d. On the Select Timeframe display, change the From: Date and Time to a date and time prior to
when the customer reported having the problem.
e. Find an entry that matches one or more conditions of the problem:
1) SRC
2) Resource
3) Time
4) FRU list (choose Display the failing item information to display the FRU list).
Notes:
a. All entries in the service action log represent problems that require a service action. It may be
necessary to handle any problem in the log even if it does not match the original problem
symptom.
b. The information displayed in the date and time fields are the time and date for the first occurrence
of the specific system reference code (SRC) for the resource displayed during the time range
selected.
Did you find an entry in the Service Action Log?
v No: Continue with the next step.
v Yes: Go to step 9 (See page 22).
8. DANGER
To prevent the system from powering on automatically during service procedures, select Manual or Secure
mode on the system unit control panel. (RSFTD214)
Exchange the following parts one at a time (see Remove and replace procedures). After exchanging
each part, go to step 5 (See page 21) to verify that the system can perform an IPL at a specified time.
Note: If you exchange the control panel or the SYSBKPL, you must set the correct date and time by
performing step 4 (See page 20).
Attention: Before exchanging any part, power off the system (see Power on/off the system and logical
partitions).
v SYSBKPL
v System control panel
v System control panel cable
Did the IPL complete successfully after you exchanged all of the parts listed above?
v No: Contact your next level of support.
This ends the procedure.
v Yes: Continue with the next step.
9. Was the entry isolated (is there a Y in the Isolated column)?
v No: Go to System Reference Codes and use the SRC indicated in the log.
This ends the procedure.
v Yes: Display the failing item information for the Service Action Log entry. Items at the top of the
failing item list are more likely to fix the problem than items at the bottom of the list.
Exchange the failing items one at a time until the problem is repaired. After exchanging each one of
the items, verify that the item exchanged repaired the problem.
Notes:
a. For failing items (see "Failing items" on page 249), and symbolic FRUs (see Symbolic FRUs).
b. When exchanging FRUs, go to Remove and replace procedures. If you are exchanging a disk
unit, go to Recovery procedures.
c. After exchanging an item, go to Verify the repair.
