A500 Server Initial booting H/W check error!!

[CA530285]

Hi!

I installed A500 Server a three weeks ago our clinet site.
At first, This Server work well no problem, but suddenly at processing booting occur falut.
After I power on the system, the system proceess selftest to check status of H/W(CPU,Memory,I/O etc).
while check the H/W status, booting has stop.
Then GSP mode enter.
The console display the error message.
A error message same as:
Source detail 9=serial
Source Id=0
problem detail:3
ALERT LEVEL:6=Boot Possible, Pending Failure,-action required.

Sometimes next message display.
processor unspecified 1000

So I doubt the main board, I replace the main board.
The result is same.
In this case, what parts replace the system?
what method the system find the error?
Personally, I doubt I/O board. correct or not?
As expert, Tell me your opinion.
thank you.

Hi,
If you are able to boot the machine.. check the ioscan and find out whether there are anything missing.. you can also use STM /usr/bin/stm and check for the log files.. you can do check for the specific component for any problems.

Hope this helps..

Thanks,
Anil
