Appendix B. Preventive Maintenance (Pm) Checklist - IBM Application System/400 Service Information

Appendix B. Preventive Maintenance (PM) Checklist
All items in the following list should be completed
during every preventive maintenance call.
1. Perform control panel lamp test (function
04).
2. Review the PTF level:
PTFs correct problems that look like hard-
ware failures. Discuss with the customer
the importance of installing PTFs on a
regular basis to decrease possible down
time. Show the following procedure to any
new system operator.
a. Determine the last cumulative PTF
package that was installed. Enter
DSPPTF 5738SS1 (the Display PTF
command) to display the cumulative
PTF package level. For example,
TC94012 as the first entry indicates
the date of the latest PTF package
installed (the 94 in the entry indicates
1994; the 012 indicates the 12th day
of the year).
b. Recommend that the customer install
the latest cumulative PTF package if
three months have passed since a
cumulative PTF package has been
installed. If the customer does not
install the entire cumulative PTF
package, recommend that at least the
High Impact and Pervasive (HIPER)
PTFs on the latest cumulative PTF
package be installed. The instructions
that come with the cumulative PTF
package can be used to load HIPER
PTFs.
Do the following to order the latest
cumulative PTF package. (Cumulative
PTF packages are available to all
basic license holders).
1) Enter SNDPTFORD SF99vrm
(vrm=300 for Version 3 Release
0.5 Modification 0).
2) Enter SNDPTFORD SF98vrm to
obtain the Preventive Service
Planning (PSP) information about
the PTF package.
Note: You can also use GO
CMDPTF (the Go command) for a
menu to order a PTF package.

3. Perform the Control Panel Battery Check.
Use WRKPRB (the Work with Problem
command) and check for error entries indi-
cating the control panel battery is low.
4. Review the Error Log for possible prob-
lems (see "Error Log Utility" under "System
Service Tools" in the Service Functions
User's Guide).
Note: If the Error Log is wrapping too fre-
quently, increase the Error Log sizes to
the recommended values under the Error
Log utility using STRSST.
5. Inspect the system for safety hazards
(loose cables, open doors, bent covers).
6. Inspect the site environment where the
system is kept.
Make recommendations to the customer
for items that do not meet IBM specifica-
tions. These items include:
The system is in a limited area
Poor ventilation
Blocked air vents
The environment is hot
The environment has dust
7. Use the 1/0 device service information to
determine and perform 1/0 device preven-
tive maintenance.
8. Vacuum if necessary.
9. Clean all system and 1/0 covers.
_ 10. Record any action in the Service Log in
the Account Management Planning Guide
or in Appendix E, "Service Log" on
page E-1.

to the one on the label of the Model-
Unique Licensed Internal Code (MULlC)

found on the system (hardware, software,
performance).
