Chapter 5. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the server.
If you cannot diagnose and correct a problem by using the information in this
chapter, see Appendix A, “Getting help and technical assistance,” on page 121 for
more information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v
POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST” for more
information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 96.
v Server LEDs
Use the LEDs on the server to diagnose system errors quickly. See “Error LEDs”
on page 106 for more information.
v
Diagnostic programs and messages The Dynamic System Analysis (DSA)
diagnostic programs are the primary method of testing the major components of
the server. The DSA diagnostic programs are available on the IBM
Dynamic
System Analysis Preboot Diagnostic CD that is shipped with the Lotus
Foundations Appliance and is also available online. To obtain the DSA program
online:
1. Go the following IBM Web page:

2. From the Product family drop-down box, select Lotus Foundations Appliance
3. From the Operating systems drop-down box, select All listed operating
systems , then click Go .
4. The screen will refresh with additional search options. From the Refine
results drop-down box, select Diagnostics and click Go .
5. Download the DSA .iso image and burn it to a CD. Also be sure to download
and read the available readme.txt file for detailed instructions on how to use
the DSA program.
Attention: Because the Lotus Foundations Appliance does not ship with a
CD/DVD drive, you will need to connect a removable USB CD/DVD drive to the
back of the unit in order to use the DSA program.
POST
When you turn on the server, it performs a series of tests to check the operation of
the server components and some optional devices in the server. This series of tests
is called the power-on self-test, or POST.
