Attachment plugs approved by the appropriate testing organization for the spe-
cific countries where they are used.
"For units set at 230 V (outside of U.S.): use a cable set consisting of a minimum 18
AWG cable and grounding type attachment plug rated 15 A, 250 V. The cable set
should have the appropriate safety approvals for the country in which the equipment
will be installed and should be marked HAR'."
Refer to Chapter 8 on page 8-1 to find the power cables that are available.
Chapter 1. Reference Information 1-15
Service Inspection Guide
Perform a service inspection on the system when:
The system is inspected for a maintenance agreement.
Service is requested and service has not recently been performed.
An alterations and attachments review is performed.
Changes have been made to the equipment that may affect its safe operation.
External devices with their own power cables have those cables attached.
If the inspection indicates an unacceptable safety condition, the condition must be
corrected before anyone can service the machine.
Note: The correction of any unsafe condition is the responsibility of the owner of the
system.
Perform the following checks:
1. Check the covers for sharp edges and for damage or alterations that expose the
internal parts of the system unit.
2. Check the covers for proper fit to the system unit. They should be in place and
secure.
3. Gently rock the system unit from side to side to determine if it is steady.
4. Set the power switch of the system unit to Off.
5. Remove the covers.
6. Check for alterations or attachments. If there are any, check for obvious safety
hazards such as broken wires, sharp edges, or broken insulation.
7. Check the internal cables for damage.
8. Check for dirt, water, and any other contamination within the system unit.
9. Check the voltage label on the back of the system unit to ensure that it matches
the voltage at the outlet.
10. Check the external power cable for damage.
11. With the external power cable connected to the system unit, check for 0.1 ohm
or less resistance between the ground lug on the external power cable plug and
the metal frame.
1-16
RS/6000 Enterprise Server Model H Series Installation and Service Guide
12. Perform the following checks on each device that has its own power cables:

Chapter 2. Maintenance Analysis Procedures (MAPs)
Entry MAP
Use the following table to determine your starting point.
Note: When possible, run Online Diagnostics in Service Mode. Online Diagnostics
perform additional functions, compared to Standalone Diagnostics. This ensures that
the error state of the system is captured in NVRAM for your use in fixing the
problem. The AIX error log and SMIT are only available when diagnostics are run
from the hard drive.
Notes:
1. If more than eight digits are displayed in the operator panel, use only the first
eight digits to find the error in the tables. The digits that display beyond the first
eight digits are location codes that can assist you in diagnosing the problem. See
“Location Codes” on page 3-68.
2. Licensed programs frequently rely on network configuration, and system information stored on the VPD on the operator panel control assembly (connector U2).
If the MAPs indicate that the Operator Panel Control Assembly should be
replaced, swap the VPD from the old operator panel to the new one. If the old
VPD module has to be replaced call technical support for recovery instructions.
If recovery is not possible, notify the system owner that new keys for licensed
programs may be required.
3. If a network adapter or the I/O board is replaced, the network administrator must
be notified so that the client IP addresses used by the server can be changed.
In addition, the operating system configuration of the network controller may
need to be changed in order to enable system startup. Ensure that all clients or
servers that address this system are updated.
Symptom Action

Purpose of This MAP
Use this MAP to get an error code if you were not provided one by the customer or
you are unable to load diagnostics. If you are able to load the diagnostics, go to
MAP 0020 in the Diagnostic Information for Multiple Bus Systems.
The Service Processor may have recorded one or more symptoms in its error log. It
is a good idea to examine that error log before proceeding (see Service Processor
System Information Menu).
The Service Processor may have been set by the user to monitor server operations
and to attempt recoveries. You may wish to disable these actions while you diagnose
and service the system. If you disable them, you should make notes of their current
settings for restoration before you leave. Following are the settings of your interest.
Surveillance From the Service Processor Setup Menu, go to
the Surveillance Setup Menu and disable surveillance.
Unattended Start From the Service Processor System Power
Control Menu, disable unattended start mode.
Reboot Policy From the System Power Control Menu, go to
the Reboot/Restart Policy Setup Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No
3. Enable supplemental restart policy to No.
Call Out From the Call-In/Call-Out Setup Menu, go to the
Serial Port Selection Menu and disable call-out
on both serial ports.
Be prepared to record code numbers and use those numbers in the course of analyzing a problem. Go to “Step 1020-1.”

MAP 1240: Memory Problem Resolution
Note:
The firmware checkpoint that sent you here could be one of the following:
E122, E213, E214, E218, E220 or E3xx
These checkpoints are referred to as "a memory checkpoint" in this MAP.
Purpose of this MAP
This MAP is used to trouble shoot a problem during the memory test when the
system stops at a memory checkpoint and no error code displays on the operator
panel.
Notes:
1. If the symptom changes while using this MAP, check for loose cards, cables, and
obvious problems. If you do not find a problem, go to “MAP 1540: Minimum
Configuration” on page 2-37.
2. The Service Processor may have recorded one or more symptoms in its error
log. It is a good idea to examine that error log before proceeding (see Service
Processor System Information Menu). Check the memory configuration in the
service processor menus. If a memory module has been deconfigured by the
system, swap the memory module positions on the memory card. The system
interprets this as an indication that the memory modules have been replaced. If
this does not work, perform the following steps:
Manually configure the memory module.
Reseat the memory card or module.
Re-ipl the system.
3. The Service Processor may have been set by the user to monitor server operations and to attempt recoveries. You may wish to disable these actions while
you diagnose and service the system. If you disable them, you should make
notes of their current settings for restoration before you leave. Following are the
settings of your interest.
Surveillance From the service Processor Setup Menu, go to the Surveillance Setup Menu
and disable surveillance.
Unattended
Start
From the Service Processor System Power Control Menu disable unattended
start mode.
2-10 RS/6000 Enterprise Server Model H Series Installation and Service Guide
Reboot Policy From the System Power Control Menu go to the Reboot/Restart Policy Setup
Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No
3. Enable supplemental restart policy to No.
Call-Out From the Call-In/Call-Out Setup Menu, go to the Serial Port Selection Menu and
disable call-out on both serial ports.
General Memory Information
Be sure to unplug the power cable before removing or installing the memory card(s)
or memory modules to avoid damage to them.
Memory cards can be installed in either slot (or both) on the system board, there is
no requirement that one be installed before the other.
It is perfectly acceptable for there to be two partially populated memory cards in the
system, the first memory card does not have to be fully populated before memory on
the second memory card is useable.
Memory modules, on the other hand, must be installed in matched (size and speed)
pairs. Refer to "Memory Card Locations" in chapter 1 for labeling of the memory card
and "Memory Cards" in Removal and Replacement Procedures for instructions on
module removal and installation. A single memory module pair may be installed in
module slots J1 and J2 (not slots J1 and J3). A second memory module pair could
be installed in module slots J5 and J6 (slots J3 and J4 do not have to be populated
first). Along these same lines, there is no requirement that memory module slots J1
and J2 be populated before another slot pair.
Step 1240-1
1. Ensure that the diagnostics and the operating system are shut down.
2. Turn the power off.

Step 1520-13
Since the H Series Enterprise Server can have redundant power supplies, it is not
necessary to power down the system in order to replace a power supply. The power
supplies are symmetrical so replacement starts with the left-hand unit (Power Supply
1). The exception to this rule is if the green LED on the back of one of the power
supplies is either blinking or not lit. In this case start with that power supply. See
“Power Supplies and Power Supply Fan Assemblies” on page 7-21 for instructions
on replacing a power supply. Before removing a power supply be sure the "other"
power supply is operational by observing the green LED, which should be lit. Also
be aware that the power supply exchange process must be completed within five
minutes, including moving the fan assembly from the removed supply to the replacement power supply. After five minutes, the Service Processor shuts the system
down to avoid overheating devices in the media and DASD bays.

MAP 1540: Minimum Configuration
Purpose of this MAP
This MAP is used to locate defective FRUs not found by normal diagnostics. For this
procedure, diagnostics are run on a minimally-configured system. If a failure is
detected on the minimally-configured system, the remaining FRUs are exchanged
one at a time until the failing FRU is identified. If a failure is not detected, FRUs are
added back until the failure occurs. The failure is then isolated to the failing FRU.
Notes:
1. Be sure to unplug the power cable before removing or installing the Service
Processor, processor card(s), memory card(s), System board or I/O board to
avoid damaging them.
2. This MAP assumes that a CD-ROM drive is installed and connected to the integrated SCSI adapter connector (port 1), and a Diagnostics CD-ROM disc is available.
3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM loads.
4. The term "POST indicators" refer to the icons (graphic display) or device mnemonics (ASCII terminal) that appear during the power-on self-test (POST).
5. The Service Processor may have recorded one or more symptoms in its error
log. It is a good idea to examine that error log before proceeding (see “System
Information Menu for Model H50” on page C-13 or “System Information Menu for
Model H70” on page C-15).
6. The Service Processor may have been set by the user to monitor server operations and to attempt recoveries. You may wish to disable these actions while
you diagnose and service the system. If you disable them, you should make
notes of their current settings for restoration before you leave. Following are the
settings of your interest.

SSA Maintenance Analysis Procedures (MAPs)
These maintenance analysis procedures (MAPs) describe how to analyze a continuous failure that has occurred in a system that contains two or more disk drive
modules. Failing field-replaceable units (FRUs) of the system unit can be isolated
with these MAPs.
How to Use These MAPs
Attention: Switching off the power to an SSA Hot-Swap Disk Drive can cause a
system fault unless you first make the SSA Hot-Swap Disk Drive modules unavailable to the system unit. To do this:
1. Use the system-management task menus to make the disk drive modules unavailable.
2. If the system unit has more than one SSA adapter, make the SSA Hot-Swap
Disk Drive modules unavailable to the system for each of the paths to the SSA
Hot-Swap Disk Drive.
Attention: Unless the system unit needs to be switched off for some other reason,
do not switch off the power to the system unit when servicing an SSA Hot-Swap Disk
Drive or the external SSA cable.
To isolate the FRUs associated with in the failing SSA Hot-Swap Disk Drive,
perform the actions and answer the questions given in this MAP.
When instructed to exchange two or more FRUs in sequence:
1. Exchange the first FRU in the list for a new one.
2. Verify that the problem is solved. For some problems, verification means
running the diagnostic programs (see the using-system service procedures).
3. If the problem remains:
a. Reinstall the original FRU.
b. Exchange the next FRU in the list for a new one.
4. Repeat steps 2 and 3 until either the problem is solved, or all the related
FRUs have been exchanged.
5. Perform the next action indicated by the MAP.
