Q1: What provides termination inside the box? Is it on the motherboard
or is
one of the internal devices responsible?
A: A rough question. The simple answer is that it depends on the
controller.
Q2: The internal CD-ROM drive has the termination jumper closed
(enabled);
this seems strange since it is in the middle of a cable (it's on a cable
that goes from a connector on the motherboard to a connector on the
CD-ROM
back to a connector on the motherboard). Why would a device that's not
at
the end of cable be terminated? If this IS the correct place for a
terminator, what's terminating the high byte (the CD-ROM uses a 50-pin,
narrow SCSI connector)?
A: Presumably, the converter does the "right" thing.
Also, some of these drives uses the terminator by a jumper, so you might
see a terminator that's not being used because the jumper prevents it
from being used.
Q3: Are there any documents anywhere (on the web, preferably) that
describe
internal SCSI cabling and termination?
A: http://resource.simplenet.com/files/68_50_n.htm
General answers:
Can't answer your question but -- have you tried looking at docs.sun.com
or www.sunhelp.com?
-------------------
Though I don't think that they are, bear in mind that differential
UltraSCSI
requires no termination (just a really short cable length).
