DANGER
vi Finding parts, locations, and addresses
Observe the following precautions when working on or around your IT rack system:
v Heavy equipment–personal injury or equipment damage might result if mishandled.
v Always lower the leveling pads on the rack cabinet.
v Always install stabilizer brackets on the rack cabinet.
v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest
devices in the bottom of the rack cabinet. Always install servers and optional devices starting
from the bottom of the rack cabinet.
v Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top
of rack-mounted devices.
v Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in
the rack cabinet when directed to disconnect power during servicing.
v Connect all devices installed in a rack cabinet to power devices installed in the same rack
cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power
device installed in a different rack cabinet.
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.
CAUTION
v Do not install a unit in a rack where the internal rack ambient temperatures will exceed the
manufacturer's recommended ambient temperature for all your rack-mounted devices.
v Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not
blocked or reduced on any side, front, or back of a unit used for air flow through the unit.
v Consideration should be given to the connection of the equipment to the supply circuit so that
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To
provide the correct power connection to a rack, refer to the rating labels located on the
equipment in the rack to determine the total power requirement of the supply circuit.
v (For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets
are not attached to the rack. Do not pull out more than one drawer at a time. The rack might
become unstable if you pull out more than one drawer at a time.
v (For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless
specified by the manufacturer. Attempting to move the drawer partially or completely out of the
rack might cause the rack to become unstable or cause the drawer to fall out of the rack.
(R001)
Safety notices vii
CAUTION:
Removing components from the upper positions in the rack cabinet improves rack stability during
relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a
room or building:
v Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack
cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you
received it. If this configuration is not known, you must observe the following precautions:
– Remove all devices in the 32U position and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
– Ensure that there are no empty U-levels between devices installed in the rack cabinet below the
32U level.
v If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from
the suite.
v Inspect the route that you plan to take to eliminate potential hazards.
v Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the
documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.
v Verify that all door openings are at least 760 x 230 mm (30 x 80 in.).
v Ensure that all devices, shelves, drawers, doors, and cables are secure.
v Ensure that the four leveling pads are raised to their highest position.
v Ensure that there is no stabilizer bracket installed on the rack cabinet during movement.
v Do not use a ramp inclined at more than 10 degrees.
v When the rack cabinet is in the new location, complete the following steps:
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet.
– If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest
position to the highest position.
v If a long-distance relocation is required, restore the rack cabinet to the configuration of the rack
cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent.
Also lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the
pallet.

x Finding parts, locations, and addresses
Finding parts, locations, and addresses
Locate physical part locations and identify parts with system diagrams.
You can identify the enclosure in which a field replaceable unit (FRU) is plugged by its location code. The
first character of the location code is always U followed by a 4–character feature code or enclosure type
as shown in the following example: U789C.001.10ABCDE-P3-C31 In this example, the enclosure type is
789C.
The next 3 characters of the location code indicate the model of the enclosure (001 in the example). The
next string of characters provides the enclosure serial number (10ABCDE in the example).
Using this information, locate the enclosure with the FRU you want to replace. Find the enclosure type in
the following table and go to the service guide for that enclosure.

Part locations and location codes
You can find part locations by using location codes. Illustrations are provided to help you map a location
code to a position on the server or expansion unit.
8202-E4B or 8205-E6B
The information provided in this topic defines specific sections of a location code string. Use this
information to understand the meaning of a location code.
Using location codes
Use the following table to link to a specific topic that you need additional information about when
reading your location code.
Location code topics Description
“Location code overview” on page 4 Contains background information on the use of location
codes.
“Physical location codes” on page 4 Provides a definition for physical location code.
“Logical location codes” on page 4 Provides a definition of what a logical location code is.
Finding parts, locations, and addresses 3
Location code topics Description
“Location code format” on page 5 Provides descriptive information of the Un value in the
location code string. For example, U789C.001.
“Location code labels” on page 6 Provides a table that identifies and defines the location
code labels. The location code labels begin with an
alphabetic character and follow the system serial number.
For example, U789C.001.10ABCDE-P3-C31-T2-L23. The
system serial number is 10ABCDE in the previous
example. P3, C31, T2, and L23 all contain an alphabetic
character that is identified in the Location code labels
table.
“Worldwide unique identifier” on page 6 Provides a definition for the world unique identifier. This
group of digits follows the resource code labels and
always begins with the letter W.
Location code overview
Servers (system unit and expansion units) use physical location codes to provide mapping of replaceable
units. Location codes are produced by the server's firmware, which structures them so that they can be
used to identify specific parts in a system. The location code format is the same for all servers.
If you are working with a specific location code, the unit type and model immediately follow the first
character (Utttt.mmm). Match the unit type and model to a link, as shown in the Unit type and locations
table.
If the location code ends with -Txx-Lxx, the server's firmware could not identify the physical location.
When a physical location cannot be identified, a logical location code is provided. Where logical location
codes occur in enclosures, the locations topic for the enclosure has the known conversions listed. For
logical location codes with no conversion, contact your next level of support.
If the location code begins with UTMPx, the expansion I/O unit's machine type, model, and serial
number have not been set yet and this is a temporary unit identifier. To identify the unit, examine the
display panels on all of the expansion I/O units that are connected to the server until you find one with
the same characters in the first 5 digits of the top line in the unit's display. Record the unit's real machine
type and model from the unit label. Match the unit's machine type and model in the Unit type and

Physical location codes
Physical location codes provide a mapping of logical functions and components (such as backplanes,
removable modules, connectors, ports, cables, and devices) to their specific locations within the physical
structure of the server.
Logical location codes
If the physical location cannot be mapped to a physical location code, the server's firmware generates a
logical location code. A logical location code is a sequence of location labels that identifies the path that
the system uses to communicate with a given resource.
Note: A resource has as many logical location codes as it has logical connections to the system. For
example, an external tape device connected to two I/O adapters has two logical location codes.
4 Finding parts, locations, and addresses
An example of a logical location code is:
U789C.001.10ABCDE-P3-C31-T2-L23
The first part of the location code (through the T2 label) represents the physical location code for the
resource that communicates with the target resource. The remainder of the logical location code (L23)
represents exactly which resource is indicated.
Location code format
The location code is an alphanumeric string of variable length, consisting of a series of location
identifiers, separated by a dash. An example of a physical location for a fan is Un-A1.
The first position, represented by Un (where n is equal to any string contained between the U and the
hyphen) in the preceding example, is displayed in one of the forms in the following table.
Note: In location codes the U is a constant digit; however, the numbered positions that follow the U are
variables and are dependent on your server. Each column defines the numbers that follow the U in the
beginning of the location code.
Machine type and model number in a location code Feature codes and sequence numbers in a location code
Utttt.mmm.sssssss-A1 Uffff.ccc.sssssss-A1
The leftmost code is always U. The leftmost code is always U.
tttt represents the unit type of the enclosure (drawer or
node).
mmm represents the model of the enclosure. ccc represents the sequence number of the enclosure .
sssssss represents the serial number for the enclosure. sssssss represents the serial number of the enclosure.
Note: The mmm or ccc number might not be displayed on all location codes for all servers. If the mmm value is not
displayed, the location code is displayed in one of the following forms:
v Utttt.sssssss-A1
v Uffff.sssssss-A1
ffff represents the feature code of the enclosure (drawer
or node).
The location code is hierarchical; that is, each location identifier in the string represents a physical part.
The order (from left to right), in which each identifier is shown, allows you to determine which parts
contain other parts in the string.
The dash (-) separator character represents a relationship between two components in the unit. In the
example of the fan, whose location code is Un-A1, the dash shows that the fan (A1) is contained in the
base unit (or Un). Modules, adapters, cables, and devices are all parts that are plugged into another part.
Their location codes always show that they are plugged into another part as components of the server.
Another example follows: Un-P1-C9 is a memory DIMM (C9) that is plugged into a backplane (P1),
which is inside the unit (Un).
Note: For devices, certain error conditions might cause an IBM i device to display the device location in
an AIX®format.

Location code overview
Servers (system unit and expansion units) use physical location codes to provide mapping of replaceable
units. Location codes are produced by the server's firmware, which positions them so that they can be
used to identify specific parts in a system. The location code format is the same for all servers.
If you are working with a specific location code, the unit type and model immediately follow the first
character (Utttt.mmm). Match the unit type and model to a link, as shown in the Unit type and locations
table.
If the location code ends with -Txx-Lxx, the server's firmware could not identify the physical location.
When a physical location cannot be identified, a logical location code is provided. Where logical location
codes occur in enclosures, the locations topic for the enclosure has the known conversions listed. For
logical location codes with no conversion, contact your next level of support.
If the location code begins with UTMPx, the machine type, model, and serial number of the expansion
I/O unit have not been set yet, and this is a temporary unit identifier. To identify the unit, examine the
display panels on all of the expansion I/O units that are connected to the server until you find one with
the same characters in the first 5 digits of the top line in the unit's display. Record the unit's real machine
type and model from the unit label. Match the unit's machine type and model in the Unit type and
locations table and follow the link to determine the service information.
Note: Locations for units that are not in the preceding list are either not supported or there is a problem
in the firmware. Contact your next level of support.
Physical location codes
Physical location codes provide a mapping of logical functions and components (such as backplanes,
removable modules, connectors, ports, cables, and devices) to their specific locations within the physical
structure of the server.
Logical location codes
If the physical location cannot be mapped to a physical location code, the server's firmware generates a
logical location code. A logical location code is a sequence of location labels that identifies the path that
the system uses to communicate with a given resource.
Note: A resource has as many logical location codes as it has logical connections to the system. For
example, an external tape device connected to two I/O adapters has two logical location codes.
An example of a logical location code is:
U789C.001.10ABCDE-P3-C31-T2-L23
The first part of the location code (through the T2 label) represents the physical location code for the
resource that communicates with the target resource. The remainder of the logical location code (L23)
represents which resource is indicated.
Location code format
The location code is an alphanumeric string of variable length, consisting of a series of location
identifiers, separated by a dash. An example of a physical location for a fan is Un-A1.
The first position, represented by Un (where n is equal to any string contained between the U and the
hyphen) in the preceding example, is displayed in one of the forms in the following table.
16 Finding parts, locations, and addresses
Note: In location codes the U is a constant digit; however, the numbered positions that follow the U are
variables and are dependent on your server. Each column defines the numbers that follow the U in the
beginning of the location code.
Machine type and model number in a location code Feature codes and sequence numbers in a location code
Utttt.mmm.sssssss-A1 Uffff.ccc.sssssss-A1
The leftmost code is always U. The leftmost code is always U.
tttt represents the unit type of the enclosure (drawer or
node).
mmm represents the model of the enclosure. ccc represents the sequence number of the enclosure .
sssssss represents the serial number for the enclosure. sssssss represents the serial number of the enclosure.
Note: The mmm or ccc number might not be displayed on all location codes for all servers. If the mmm value is not
displayed, the location code is displayed in one of the following forms:
v Utttt.sssssss-A1
v Uffff.sssssss-A1
ffff represents the feature code of the enclosure (drawer
or node).
The location code is hierarchical; that is, each location identifier in the string represents a physical part.
The order (from left to right), in which each identifier is shown, helps you determine which parts contain
other parts in the string.
The dash (-) separator character represents a relationship between two components in the unit. In the
example of the fan, whose location code is Un-A1, the dash shows that the fan (A1) is contained in the
base unit (or Un). Modules, adapters, cables, and devices are all parts that are plugged into another part.
Their location codes always show that they are plugged into another part as components of the server.
Another example follows: Un-P1-C9 is a memory DIMM (C9) that is plugged into a backplane (P1),
which is inside the unit (Un).
Note: For devices, certain error conditions might cause an IBM i device to display the device location in
an AIX format.
