Using the list of service request numbers

This section describes how to use the list of service request numbers (SRN).

About this task

The list of SRNs is in numeric order. The SRNs in each range might 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 2520-101 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 source 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.
  • 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. The SRN list is common with other products using the same underlying operating system and so in some cases the recommended actions might not be possible on the 2107. If this is the case then just follow the link to the referenced MAP and continue with the problem analysis from there.

To use the list of SRNs, complete the following steps:

Procedure

  1. Click the item in the list of SRNs that includes the SRN that you want to find.
  2. When the SRN table appears, select the appropriate SRN from the first column of the table.
  3. Record the code letter for the Source of SRN (the SRN source column).
  4. Record the failing function codes in the order listed.
  5. 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.
