Electrical Safety

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

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 communications lines.

D05

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
electrical shock.

C01

Laser Safety Information

CAUTION:
This product may contain a CD-ROM, DVD-ROM, or laser module on a PCI card,
which are class 1 laser products.

C30

Laser Compliance

All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR
Subchapter J for class 1 laser products. Outside the U.S., they are certified to be in
compliance with the IEC 825 (first edition 1984) as a class 1 laser product. Consult the
label on each part for laser certification numbers and approval information.

xii Service Guide

CAUTION:
All IBM laser modules are designed so that there is never any human access to
laser radiation above a class 1 level during normal operation, user maintenance,
or prescribed service conditions. Data processing environments can contain
equipment transmitting on system links with laser modules that operate at
greater than class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle. Only trained service personnel should
perform the inspection or repair of optical fiber cable assemblies and receptacles.

xiv Service Guide

Data Integrity and Verification

IBM computer systems contain mechanisms designed to reduce the possibility of
undetected data corruption or loss. This risk, however, cannot be eliminated. Users who
experience unplanned outages, system failures, power fluctuations or outages, or
component failures must verify the accuracy of operations performed and data saved or
transmitted by the system at or near the time of the outage or failure. In addition, users
must establish procedures to ensure that there is independent data verification before
relying on such data in sensitive or critical operations. Users should periodically check
the IBM support websites for updated information and fixes applicable to the system and
related software.

Powering Off and Powering On the System

This section provides procedures for powering off and powering on the system.

Powering Off the System

If the system is operating under AIX, type the shutdown command to power off the
system.

If you cannot use this method, you can power off the system by using the following
operator-panel power button procedure:

Attention: Using the operator-panel power button to power off the system might

cause unpredictable results in the data files, and the next IPL will take longer to
complete.

1. Open the access door.

2. Press the power button on the operator panel.

B0FF appears in the operator panel display. The operator panel power LED starts

blinking at a fast rate.

When

the power-off sequence is complete, the system goes into standby power mode,

as evidenced by the following:

v OK displays in the operator panel display.

v The operator panel power LED starts blinking at a slow rate.

Powering On the System

Perform the following steps to power on the system:

1. Open the access door. Look for OK on the operator panel display, which indicates

that the system is in standby mode.

2. Press the power button on the operator panel.

The power LED on the operator panel starts blinking at a fast rate. Checkpoint
codes (9xxx) appear in the operator panel display. For details, see “IPL Flow” on
page 83.

When

the power-on sequence is complete, the power LED on the operator panel stops

blinking and stays on.

Powering Off and Powering On the System Using the Service Processor

The system can be powered off and on using the System Power Control menu, which is
a service processor menu that is available to the privileged user. See “System Power
Control Menu” on page 262.

Console Strategy

The firmware starts a console-selection sequence at system boot time if any of the
following is true:

v A console has not yet been selected.

v A previous console selection sequence timed out.

v A change in the system configuration affects the console (keyboard

installed/removed, mouse installed/removed, graphics adapter installed/removed or
moved to another PCI slot).

The

console-selection sequence allows you to select (from the appropriate input device)

one of the available console devices. If no console is selected within approximately 60
seconds, serial port 1 (S1) is selected as the console and the selection sequence times
out.

After a console has been selected, the console-selection sequence is only started at
boot time if there is a change in the system configuration (as described above), or the
contents of the system’s nonvolatile memory (NVRAM) are lost.

Note: Moving an ASCII terminal from one serial port to another (from S1 to S2) cannot

be detected by the firmware, so it does not constitute a configuration change.

You can also initiate a firmware console selection sequence from the System
Management Services (SMS) menus.

Power-On Self-Test

After power is turned on and before the operating system is loaded, the system does a
power-on self-test (POST). This test performs checks to ensure that the hardware is
functioning correctly before the operating system is loaded. During the POST, a POST
screen displays and POST indicators appear on the fimware console (if one is
connected). The next section describes the POST indicators and functions that can be
accessed during the POST.

POST Indicators

POST (power-on self-test) indicators indicate tests that are being performed as the
system is preparing to load the operating system. The POST indicators are words that
display on the system console. Each time that the system starts another step in the
POST, a POST indicator word appears on the console. Each word is an indicator of the
tests that are being performed.

The POST screen displays the following words:

Memory Memory test

Keyboard Initialize the keyboard and mouse. The window for pressing a key to

access the System Management Services, or to initiate a service
mode boot, is now open. See “POST Keys” for more information.

Network Self-test on network adapters

SCSI Adapters are being initialized

Speaker Sounds an audible tone at the end of POST

POST Keys

The POST keys, if pressed after the keyboard POST indicator displays and before the
last POST indicator (speaker) displays, cause the system to start services or to initiate
service mode boots used for configuring the system and diagnosing problems. The keys
are described below:

Note: The program function keys (F1-F12) on a keyboard attached to the system unit

are no longer used and will be ignored during POST. After the keyboard POST
indicator displays, you must use the numeric number keys to enter input.

1 Key

The numeric 1 key, when pressed during POST, starts the System Management
Services (SMS) interface.

5 Key

The numeric 5 key, when pressed during POST, initiates a system boot in service mode
using the default service mode boot list.

This mode attempts to boot from the first device of each type found in the list. It does
not search for other bootable devices of that type if the first device is not bootable.
Instead, it continues to the next device type in the list. The firmware supports up to five
entries in the boot list.

The default boot sequence is:

1. Diskette

2. CD-ROM

3. Hard file

4. Tape drive (if installed)

5. Network
a. Token ring
b. Ethernet

6 Key

The numeric 6 key works like the numeric 5 key, except that firmware uses the
customized service mode bootlist that was set up using the AIX service aids.

8 Key

To enter the open firmware command line, press the numeric 8 key after the word
keyboard displays and before the last word (speaker) displays during startup. After you
press the 8 key, the remaining POST indicators display until initialization completes.

When initialization and POST are complete, the open firmware command line (an OK
prompt) displays.

The open firmware command line should only be used by service personnel to obtain
additional debug information.

To exit from the open firmware command prompt, type reset-all or power off the
system and reboot.
