Chapter 4. Problem DeterminationProcedures
This chapter contains step-by-step instructions that can help you
determine if your PCI co-processor adapter is operating properly in
an Intel-based, IBM-compatible system. See “Step 2. Download the
Diagnostics and Operating System Support Programs” on page 2-5
for information on downloading diagnostics for other supported
system unit hardware platforms.
Note: To test the PCI co-processor adapter after completing the
initial installation of it, see “PCI Co-Processor Adapter
Diagnostics Test” on page 4-3.
The contents of the chapter are:
System unit diagnostics (page 4-2)
PCI co-processor adapter diagnostics (starting on page 4-3)
Service parts (starting on page 4-22).
If you suspect you have a problem:
Check electrical connections (that is, cable connections between
devices, cable connections between devices and wall outlets,
and wall outlet condition).
Perform diagnostics.
Two groups of tests can be performed when there is a problem with
a system unit containing the PCI co-processor adapter.
1. System Unit Diagnostics. These tests are run from a diagnostics
diskette provided with the system unit; they examine the system
unit and the installed options.
2. PCI Co-Processor Adapter Advanced Diagnostics Version 1.50.
These tests are run from the

IBM Realtime Interface

Co-Processor: Advanced Diagnostic

diskette; they examine the
PCI co-processor adapter.
