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

8 4

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 7

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.

Connecting One Server and Two Storage
Enclosures
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.

2. Set the SCSI ID address jumpers on the backplanes
of the storage enclosures. See “SCSI IDs” on page 6
for information on the SCSI ID address jumpers. The

requirements.

The storage enclosures can contain a maximum of

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.
