For a translation of the safety notices contained in this book, see the
System Unit
Safety Information
, order number SA23-2652.
Rack Safety Instructions
vDo not install this unit in a rack where the internal rack ambient temperatures will
exceed 40 degrees C.
vDo 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.
vCare 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.
vConsideration 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.
vAn 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.

Chapter 1. Reference Information
This chapter provides an overview of the system, including a logical description and a
physical overview. Additional details pertaining to the system are also provided. These
include:
vMemory overview and placement
vGeneral description of the operator panel
vCabling rules
vSystem location rules and descriptions
vPowering on and off the system
vPower flow
vData flow
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:
vMinimum configuration is one 450 MHz processor, which has 2 MB of L2 cache.
vTwo or four 450 MHz processors, each with 4 MB of L2 cache.
vSix 500 MHz processors, each with 4 MB of L2 cache.
OR
vMinimum 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.
vTwo or four 600 MHz processors, each with 4 MB of L2 cache.
vTwo or four 750 MHz processors, each with 8 MB of L2 cache.
vSix 668 MHz processors, each with 8 MB of L2 cache.
vSix 750 MHz processors, each with 8 MB of L2 cache.
The Model 6H0 can have one to four processors, of either of two processor types, in
various configurations:
vMinimum configuration is one 450 MHz processor, which has 2 MB of L2 cache.
vTwo or four 450 MHz processors, each with 4 MB of L2 cache.
OR
1

vMinimum 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.
vTwo or four 600 MHz processors, each with 4 MB of L2 cache.
vTwo or four 750 MHz processors, each with 8 MB of L2 cache.
Memory
v256 MB (minimum) to 32 GB (maximum)
vOne 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.
vCertain 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:
v14 PCI slots
vSystem operator panel
vSPCN controller
vInterrupt and system bus control logic
vService processor
vOptional boot DASDs
vVarious 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:
vUp to 33 Mhz for the four 32-bit slots at 5 V
vUp 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
page 3 and “Data Flow with Two- to Six-Way Processor” on page 4.
