must therefore
be done by on-board terminators, with the disk supplying termination
power.

I much prefer using SCSI termination plugs to openning the box up every
time I want to reconfig something...

Now for the question(s) :

- Which Suns don't provide termination power on the SCSI bus ?
  (Does the Sparcstation 1,1+,SLC,IPC ?)

- If the Sun DOES provide termination power, can setting the terminators
  on the drive to use the drive's power HURT anything (two power sources) ?

AdvThanks,

Gil.
