Chapter 5. Error Code to FRU Index
Attention: Start your activity in this chapter by going to “Checkpoint and Error Code Index” on page 213.
In this section, you may be asked to perform additional isolation procedures before looking up the actions
for a 4-character checkpoint or 8-character error code.
The Error Code to FRU Index lists fault symptoms and possible causes. The most likely cause is listed
first. Use this index to help you decide which FRUs to replace when servicing the system.
v If you replace FRUs or perform an action and the problem is still not corrected, go to “MAP 1548:
Processor Subsystem Problem Isolation” on page 139 unless otherwise indicated in the tables.

If you replace FRUs and the problem is corrected, go to

Note: Do not shut down the system if the FRU was replaced by hot swap.
Performing Slow Boot
On this system, the error code displayed in the operator panel or in the service action event (SAE) log
may not indicate the root cause of the problem. To fully analyze all of the available information, perform
the following steps before doing a hardware repair or replacement:
1. Record the 8-character error code (and location code if present) in operator panel.
2. Do a slow-mode boot into the SMS main menu. (A fast-mode boot skips much of the built-in diagnostic
testing.) A slow-mode boot may yield a new 8-character error code on the operator panel or new errors
in the service processor error log. If a new error code is reported, record it for use in subsequent
steps. Slow mode boot is selected through the service processor menus. The procedure is different for
systems without an HMC attached versus systems with an HMC attached.
v
Systems without an HMC attached:
a. Go to the system power control menu from the service processor main menu.
b. Select option 7, the boot mode menu.
c. On the boot mode menu, select option 1. This automatically enables Boot to SMS menus.
d. Enter 98 to go back to the system power control menu.
e. Look at the state of the fast boot enable, option 6. If it is enabled, select option 6 to change it to
disabled (disabling fast system boot automatically enables slow mode boot).
If it is already disabled, it may have been disabled by the service processor because the
previous boot failed.
In either case, boot the system by continuing to substep 2f.
f. Select option 4 to power on the system. Enter y when prompted. The system will power up and
begin the boot process.
g. When the system stops at the SMS main menu, use the white power button on the operator
panel to power down the system.
At this point, the service processor menus should be available to examine the service processor
error logs.
v Systems with an HMC attached:
a. From the HMC, select Partition Manager .
b. Highlight the processor subsystem name.
c. Right-click the mouse and select Open Terminal Window .
d. From the Service Processor Menu on the VTERM select Option 2 System Power Control
Menu .
