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 manual and the
appropriate IBM PC/Netfinity Server Hardware
Maintenance Manual.
The following is a list of problems and references for
diagnosing the IBM Netfinity EXP15 Storage Expansion
Unit - Type 3520.
Problem Reference
Hard Disk Drive Numbering See “Drive Numbering”on
page 13.

Symptom-to-FRU Index for
the server that the Storage
Expansion Unit you are
servicing is connected to.

“Turning the Power On”
Performing a Shutdown
Note
If the Expansion Unit loses power unexpectedly, it
might be due to a hardware failure in the power
system or mid-plane (see “Symptom-to-FRU Index”on
page 7).
To perform a shutdown:
1. Make sure that all I/O activity has stopped. If
applicable, logically disconnect from the host
controller.
2. Make sure that all amber Fault LEDs are off. If any
Fault LEDs are lit (drives, power supplies, or fans),
correct the problem before you turn off the power.
3. Turn off both power supply switches on the back of
the expansion unit.
Turning the Power On
Use this procedure to power-on the Netfinity EXP15
Storage Expansion unit.
Initial start-up:
1. Verify that all communication and power cables
are plugged into the back of the expansion unit.
a. All hard disk drives are locked securely in
place.
b. The Option ID switch on the expansion unit
is set correctly.
c. The host controller and other SCSI bus
devices are ready for the initial power-up.
d. Power-on the expansion unit before
powering on the server.
2. Turn on the power to each device, based on this
power-up sequence.
3. Turn on both power supply switches on the back
of the expansion unit.
4. Only the green LEDs on the front and back
should be on. If one or more of the amber Fault
LEDs are on, refer to “Symptom-to-FRU Index”
on page 7.
Re-starting:
If you are re-starting after a normal shutdown, wait at
least ten seconds before you attempt to turn on either
power supply switch.

These levels are measured in controlled acoustical
environments according to ISO 7779 and are reported in
accordance with ISO 9296. The declared sound power
levels indicate an upper limit, below which a large portion
of machines operate. Sound pressure levels in your
location might exceed the average 1-meter values stated
because of room reflections and other nearby noise.
