IBM X.25 manual Problem Determination, Chapter

Chapter 4.	Problem Determination
Procedures
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:
Ÿ	System unit diagnostics (page 4-2)
Ÿ	PCI co-processor adapter diagnostics (starting on page 4-3)

ŸService parts (starting on page 4-22).

If you suspect you have a problem:

ŸCheck electrical connections (that is, cable connections between

devices,	cable connections between devices and wall outlets,
and wall	outlet condition).

ŸPerform 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 IBMfrom Realtimethe Interface Co-Processor: Advanced Diagnosticdiskette; they examine the PCI co-processor adapter.
