Chapter 4. Location Codes

The RS/6000 7046 Model B50 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 format for the location code is a string of alphanumeric characters separated by
a dash (-), slash (/), pound sign (#), or period (.).
The base location is all of the information before the slash (/) or pound sign (#).
It identifies a device that is connected or plugged into the parent.
Extended location information follows the slash (/). It identifies a device that is
part of the parent, a connector, or a cable.
Cable information follows the pound sign (#). It identifies a cable that is
connected to the parent.
The following are examples:
P1-C1 Identifies a CPU card C1 plugged into planar P1.
P1-M1 Identifies a memory card M1 plugged into planar P1.
P1-K1 Identifies a keyboard attached to connector K1 on planar P1.
P1/S1 Identifies serial port 1 controller on planar P1, the connector for serial port
1, or the cable attached to the connector for serial port 1.
P1-I2/E3 Identifies Ethernet controller 3 on the card plugged into slot 2 (I2) on
planar P1, the connector for Ethernet controller 3, or the cable attached to
Ethernet controller 3.
P1-I2#E3 Identifies the cable attached to Ethernet controller 3 plugged into slot 2
(I2) on planar P1.
Sub-locations, such as memory modules on a base memory card or a specific SCSI
address, are identified by a period (.). The following are examples:
P1-M1.4 Identifies DIMM 4 on memory card 1 on planar 1.
