Power PIP3: For use by authorized service providers.
Use this procedure to isolate a failure in the system power. You will be testing the battery power unit for
correct operation. Read the “Power PIPs” on page 152 for important safety information before servicing the
system.
Attention: Disconnecting or removing the 2620 or 2628 cryptographic I/O processor causes the loss of the
master encryption key.
1. If the system has logical partitions, perform this procedure only from the Primary partition’s console
and the system control panel. To determine if the system has logical partitions, go to Determine if the
system has logical partitions, before continuing with this procedure.
2. Ensure that the battery power unit is installed and that there was no system power loss for the last
eight hours by checking the message log for CPF1816. If the message log shows that a power loss
occurred in the last 8 hours, the battery may not be at full charge and the test may fail. To check the
message log, perform the following:
a. Enter the command DSPLOG QHST
b. Press F4 (prompt).
c. Fill in the time and date. (The time date parameter that you use should be for the last 8-hour
period.) For the United States, the format is hhmmss mmddyy.
Note: The output may be printed (*PRINT) or displayed. The default (*) is to display.
3. Ensure that all user programs are ended.
4. Perform the following:
a. Ensure the keystick is inserted and select Manual mode on the control panel.
b. Select function 21 (Make DST Available) on the control panel.
c. Press Enter.
d. Enter the password on the DST Sign On display. You need the customer password to get to the
Use Dedicated Service Tools (DST) display.
5.
Select Start a Service Tool —> Hardware service manager —> System Power Control Network
—> and press Enter.
6. Select Test Battery Interface by entering 7 under the OPT column on the line for the correct unit (not
the line for the frame).
7. Press Enter to confirm your selection.
Does the battery test complete with no problems found?
v Yes: Approximately 24 hours from now, the system will perform a battery capacity test. When the
battery capacity test completes successfully, the battery power unit test is complete.
This
ends the procedure.
v No: Exchange the following, one at a time. See the Remove and replace procedures or the remove
and replace procedures in the Migrated Expansion Tower Problem Analysis, Repair and Parts
manual on the V5R1 Supplemental Manuals web site
.
a. Battery power unit (see symbolic FRU “BATRY” on page 285).
b. Battery charger unit (see symbolic FRU “BATCHGR” on page 285) or uninterruptible power
supply (see symbolic FRU “UPSUNIT” on page 476), as installed.
c. The SPCN card (see symbolic FRU “TWRCARD” on page 470).
d. Backplane (see symbolic FRU “BACKPLN” on page 284).
This ends the procedure.
