Their location codes will always show that they are plugged into another part as components of the
server. Another example follows:, Un-P1-C9 is a dual in-line memory module (DIMM), with memory
DIMM (C9) 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.
Table 36. Unit type and locations

Location code labels
The location code label represents a physical part of the server. The following table describes the prefixes
of location code labels.
Note: These location code labels apply to system units only.
Table 37. Prefixes of location code labels for system units
Prefix Description Example
A Air-moving device Fan, blower
C Card connector IOP, IOA, DIMM, processor card
D Device Diskette, control panel
E Electrical Battery, power supply, ac charger
L Logical path SCSI target Integrated drive electronics (IDE) address, Fibre
Channel LUN
N Horizontal placement for an empty rack location
P Planar System backplane
T Port
U Unit
V Virtual planar
W Worldwide unique ID
X EIA value for an empty rack location
Y Firmware FRU
Worldwide unique identifier
The location code label for the worldwide unique identifier consists of the prefix W followed by a
maximum of 16 uppercase hexadecimal digits with no leading zeros. A location code might not include a
worldwide unique identifier. When present, the worldwide unique identifier location label follows the
location label of the resource that interfaces with the resource that has the worldwide unique identifier,
usually a port.
