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

Laser Safety Information
CAUTION:
Energy hazard, remove power before servicing. Disconnect two power supply cords.
C23
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.
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.

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.

primary I/O drawer operator panel can be pushed to initialize the system. Progress indicators, also referred
to as checkpoints, are visible on the primary I/O drawer operator panel display and the power LED on the
primary I/O drawer stops blinking and stays on, indicating the system power is on.
The CEC drawer and secondary I/O drawers are powered on through the primary I/O drawer system
power control network (SPCN). When power is applied, the power LEDs on the primary I/O drawer go
from blinking to on continuously, and the power LED on the CEC drawer and secondary I/O drawer(s)
comes on and stays on. This indicates that power levels are satisfactory in the drawers.
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 pressing the power button on the primary I/O drawer
operator panel.
Attention: Using the power button on the operator panel to power off the system can cause
unpredictable results in the data files, and the next IPL will take longer to complete.
For complete details on how to power on and off the system, go to “Powering Off and Powering On the
System” on page 415 and “System Power-On Methods” on page 386.

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 has affected the console (keyboard installed/removed, mouse
installed/removed, graphics adapter installed/removed or moved to another PCI slot).
console-selection sequence allows you to select (from the appropriate input device) any one of the
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.
Attention: If an ASCII terminal is attached to serial port 1 (S1), and there is any interaction with this
terminal, then:
v After OK displays in the operator panel,
AND
v Before the power-on sequence is initiated,
firmware will use this terminal as the console, regardless of the previous console selection.
the
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 previously described), 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 system console-selection sequence from the 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 system console (if one is connected). The next section describes the POST indicators and functions
that can be accessed during the POST.
POST Indicators
POST 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 a different 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 list, is now open. See “POST
Keys” on page 7 for more information.
Network Self-test on network adapters
SCSI Adapters are being initialized
Speaker Sounds an audible tone at the end of POST
6 Service Guide
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.
Chapter 1. Reference Information 7
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 in System Management Services or in 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.
Use the open firmware command line to set up adapters that are not configurable with the System
Management Services. Your adapter documentation directs you to use this option if it is needed.
To exit from the open firmware command prompt, type reset-all or power off the system and reboot.

System Locations
The system consists of a minimum of two drawers in one rack: the CEC drawer and the primary I/O
drawer. These two components are connected by cables that transmit data and control signals. Additional
I/O drawers can be added if further expansion of the system is required. The following figure shows the
system units.
