It would be *much* more helpful (compared to your picture)
if you could be a bit more specific on its "deadness".
When you supply power:
Will the PSU fan still start?
Will it continue to run?
The Indigo CPU board has a yellow pilot light
visible from the front. Will it come up? Stay alight?
Do you still get the startup-chime from the speaker?
*Any* output on the screen? (I've kept a Indigo2
with a failed IMPACT graphics board in service simply
by disabling the (X11) graphics system - it still gave
fine console output.)
Most importantly: do you get better behaviour when you pull
components (cpu & gfx boards, disks; memory modules)?

I've heard, that I could analyze the system w/ a SGI-like serial line cable
on serial port #1? I don't hav' such a cable.
serial(7) has the pin assignments you need to solder an adapter.
This may seem silly advice considering your Indigo is dead but,
fortunately, SGI is still doing an outstanding job of providing
all kinds of information even on its legacy systems:
While you're at it, you might check out the "Indigo Owner's Manual".
IIRC it includes a trouble-shooting checklist.
Because my own Indigo R3K just died last weekend, I certainly feel with
you. Mine used to run 24/7 in our server room; I was logged in from
remote when it happened and would have got any serious syslog messages
(such as ECC memory faults) on my screen; there weren't any. A visit
next day showed a silent box, PSU fan not running anymore. The fan
will start when flipping the mains switch, but just for a single second.
Likewise, the CPU board's pilot light. Boards look OK (no burned parts,
no funny smells). No screen output whatsoever. Pulling boards/disks
doesn't improve PSU behaviour. Next step would be to sub-set modules.
I'd also like to pull the PSU to have it checked but so far it resisted
to come out.
The Ebay spare market is currently void of Indigo parts. (Indigo2 parts
can be seen quite often, but classic Indigos have always been a rarity.)
Good luck, Martin Neitzel
