RE: What to expect with a 9406-170?

Clay, do you have a piece of regular twinax cable available to you? I would
try that first.

You do not need a terminator on the splitter.

Hi Rob (and everybody),

Thanks for that link; I had found other documentation but not that
particular one yet.

I was able to get the console connected, and although I believe I did
the connection and configuration correctly, this is still my first time
working on this type of hardware. In any case, I still saw nothing on
screen but a cursor on the top right.

The 3476 is set to address 0
One side of the twinax splitter is plugged into port 0 on the 4-port
twinax brick (does the other side need a terminator?)
I used a balun on the splitter, connected to a cat-5 cable (tested,
works) to a balun on the 4-port twinax brick.

I'll be working on troubleshooting the failed device; please tell me
though if my console connection is incorrect.

I very much appreciate the assistance so far,
Clay Carley

A 675A error is part of the "I/O Processor and I/O Adapter Reference
Codes". That page says that the 3200 indicates "A tape/CD or disk device
reported a failure" and references these next steps: FI01105, STORIOA,
IOP, MEDIA. These, I believe, qualify as "Symbolic FRUs", (except for the
FI01105). But basically drilling around may have you go through Problem
Isolation Procedures (PIP) to determine the failing unit. For example
"SDIOP-PIP16" on page 311.
