failure, but it is the tester in this
case. Replace the Service
Processor to assure true failure
indication. If the failure disappears,
the Service Processor was bad.
Otherwise, reinstall the old Service
Processor.
2. Remove the CPU(s) and the
System Board. If the failure
returns, replace the I/O planar.
(See notes on 3-1.) Otherwise,
continue.
3. Install the System Board WITHOUT
the CPU(s). If the failure returns,
replace the System Board.
Otherwise, continue.
4. Install the CPU Card in slot 1. If
the failure returns, replace that
CPU Card. Otherwise, continue.
5. Install the CPU Card in slot 2 (if
there was one). If the failure
returns, replace that CPU Card.
Otherwise, continue.

problem was a bad connection,
and you have reseated the
possible connections.
