Diagnostic applications report problems by using service request numbers
(SRNs). The SRN identifies the component that detected the error code and
describes the error condition. Use the SRN information to identify a list
of possible failing items and to find information about any additional isolation
procedures.
Service request number formats
If your SRC is a 5-digit hexadecimal number or contains a hyphen in the
following formats (xxxxx, xxx-xxx, xxx-xxxx, xxxx-xxx, xxxx-xxxx), it is an
SRN.
Using the list of service request numbers
The list of SRNs is in numeric order. The SRNs in each range may include
codes that consist of anywhere from 6 to 8 digits. When the SRN you are looking
for contains 3 digits before the dash, select the link that contains the first
3 digits followed by the dash of that SRN. Use the same process when the SRN
you are looking for contains 4 digits before the dash. For example, if the
SRN is 2570-603, click SRNs 2502-101 through 25D0-108, because this SRN falls between
the number range of 2520-(x)xxx and 2590-(x)xxx.
The SRN tables use the following format:
The first column, Service Request Number (SRN), contains numbers that
represent specific failures of specific functions.
The second column, SRN Src. (SRN source code), contains the code that
identifies the program or procedure that produced the SRN. For more information
about using SRN Src codes, see SRN source code.
The third column, Failing Function Codes, represents functional areas
of the system unit. When available, the failing function code links to the
FRU that contains this function for each specific system unit.
The last column, Description and Action, offers a brief description of
the failure that this SRN represents. It also contains instructions for continuing
the problem analysis.
To use the list of SRNs, complete the following steps:
Click the item in the list of SRNs that includes the SRN that you want
to find.
When the SRN table appears, select the appropriate SRN from the first
column of the table.
Record the code letter for the Source of SRN (the SRN Src. column).
Record the failing function codes in the order listed.
Perform the action shown in the Description and Action column.
Note:
If your SRN is not listed, check to see if xxx or xxxx has been used. The
-xxx or -xxxx should always be the last SRN identified within a specific prefix.
For example, for SRN 950-xxxx, the xxxx represents the last entry within the
950 prefix.
SRN source code
When using SRNs to identify a problem and its resolution, you may need
to refer to the source code of the SRN. The SRN source code identifies the
program or procedure that produced the SRN. SRN source codes include the following:
A: The SRN is from a steady number in the control (operator) panel display.
B: The SRN is from a MAP (problem isolation procedure) callout.
C: The SRN was due to a missing resource at configuration time.
D: The SRN is from a diagnostic test after complete isolation testing.
E: The SRN is from a POST failure.
F: The SRN is from a diagnostic test after partial isolation testing.
G: The SRN is from the Error Log Analysis program.
H: The SRN is from a diagnostic message after an 888 sequence.
