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
Station protectors must be installed on all twinaxial cables that leave the building
in which the iSeries 400 system 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 400 system.
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?
No Yes
↓
Perform the next INT-PIP listed in the INT-PIP column.
This ends the procedure.
3. You may need to install station protectors on the twinaxial cables to the failing
workstations. See chapter 9, section F in the
iSeries 400 Technical Information
Manual , SY44-0008, for additional information on station protectors.
This ends the procedure.
INT-PIP16 Licensed Internal Code
Sometimes a dump of main storage is needed to analyze the problem. The data on
the dump is analyzed at the iSeries 400 system 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 information).
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
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.
INT-PIP20 Performance Problems
This procedure analyzes system performance problems.
1.
Look at the Product Activity Log and determine if any hardware errors
occurred at the same time that the performance problem occurred.
