Diagnostics and Test Information
Important
The service procedures are designed to help you
isolate problems. They are written with the
assumption that you have model-specific training on
all computers, or that you are familiar with the
computers, functions, terminology, and service-related
information provided in this supplement and the PC
Servers Hardware Maintenance Manual (part number
70H0751, form number S30H-2501-01).
The following is a list of problems and references for
diagnosing the PC Server Rack Storage Enclosure - Type
3519.
Problem Reference
Error Codes/Error Messages Refer to the
Symptom-to-FRU Index for
the server that the Storage
Enclosure you are servicing
is connected to.
Fan Light indications See “Controls and
Indicators” on page 14 and
“Symptom-to-FRU Index” on
page 24.
Hot Swap Tray LED
indications
See “Hot-Swap Drive Tray
III” on page 19.
Power Supply Voltages See “Power Supply (FRU
Number 60H8301)” on
page 4.
Setting SCSI IDs See “SCSI IDs” on page 6.
Terminating a SCSI chain See “SCSI Termination” on
page 10.
Power-on Self-Test
When you power-on the server, it performs a series of
tests to check the operation of the system, including the
drives and other components of the storage enclosure.
This series of tests is called the
power-on self-test
, or
POST
. If the tests indicate a problem, a message appears
on the server's information panel or display.
Rack Storage Enclosure - Type 3519 3
Power-on Sequence
Note
For normal operation, power on the server; then,
power on the expansion enclosure.
The expansion enclosure can be powered on without
connecting it to a server. However, the expansion
enclosure must be connected to a server before the drives
installed in the enclosure can be used.
Power Supply (FRU Number 60H8301)
Note
Verify that the voltage-select switch is set for the
correct voltage. If the voltage switch is set to the
wrong position, permanent damage might occur to the
rack when you power it on.
If the power-on indicator is not on, and the power-supply
fan is not running, check the power cord for proper
installation and continuity.
If the power cord is OK, either the power supply is
defective or a defective device is causing the power supply
to shut off. Check the power supply voltages.
The power supply is rated at 200 watts. Too many
devices (adapters or hard disk drives) can cause power
consumption to exceed 200 watts and cause the power
supply to shut down. See “Power Supply Shutdowns” on
page 5. Remove adapters or devices to determine if this
is the cause.
If the voltages are incorrect, replace the power supply.

Power Supply Shutdowns:
If the power supply shuts down, or
appears
to fail at
power-on, you might have one of the following problems:
Too many devices are set to start instantly. See
“Setting the Motor-Start Jumper” on page 414 in the
PS/2 Hardware Maintenance Manual.
There are too many large-capacity devices installed
(such as hard disk drives). The nominal operating
current of the devices installed collectively exceeds
the available current of the power supply. See the
“Personal System/2 Installation Planning” guide (form
number S41G-2927) for more information.
Also ensure that the fans operate when the machine is
powered on.
Note
Verify that the voltage-select switch (if applicable) is
set for the correct voltage.

Rack Storage Enclosure - Type 3519 5
SCSI IDs: Each SCSI device installed in the storage
enclosure must have a unique SCSI identifier (ID). This
unique ID enables the SCSI controller to recognize the
device. This SCSI ID also prevents two devices from
attempting to send or receive data on the SCSI bus at the
same time. IBM PC Server SCSI controllers use ID 7.
Therefore, you must not assign ID 7 to any device that you
install in the storage enclosure. SCSI devices support the
following IDs:
Narrow devices support SCSI IDs 0 to 6.
Wide devices support 0 to 6 or 8 to 15.
When you install a hot-swap drive, the backplane behind
bays 4 through 9 automatically assigns the drive its SCSI
ID. However, when you install a drive in bays 1 through 3,
you must set a unique SCSI ID for the drive that does not
conflict with any of the IDs that the backplane assigns to
drives in bays 4 through 9.
Depending on the setting of the SCSI ID address jumper
(J12) on the rear of the backplane, the backplane sets the
SCSI IDs for bays 4 through 9. SCSI IDs 8 to 13 are the
default IDs for the hot-swap drives. SCSI IDs 0 to 5 are
also available for the hot-swap drives.
The SCSI ID address jumper, a pin block with four pairs of
pins (J12), is located on the rear of the backplane. The
default, cover installed on the HI ID N pins, sets the
addresses to HI.
J12
The backplane sets the SCSI IDs for bays 4 through 9 as
follows:
LO Settings HI Settings (default)
Bay SCSI ID
4 0
5 1
6 2

The following table summarizes the jumper settings for the
SCSI ID address jumper (J12).
Refer to the documentation that came with the drive for
information about setting its SCSI ID.
If the storage enclosure is attached to a RAID adapter,
refer to the information that came with the adapter for
SCSI ID requirements.

Sets SCSI IDs to HI. Use
this setting, cover installed
on the HI ID N pins, when
you install narrow
non-hot-swap devices and
the configuration requires
you to define some
non-hot-swap devices with
high IDs. This is the default
setting.
SCSI Repeater Cards
Note
If you connect the storage enclosure to a
non-disk-array server, the SCSI bus must be
dedicated to the storage enclosure. That is, you
cannot connect other devices to the SCSI bus.
The storage enclosure comes equipped to connect to one
server. To connect:
Two servers and one storage enclosure, see
“Connecting Two Servers and One Storage
Enclosure” on page 8.
One server and two storage enclosures, see
“Connecting One Server and Two Storage
Enclosures” on page 9.
Rack Storage Enclosure - Type 3519

Connecting Two Servers and One Storage
Enclosure: To install a second SCSI Repeater Card
to connect two servers and the storage enclosure, do the
following.
1. Set the SCSI ID address jumper on the backplane of
the storage enclosure to HI. See “SCSI IDs” on
page 6 for information on the SCSI ID address
jumper.
2. Assign a unique SCSI ID to the SCSI controller of
each server. For example, if the SCSI controller in
both servers is set to 7, set the SCSI ID of one SCSI
controller to 6.
3. Install the SCSI Repeater Card in the expansion
enclosure.
4. Connect the power cable to the SCSI Repeater Card.
5. Connect one end of the SCSI option cable to the
internal SCSI connector on the SCSI Repeater Card;
then, connect the other end of the cable to the
backplane on the storage enclosure.

Note
You must have a Y-cable available for connecting the
server and storage enclosures. The Y-cable can be
ordered from an IBM marketing representative or an
IBM reseller.
To connect the storage enclosure to one server and
another storage enclosure, do the following.
1. Set jumpers (J3 and J6) on the SCSI Repeater Card.
J3
J6
The default settings for both jumpers is ON (covers
on each jumper). The following table summarizes the
jumper settings for the SCSI Repeater Card jumpers.
Jumper Description
J3 Leave the jumper in the ON
position.
J6 Use the OFF position (cover
removed) to connect the
storage enclosure to the
double connector of a
Y-cable.
Use the ON position (cover in
place) in all other cases.

SCSI Termination
Termination ensures that the quality of the signal is
maintained throughout the SCSI chain. If you chain SCSI
devices in bays 1 through 3, the backplane automatically
sets termination for all devices. The backplane also
automatically sets termination for hot-swap drives.
Before you install a SCSI device, set the termination to
DISABLED. On some devices, you will need to remove
jumpers. Refer to the information that came with the
device for instructions.

Safety Information
The following section contains the safety information that
you need to be familiar with before servicing an IBM
computer.
General Safety
Follow these rules to ensure general safety:
Observe good housekeeping in the area of the
machines during and after maintenance.
When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally
between your feet.
3. Use a slow lifting force. Never move suddenly
or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg
muscles; this action removes the strain from the
muscles in your back.
Do not attempt to lift any
objects that weigh more than 16 kg (35 lb) or
objects that you think are too heavy for you.
Do not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
Before you start the machine, ensure that other
service representatives and the customer's personnel
are not in a hazardous position.
Place removed covers and other parts in a safe
place, away from all personnel, while you are
servicing the machine.
Keep your tool case away from walk areas so that
other people will not trip over it.
Do not wear loose clothing that can be trapped in the
moving parts of a machine. Ensure that your sleeves
are fastened or rolled up above your elbows. If your
hair is long, fasten it.
Insert the ends of your necktie or scarf inside clothing
or fasten it with a nonconductive clip, approximately 8
centimeters (3 inches) from the end.
Do not wear jewelry, chains, metal-frame eyeglasses,
or metal fasteners for your clothing.
Remember: Metal objects are good electrical
conductors.
Wear safety glasses when you are: hammering,
drilling soldering, cutting wire, attaching springs, using
solvents, or working in any other conditions that might
be hazardous to your eyes.
After service, reinstall all safety shields, guards,
labels, and ground wires. Replace any safety device
that is worn or defective.
Reinstall all covers correctly before returning the
machine to the customer.

Electrical Safety
Observe the following rules when working on electrical
equipment.
Important
Use only approved tools and test equipment. Some
hand tools have handles covered with a soft material
that does not insulate you when working with live
electrical currents.
Many customers have, near their equipment, rubber
floor mats that contain small conductive fibers to
decrease electrostatic discharges. Do not use this
type of mat to protect yourself from electrical shock.
Find the room emergency power-off (EPO) switch,
disconnecting switch, or electrical outlet. If an
electrical accident occurs, you can then operate the
switch or unplug the power cord quickly.
Do not work alone under hazardous conditions or
near equipment that has hazardous voltages.
Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
Before you start to work on the machine, unplug the
power cord. If you cannot unplug it, ask the customer
to power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
If you need to work on a machine that has
exposed
electrical circuits, observe the following precautions:
– Ensure that another person, familiar with the
power-off controls, is near you.
Remember: Another person must be there to
switch off the power, if necessary.
– Use only one hand when working with
powered-on electrical equipment; keep the other
hand in your pocket or behind your back.
Remember: There must be a complete circuit to
cause electrical shock. By observing the above
rule, you may prevent a current from passing
through your body.
– When using testers, set the controls correctly
and use the approved probe leads and
accessories for that tester.
– Stand on suitable rubber mats (obtained locally,
if necessary) to insulate you from grounds such
as metal floor strips and machine frames.
Observe the special safety precautions when you
work with very high voltages; these instructions are in
Related Service Information
31
the safety sections of maintenance information. Use
extreme care when measuring high voltages.
Regularly inspect and maintain your electrical hand
tools for safe operational condition.
Do not use worn or broken tools and testers.
Never assume
that power has been disconnected
from a circuit. First,
check
that it has been
powered-off.
Always look carefully for possible hazards in your
work area. Examples of these hazards are moist
floors, nongrounded power extension cables, power
surges, and missing safety grounds.
Do not touch live electrical circuits with the reflective
surface of a plastic dental mirror. The surface is
conductive; such touching can cause personal injury
and machine damage.
Do not service the following parts
with the power on
when they are removed from their normal operating
places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct
grounding of the units.)
If an electrical accident occurs:
– Use caution; do not become a victim
yourself.
– Switch off power.
– Send another person to get medical aid.
Safety Inspection Guide
The intent of this inspection guide is to assist you in
identifying potentially unsafe conditions on these products.
Each machine, as it was designed and built, had required
safety items installed to protect users and service
personnel from injury. This guide addresses only those
items. However, good judgment should be used to identify
potential safety hazards due to attachment of non-IBM
features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine
how serious the apparent hazard could be and whether
you can continue without first correcting the problem.
Consider these conditions and the safety hazards they
present:
Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal
electrical shock).
Explosive hazards, such as a damaged CRT face or
bulging capacitor
32 PC Server HMM
Mechanical hazards, such as loose or missing
hardware
The guide consists of a series of steps presented in a
checklist. Begin the checks with the power off, and the
power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or
sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition.
Use a meter to measure third-wire ground
continuity for 0.1 ohm or less between the
external ground pin and frame ground.
b. The power cord should be the appropriate type
as specified in the parts listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use
good judgment as to the safety of any non-IBM
alterations.
6. Check inside the unit for any obvious unsafe
conditions, such as metal filings, contamination, water
or other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws
or rivets) have not been removed or tampered with.

Handling Electrostatic
Discharge-Sensitive Devices
Any computer part containing transistors or integrated
circuits (ICs) should be considered sensitive to electrostatic
discharge (ESD). ESD damage can occur when there is a
difference in charge between objects. Protect against ESD
damage by equalizing the charge so that the machine, the
part, the work mat, and the person handling the part are all
at the same charge.
Notes:
1. Use product-specific ESD procedures when they
exceed the requirements noted here.
2. Make sure that the ESD protective devices you use
have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
Keep the parts in protective packages until they are
inserted into the product.
Avoid contact with other people.
Wear a grounded wrist strap against your skin to
eliminate static on your body.
Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
Use the black side of a grounded work mat to provide
a static-free work surface. The mat is especially
useful when handling ESD-sensitive devices.
Select a grounding system, such as those listed
below, to provide protection that meets the specific
service requirement.
Note: The use of a grounding system is desirable
but not required to protect against ESD
damage.
– Attach the ESD ground clip to any frame ground,
ground braid, or green-wire ground.
– Use an ESD common ground or reference point
when working on a double-insulated or
battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the AC plug on
AC-operated computers.
Grounding Requirements
Electrical grounding of the computer is required for
operator safety and correct system function. Proper
grounding of the electrical outlet can be verified by a
certified electrician.

Problem Determination Tips
Due to the variety of hardware and software combinations
that can be encountered, use the following information to
assist you in problem determination. If possible, have this
information available when requesting assistance from
Service Support and Engineering functions.
Machine type and model
Processor or hard disk upgrades
Failure symptom
– Do diagnostics fail?
– What, when, where, single, or multiple systems?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made
prior to it failing?
– Is this the original reported failure?
Reference/Diagnostics Diskette Version
– Type and version level
Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
Operating system software
– Type and version level
Important
To eliminate confusion, identical systems are
considered
identical
only if they:
1. Are the exact machine type and models
2. Have the same BIOS level
3. Have the same adapters/attachments in the
same locations
4. Have the same address
jumpers/terminators/cabling
5. Have the same software versions and levels
6. Have the same Reference/Diagnostics Diskette
(version)
7. Have the same configuration options set in the
system
8. Have the same setup for the operation system
control files
Comparing the configuration and software set-up
between “working and non-working” systems will often
lead to problem resolution.
