Physical Location Codes

 

 

 

Physical location codes provide a mapping

of

logical functions

in a

expansion sites for logical functions, such

as

connectors or

ports) t

locations within the physical structure of

the platform.

 

Location

Code

Format

 

 

 

 

 

 

 

The format

for the

location

code

is

an

alphanumeric string

of varia

consisting

of a series of location identifiers, separated by the

slash

(/)

character. The series is

hierarchical;

that is,

each loc

string

is

a physical

child

of the

one

preceding

it.

 

ŸThe - (dash) separator character represents a normal structural

where

the child

is

a separate

physical package

and

it plugs

i

to) the

parent. For

example, P1-C1 is a CPU card

(C1)

plugged

in

(P1),

or

P1-M1 is

a

memory card

(M1) plugged into

a

planar (P1).

ŸThe / (slash) separator character separates the base location from any extended location information. A group of logical devices

same base location code because they are all on the same phy but may require extended location information to describe the

support.

For example, P2/S1 describes the location of the serial

and

its

connector (S1), which is located on

planar

P2 (its base

but

the

/ indicates that further devices

can be

connected to

serial connector. The keyboard controller and its connector likewise

location code

P2/K1,

which

means they

have the same base locat

as serial port

1,

but a

different

external connector. In contra

P2-K1 actually points to the device connected to connector K1; t

keyboard. The location code P2/Z1

indicates an integrated SCSI c

drives

connector Z1, while location

codes of P2-Z1-... point to

bus and

devices.

 

Each location identifier consists of one alpha prefix character tha type, and a decimal integer number (typically one or two digits) t specific instance of this location type. Certain location types may secondary sub-locations, which are indicated by appending a period and a sub-location instance number.
