Checkpoints, error codes, and SRNs
The system uses various types of checkpoints, error codes, and SRNs, which are referred to throughout
this book (primarily in Chapter 4, "Checkpoints", on page 93, Chapter 5, "Error code to FRU index", on
page 125, Chapter 6, "Using the online and standalone diagnostics", on page 239, and Chapter 12, "Parts
information", on page 373). These codes can appear in the service processor boot progress log, the
operating system error log, and the operator panel. Understanding the definition and relationships of these
codes is important to the service personnel who are installing or maintaining the system.
Codes that can appear in the service processor boot progress log, the operating system error log, the
virtual terminal, and the operator panel are as follows:
Checkpoints
Checkpoints are displayed in the operator panel from the time AC power is connected to
the system until the operating system login prompt is displayed after a successful
operating system boot. These checkpoints have the following forms:
8xxx
9xxx
Exxx
0xxx
and
2xxx
Error Codes
If a fault is detected, an 8-digit error code is displayed in the operator panel. A location
code might be displayed at the same time on the second line.
SRNs
Service request numbers, in the form xxx-xxx, xxx-xxxx, xxxx-xxx, or xxxx-xxxx might also
be displayed on the operator panel and be noted in the AIX error log.
Use the following table to assist you in the identifying the types of error data that you might encounter:
Number of digits in error code
Any
4
5
6
8
Checkpoints can become error codes if the system fails to advance past the point at which the code is
presented. For a list of the checkpoints, see Chapter 4, "Checkpoints", on page 93. Each entry provides a
description of the event and the recommended action if the system fails to advance.

NAS Gateway 500 Service Guide
8xxx checkpoints are displayed from the time AC power is connected to the
system until the OK prompt is displayed by the service processor on the operator
panel. (Several 9xxx checkpoints are displayed just before the OK prompt is
displayed.)
9xxx checkpoints are displayed by the service processor after the power-on
sequence is initiated. A system processor takes control when 91FF is displayed on
the operator panel.
Note: Certain checkpoints might remain in the operator panel for long periods of
time. A spinning cursor is visible in the upper-right corner of the operator
panel during these periods to indicate that system activity is continuing.
Exxx checkpoints indicate that a system processor is in control and is initializing
the system resources. Control is being passed to the operating system when E105
is displayed on the operator panel. Location code information might also be
displayed on the operator panel during this time.
0xxx and 2xxx codes are operating system progress codes and configuration
codes. Location codes might also be shown on the operator panel during this time.
