IBM xSeries 330 manual aPower supply bSystem board, Notes

4)Power-on system. If problem remains, suspect the following FRUs in the order listed:

a)Power supply

b)System board

If problem goes away, replace removed items one at a time until failing item is found (power-on and reconfigure system each time).

Notes:

1.If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the System Board.

2.If you suspect a networking problem and all the system tests pass, suspect a network cabling problem external to the system.
