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 four-wire power cable and plug for the user’s

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.

Location Codes
This system unit uses physical location codes in conjunction with AIX location codes to
provide mapping of the failing field replaceable units. The location codes are produced
by the system unit’s firmware and AIX.
Physical Location Codes
Physical location codes provide a mapping of logical functions in a platform (or
expansion sites for logical functions, such as connectors or ports) to their specific
locations within the physical structure of the platform.
Location Code Format
The location code is an alphanumeric string of variable length, consisting of a series of
location identifiers, separated by a dash (-), slash (/), or a pound sign (#) character. The
series is hierarchical; that is, each location identifier in the string is a physical or logical
child of the one preceding it.
Chapter 1. Reference Information 9
v The - (dash) separator character represents a normal structural relationship where
the child is a separate physical package and it plugs into (or is connected to) the
parent. For example, P1-C1 is a processor card (C1) plugged into a planar (P1), or
P1-M1 is a memory card (M1) plugged into a planar (P1).
v The / (slash) separator character separates the base location code of a function from
any extended location information. A group of logical devices can have the same
base location code because they are all on the same physical package, but may
require extended location information to describe the connectors they support. For
example, P2/S1 describes the location of the serial port 1 controller and its connector
(S1), which is located on planar P2 (its base location code), but the / indicates that
further devices can be connected to it at the external S1 serial connector. The
keyboard controller and its connector likewise have location code P2/K1, which
means they have the same base location code (P2) as serial port 1, but a different
external connector. In contrast, the location code P2-K1 actually points to the device
connected to connector K1; that is, the keyboard. The location code P2/Z1 indicates
an integrated SCSI controller which drives connector Z1, while location codes of
P2-Z1-... point to the actual SCSI bus and devices.
v The # (pound sign) separator character indicates a cable connection between a
connector and parent.
The following are examples:
v P1-C1 identifies processor card C1 plugged into planar P1.
v P1-M1 identifies memory card M1 plugged into planar P1.
v P2/S1 identifies serial port 1 controller on I/O board P2, or the connector for serial
port 1.
v P1-K1 identifies a keyboard attached to connector K1 on planar P1.
v P2/Z1 identifies an integrated SCSI controller on planar P2 which drives connector
Z1.
v P2-Z1-... points to the actual SCSI bus and devices attached to Z1.
The . (period) identifies sub locations (DIMMs on a memory card, or SCSI addresses).
The following are examples:
v P1-M1.4 identifies memory DIMM 4 on memory card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3
attached to SCSI bus 1, which is integrated on planar P2.
v P2.1 identifies a riser card plugged into planar P2.
AIX Location Codes
The basic formats of the AIX location codes are as follows:
v For non-SCSI devices/drives:
– AB-CD-EF-GH
v For SCSI devices/drives:
– AB-CD-EF-G,H
10 Service Guide
For planars, cards, and non-SCSI devices, the location code is defined as follows:
AB-CD-EF-GH
||||
| | | Device/FRU/Port ID
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
v The AB value identifies a bus type or PCI parent bus as assigned by the firmware.
v The CD value identifies adapter number, the adapter’s devfunc number, or physical
location. The devfunc number is defined as the PCI device number times 8, plus the
function number.
v The EF value identifies a connector.
v The GH value identifies a port, address, device, or FRU.
Adapters and cards are identified only with AB-CD.
The possible values for AB are:
00 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA buses
xy For PCI adapters where x is equal to or greater than 1. The x and y are characters in the
range of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parent
bus’s ″ibm, aix-location″ open firmware property.
The possible values for CD depend on the adapter/card:
v For pluggable PCI adapters/cards, CD is the device’s devfunc number (PCI device
number times 8, plus the function number). The C and D are characters in the range
of 0-9, and A-F (hex numbers). Location codes therefore uniquely identify multiple
adapters on individual PCI cards.
v For pluggable ISA adapters, CD is equal to the order of the ISA cards
defined/configured either by SMIT or the ISAAdapter Configuration Service Aid.
v For integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases, this code is equal to the adapter’s physical location code. In
cases where a physical location code is not available, CD will be FF.
EF is the connector ID, used to identify the adapter’s connector to which a resource is
attached.
GH is used to identify a port, device, or FRU. For example:
v For async devices, GH defines the port on the fanout box. The values are 00 to 15.
v For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.
v For all other devices, GH is equal to 00.
Chapter 1. Reference Information 11
For integrated adapters, EF-GH is the same as the definition for a pluggable adapter.
For example, the location code for a diskette drive is 01-D1-00-00. A second diskette
drive is 01-D1-00-01.
For SCSI devices, the location code is defined as follows:
AB-CD-EF-G,H
| | |||
| | | | Logical Unit address of the SCSI Device
| | | Control Unit Address of the SCSI Device
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
Where
AB-CD-EF are the same as non-SCSI devices.
G defines the control unit address of the device. Values of 0 to 15 are valid.
H defines the logical unit address of the device. Values of 0 to 255 are valid.
A bus location code that is also generated as ’00-XXXXXXXX’ where XXXXXXXX is
equivalent to the node’s unit address.
Examples of physical location codes displayed by AIX are as follows:
v First processor card plugged into planar 1:
P1-C1
v Second memory card in planar P1:
P1-M2
v Memory DIMM 12 on second memory card plugged into planar P1:
P1-M2.12

Examples of AIX location codes displayed are as follows:
v Integrated PCI adapter as follows:
10-80 Ethernet
10-60 Integrated SCSI Port 1 (internal)
10-88 Integrated SCSI Port 2 (external)
v Pluggable PCI adapters as follows:
20-58 to 20-5F Any PCI card in slot 1
20-60 to 20-67 Any PCI card in slot 2
10-68 to 10-6F Any PCI card in slot 3
10-70 to 10-77 Any PCI card in slot 4
10-78 to 10-7F Any PCI card in slot 5
v Integrated ISA adapters as follows:
01-D1 Diskette adapter
01-R1 Parallel port adapter
01-S1 Serial port 1 adapter
