No sound.. do you have speakers plugged in?
Does the PSU 'CLICK' when you plug the kettle lead in? (Get your ear close).
If it's been transported by car or post, you may want to reseat everything. Your best bet.
Although yes.. it sounds like PSU gone to the great PSU pile along with a lot of my own. I doubt you will get anything from the serial, but it's worth a shot.
By no sound I meant there was no click from the psu, no fan whir, etc. sorry.
I also don't think the serial would do anything either as I don't hear anything at all from the machine.
Also, I reseated the cpu board and everything but there's no dice. I think the PSU is just borked. (how much am I expecting to pay for a replacement anyway..?)
From my limited experience with Octanes and SGI's in general, I can offer three scenario's I have come across that could help.
I know this is an asinine question, but when you reseated "everything" did that include the memory modules?
I was gifted an Octane main board with a CPU module that supposedly did not work. When I went to try it out in one my systems, I noticed the backplane never seated quite flush and I felt the locking mechanisms were not moving correctly. I found the screws holding the locking mechanisms to be quite loose. Tightening things up got it to seat better and work, no prob.
The PROM password reset jumper, if set in the position to reset the password, will leave the screen blank for roughly 10 minutes before displaying anything when you first power it on. The same board I got for free also had a PROM password set on it, so I got to experience reseting it first hand.
I like learning through observing other people, so this guy's video points out right where the jumper is on the main board:
If any of these do the trick, the lightbar on the front should turn red shortly after powering on and stay red until it's done performing the hardware tests.
I have certainly come across the failed power supply problem with just the relay 'click' and nothing else with two of my Octanes. I also tore apart the PSU, but don't see any smoking gun in the components. This is definitely a common failure of the Lucent PSU's.
