Int-Pip14 Station Protectors; Int-Pip16 Licensed Internal Code; Int-Pip18 Ptfs Not Installed - IBM iSeries Series Hardware Problem Analysis And Isolation

v Peak load current is the steady state peak current of the iSeries system as determined by the
power profile.
For example, if the de-rating factor of the uninterruptable power supply is calculated to be 0.707,
then the uninterruptable power supply must not be used more than 70.7% of its kVA-rated capacity.
If the kVA rating of the uninterruptable power supply is 50 kVA, then the maximum allowable load
on it is 35.35 kVA (50 kVA multiplied by 0.707).
When a three-phase separately derived source is used, correct balancing of the load as specified in
step 6 (See page 112) is critical. If the load on any one phase of an uninterruptable power supply is
more than the load on the other phases, the voltage on all phases may be reduced.
15. If the system is attached to an uninterruptable power supply or motor generator, then check for the
following:
v The system and the attached equipment should be the only items that are attached to the
uninterruptable power supply or motor generator. Equipment such as air conditioners, copiers, and
FAX machines should not be attached to the same uninterruptable power supply, or motor
generator that the system is attached.
v The system unit console and the Electronic Customer Support modem must get ac voltage from
the same uninterruptable power supply or motor generator to which the system is attached.
This ends the procedure.
INT-PIP14 Station protectors: For use by authorized service providers.
Station protectors must be installed on all twinaxial cables that leave the building in which the iSeries
server is located. This applies even if the cables go underground, through a tunnel, through a covered
outside hallway, or through a skyway. Station protectors help prevent electrical noise on these cables from
affecting the iSeries server.
1. Look at the Product Activity Log to determine what workstations are associated with the failure.
2. Determine if station protectors are installed on the twinaxial cables to the failing workstations.
Are station protectors installed on the twinaxial cables to the failing workstations?
v Yes: Perform the next INT-PIP listed in the INT-PIP column.
This ends the procedure.
v No: You may need to install station protectors on the twinaxial cables to the failing workstations. See
chapter 9, section F in the iSeries Technical Information Manual, SY44-0008, for additional
information on station protectors.
This ends the procedure.
INT-PIP16 Licensed internal code: For use by authorized service providers.
Sometimes a dump of main storage is needed to analyze the problem. The data on the dump is analyzed
at the iSeries server factory to determine the cause of the problem and how to correct it.
1. Copy the main storage dump to tape. See Copying a Main Storage Dump in the iSeries Service
Functions book.
2. Ask your next level of support to determine if a Licensed Internal Code trouble report (LICTR) needs to
be written.
This ends the procedure.
INT-PIP18 PTFs not installed: For use by authorized service providers.
One or more PTFs may be available to correct this specific problem.
1. Ensure that all PTFs that relate to the problem have been installed.
Note: Ensure that the latest IOP PTF has been installed before you exchange an IOP card.
2. Ask your next level of support for more information.
This ends the procedure.
