RE: 170 Dropping Hard

We had the exact same problem with our 170 and it did turn out to be the PS.
It would stay up for 20 minutes or so and then just shut itself off, no
warning, nothing.....also check the lower fan in the front of the chassis
and make sure it is still working....ours had quit and that contributed to
the overheating problem.  It is a small chassis fan that sits at the bottom
of the chassis in front......cheap to replace, but it it is not operating
you could be seeing a higher temp than the 170 likes.....\

The powerware UPS also might have a bogus card - gives wrong signal - i
forget the details and which model. I think that is what elvis is talking
about - i was at centerfield at the time

We've had this happen once where UPS had serial connection to talk 
back to the iSeries and UPS was misinterpreting power levels and 
signaling iSeries to power itself down.
Took us a little while to figure it out :)

We have a 170 running V5R2 for our development and in the past 4 years 
it has dropped 6 times (3 times in the past week). In all cases there 
were no messages in the logs on any hardware failures. Our tech 
suggested we replace the power supply, which we did the first 3 times.
Now we are having a hard time coming up with other possibilities. We 
don't believe that the power supply is an issue and we have the system 
on a ups which our 810 is running on the same ups and it does not go 
down.

Has anyone seen this before or know of anything else we can check? 

Thanks,

Curt VanCalster
