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.
