382 Fibre Channel Interface Manual, Rev. D
Power on state
In this state, any circuits or optical devices respond to controls resulting from higher levels.
ppm
Parts per million.
Preferred Address
On FC-AL, the AL_PA which an NL_Port attempts to acquire first during loop initialization. Following power-on
reset, the preferred address of a private NL_Port is its hard address (if any). Following receipt of a LIP other
than LIP(AL_PD,AL_PS), the preferred address of a private NL_Port is its previously acquired address. Fabric-
assigned or soft addresses are not considered to be preferred.
Previously Acquired Address
This address only has meaning during loop initialization. During initialization, it is the AL_PA which was in use
prior to receipt of LIP. After the time a loop initialization completes and the next one begins, an NL_Port has no
previously acquired address.
Primitive Sequence
An ordered set transmitted repeatedly and continuously until a specified response is received.
Primitive Signal
An ordered set designated to have a special meaning such as an Idle or Receiver_Ready (R_RDY).
Private loop device
A device with only private NL_Ports.
Private NL_Port
An NL_Port which is observing the rules of private loop behavior.
PRLI
Process Login.
PRLO
Process Logout.
Process policy
An error handling policy where an N_Port is able to continue processing Data frames received following detec-
tion of one or more missing frames in a sequence.
Process_Associator
A value used in the Association_Header to identify a process or a group of processes within a Node.
Process_Associator is the mechanism by which a process is addressed by another communicating process.
Process_Associator is a generic reference to Originator Process_Associator and Responder Process_ Associ-
ator (see Operation_Associator).
Profile
An interoperability specification that provides implementation guidelines for systems manufacturers, system
integrators, component manufacturers, and users seeking to design and select interoperable Fibre Channel
peripherals, hosts, and components. A Profile specifies particular settings for various Fibre Channel physical,
link-level, and upper-level protocol options to enhance interoperability.
