Rack Safety Instructions

v Do not install this unit in a rack where the internal rack ambient temperatures will

exceed 40 degrees C.

v Do not install this unit in a rack where the air flow is compromised. Any side, front or

back of the unit used for air flow through the unit must not be in direct contact with
the rack.

v Care should be taken to ensure that a hazardous condition is not created due to

uneven mechanical loading when installing this unit in a rack. If the rack has a
stabilizer it must be firmly attached before installing or removing this unit.

v Consideration should be given to the connection of the equipment to the supply

circuit so that overloading of circuits does not compromise the supply wiring or
overcurrent protection. To provide the correct power connection to the rack, refer to
the rating labels located on the equipment in the rack to determine the total power
requirement for the supply circuit.

v An electrical outlet that is not correctly wired could place hazardous voltage on the

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.

xi

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.

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.

DANGER

Do not attempt to open the covers of the power supply. Power supplies are
not serviceable and are to be replaced as a unit.

CAUTION:
This unit has more than one power supply cord. To reduce the risk of electrical
shock, disconnect two power supply cords before servicing.

xii Service Guide

Laser Safety Information

CAUTION:
This product may contain a CD-ROM which is a class 1 laser product.

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.

Preface xiii

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.

Overview

The RS/6000 Enterprise Server Model H80, Eserver pSeries 660 Models 6H0 and
6H1 are multiprocessor, multibus systems packaged in drawers. The processors and
memory are packaged in a 5 EIA-unit central electronics complex (CEC drawer), and
the I/O devices are in a 5 EIA-unit I/O drawer. The basic system consists of one CEC
drawer and one I/O drawer in the same rack. Connections between the CEC drawer
and I/O drawers are made through a number of cables, which include the V/S COMM
cable, RIO (remote input/output) cables, and JTAG cable.

Processors

The Model H80 and Model 6H1 can have one to six processors, of either of two
processor types, in various configurations:

v Minimum configuration is one 450 MHz processor, which has 2 MB of L2 cache.
v Two or four 450 MHz processors, each with 4 MB of L2 cache.
v Six 500 MHz processors, each with 4 MB of L2 cache.

OR

v Minimum configuration is either one 600 MHz processor, which has 2 MB of L2

cache, or one 750 MHz processor, which has 8 MB of L2 cache.

v One or two memory riser cards; each riser card has sixteen sockets. 128 MB, 256

MB, 512 MB, and 1 GB dual inline memory modules (DIMMs) are available.

v Certain 32 MB DIMMs from older RS/6000 systems can also be used when

upgrading the system memory.

Power is provided to the system rack through an ac power cord that is connected to a
distribution bus. Power is connected from the distribution bus to each drawer
independently. All drawers use 200 - 240 V ac power or -48 V dc power.

The primary I/O drawer has the following:

v 14 PCI slots
v System operator panel
v SPCN controller
v Interrupt and system bus control logic
v Service processor
v Optional boot DASDs
v Various connectors, including four serial port connectors, on the back of the drawer

for the attachment of external devices.

Note: Serial ports 1 and 2 can only be used to access the service processor menus.

No ″heartbeat″-type devices or cables can be used on these ports.
″Heartbeat″-type devices or cables must be installed on serial port 3 or serial
port 4.

The PCI bus speeds are as follows:

v Up to 33 Mhz for the four 32-bit slots at 5 V
v Up to 66 Mhz for the ten 64-bit slots at 3.3 V

Slots 1-5, 8-10, 13 and 14 support either 32- or 64-bit PCI adapters. The remaining
slots are 32-bit only.

The primary I/O drawer has space for up to three media devices (tape, CD-ROM, and
diskette drive). Two optional disk drives can occupy PCI slots 13 and 14.

The system data flow diagrams are shown in “Data Flow with One-Way Processor” on

Powering the System On and Off

The system can be powered on after the following cables are connected:

v V/S COMM Cable
v All RIO cables
v All SPCN cables
v JTAG Cable
v All PCI cables to supported drawers

4 Service Guide

After the required cables are installed, and the power cables are connected, the power
button on the 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 CEC drawer and primary I/O drawer go from blinking to on continuously, and the
power LED on the secondary I/O drawer 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
primary I/O drawer operator-panel power button.

Attention: Using the operator-panel power pushbutton 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 429 and “System Power-On Methods” on page 398.

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)
any 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.

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

the firmware will use this terminal as the console, regardless of the previous console
selection.

Chapter 1. Reference Information 5

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 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 firmware 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 time period 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 I/O drawer

are not used and will be ignored. After the keyboard POST indicator displays,
you must use the numeric number keys to enter input.

6 Service Guide

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.

System Unit 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. An additional I/O drawer can be added if further expansion of the
system is required. The following figure shows the units.
