caution

notice indicates the presence of a hazard that has the potential of causing

moderate or minor personal injury.

Electrical Safety

Observe the following safety instructions any time you are connecting or discon­necting devices attached to the workstation.

DANGER

An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the devices that attach to the
system. It is the responsibility of the customer to ensure that the outlet
is correctly wired and grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the power
cables for the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before
the signal cables are connected. If possible, disconnect all power
cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables
to prevent a possible shock from touching two surfaces with different
electrical potentials.

During an electrical storm, do not connect cables for display stations,
printers, telephones, or station protectors for communication lines.

Power Cables

To avoid electrical shock, a power cable with a grounded attachment plug is pro­vided. Use only properly grounded outlets.

Power cables used in the United States and Canada are listed by Underwriter's Lab­oratories (UL) and certified by the Canadian Standards Association (CSA). These
power cords consist of:

 Electrical cables, Type SVT or SJT.
 Attachment plugs complying with National Electrical Manufacturers Association

(NEMA) 5-15P. That is:

"For 230 V operation in the United States use a UL listed cable set consisting of a
minimum 18 AWG, Type SVT or SJT three-conductor cable a maximum of 15 feet in
length, and a tandem blade, grounding type attachment plug rated at 15 A, 250 V."

 Appliance couplers complying with International Electrotechnical Commission

(IEC) Standard 320, Sheet C13.

Power cables used in other countries consist of the following:

 Electrical cables, Type HD21.
 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 1-9

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 the safe operation of

the equipment.

 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.

12. Perform the following checks on each device that has its own power cables:

a. Check for damage to the power cord.

1-10

RS/6000 Enterprise Server Model H50 Installation and Service Guide

b. Check for the correct grounded power cable.
c. With the external power cable connected to the device, check for 0.1 ohm or

less resistance between the ground lug on the external power cable the
metal frame of the device.

13. Install the covers.

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 3-48.

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. Also check to ensure that
any client or server that addresses this system is updated.

the VPD module from the old Operator
Panel Control Assembly (connector U2) and
place in the new one.

2. I/O board (See notes on 2-1.)

The SMS configuration list or Boot sequence
selection menu shows more SCSI devices
attached to a controller/adapter than are actually
attached.

A device may be set to use the same SCSI bus
ID as the control adapter. Note the ID being
used by the controller/adapter (this can be
checked and/or changed via an SMS utility), and
verify that no device attached to the controller is
set to use that ID.

If settings do not appear to be in conflict:

1. Replace the SCSI cable.

2. Replace the device.

3. Replace the SCSI adapter (or I/O board if
connected to one of the two integrated SCSI
controllers on the I/O board). (See notes on
2-1 if the I/O board is replaced.)

Note: In a "Twin-tailed" configuration where

there is more than one initiator device
(normally another system) attached to

.

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.

Be prepared to record code numbers and use those numbers in the course of ana­lyzing a problem. Go to “Step 1020-1.”

2. Each power supply has a test switch. If you are instructed to replace a power
supply, see “Power Supply Test Switch Procedure” on page 7-18.

This procedure is used to locate power problems in system units. If a problem is
detected, this procedure helps you isolate the problem to a failing unit.

Observe the following safety notice during service procedures.

DANGER

An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the devices that attach to the
system. It is the responsibility of the customer to ensure that the outlet
is correctly wired and grounded to prevent and electrical shock.

Before installing or removing signal cables, ensure that the power
cables for the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before
the signal cables are connected. If possible, disconnect all power
cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables
to prevent a possible shock from touching two surfaces with different
electrical potentials.

During an electrical storm, do not connect cables for display stations,
printers, telephones, or station protectors for communication lines.

CAUTION:
This product is equipped with a three–wire power cable and plug for the user's
safety. Use this power cable with a properly grounded electrical outlet to avoid

Step 1520-11

Since the 7026-H50 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 7-19 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 5 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 Service
Processor, CPU, System Board or I/O board to avoid damage to them.

2. This MAP assumes that a CD-ROM drive is installed and connected to the inte­grated SCSI adapter, and a Diagnostics CD-ROM 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 can load.

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” on page A-13)

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.

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.

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.

Chapter 2. Maintenance Analysis Procedures 2-43

 The following table explains the meaning of the Power, Ready and Check status

LEDs.

Chapter 3. Error Code to FRU Index

The Error Code to FRU Index lists error 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.

If the codes in the following tables indicate a device which is present more than once
in the system unit, a location code is needed to specify which device generated the
error. Go to “Step 1020-4” on page 2-9 to display the System Management Services
error log and obtain a location code. Location code descriptions can be found under
“Location Codes” on page 3-48.

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 3-48.

2. Licensed programs frequently rely on network configuration, and system informa­tion stored on the VPD on the operator panel. If the MAPs indicate that the
Operator Panel 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. Also check to ensure that any
client or server that addresses this system is updated.

4. Each power supply has a test switch. If you are instructed to replace a power
supply, see “Power Supply Test Switch Procedure” on page 7-18.

If you replace FRUs and the problem is still not corrected, go to “MAP 1540:
Minimum Configuration” on page 2-25 unless otherwise indicated in the tables.

If you replace FRUs and the problem is corrected, go to "MAP 410: Repair

Error Code Description Action / Possible Failing FRU

20EE000A Pointer to the operating system found

in non-volatile storage.

Values normally found in non-volatile
storage that point to the location of an
Operating System were not found.
This can happen for two reasons,
either your installed Operating System
doesn't support storing the values or
some event occurred that caused the
system to lose non-volatile storage
information (drainage or replacement of
the battery). If you are running AIX,
this information can be reconstructed
by running the bootlist command speci­fying the device that the Operating
System is installed on. Please refer to
your AIX documentation for the exact
syntax and usage of the bootlist
command.

In order to boot the Operating System
so that the above mentioned values
can be reconstructed, power the
system down and power it back up
again, this should cause the system to
look for the Operating System in the
devices contained in the custom boot
list or in the default boot list, depending
on the condition of the system. If this
is not successful, modify the Boot
Sequence (also known as boot list) to
include devices that are known to
contain a copy of the Operating
System. This can be accomplished by
using the System Management Ser­vices Menus. For example, select a
hard disk known to have a copy of the
Operating System as the first and only
device in the boot sequence (boot list)
and attempt to boot again.

20EE000B The system was not able to find an

operating system on the device list that
was attempted.

Modify the Boot Sequence (also known
as boot list) to include devices that are
known to contain a copy of the Oper­ating System. This can be accom­plished by using the System
Management Services Menus. For
example, select a hard disk known to
have a copy of the Operating System
as the first and only device in the boot
sequence (boot list) and attempt to
boot again.
If the SMS menus do not display valid
SCSI devices which were previously
available:

1. Ensure SCSI signal and power
cables are securely connected and
not damaged.

2. Replace the I/O board.

21A000xxx SCSI Device Errors Notes:

1. Before replacing any system com­ponents:

a. Ensure that the controller and

each device on the SCSI bus is
assigned a unique SCSI ID.

b. Ensure SCSI bus is properly

terminated.

c. Ensure SCSI signal and power

cables are securely connected
and not damaged.

2. The location code information is
required to identify the ID of SCSI
device failures as well as to indi­cate the location of the controller to
which the device is attached.
