4B2xxx43 Service Processor reports JTAG fail 1. Service Processor is the least likely
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.

System Board. If the failure
returns, replace the I/O planar.

the CPU(s). If the failure returns,
replace the System Board.

the failure returns, replace that
CPU Card. Otherwise, continue.
5. Install the CPU Card in slot 2 (if
