PCBA Printed circuit board assembly.
PCM Pulse-code modulation. A standard method of encoding analog audio signals
in digital form.
Performance An HP StorageWorks switch feature that monitors port traffic and includes frame
Monitoring counters, SCSI read monitors, SCSI write monitors, and other types of monitors.
phantom address An AL_PA value that is assigned to a device that is not physically in the loop.
Also called phantom AL_PA.
phantom device A device that is not physically in an arbitrated-loop but is logically included
through the use of a phantom address.
PID Port identifier. As defined in FC-FG, bits 7 through 0 of an address identifier.

PKI Public key infrastructure. An infrastructure that is based on public key
cryptography and CA and that uses digital certificates.
See also CA,
PKI certification Public key infrastructure certification utility. A utility that makes it possible to
utility collect certificate requests from switches and to load certificates to switches.

PLDA Private loop direct-attached. A technical report specifying a logical loop.
PLOGI Port login. The port-to-port login process by which initiators establish sessions
with targets.
See also FLOGI.
point-to-point A Fibre Channel topology that employs direct links between each pair of
communicating entities.
See also topology.
port In an HP StorageWorks switch environment, an SFP or GBIC receptacle on a
switch to which an optic cable for another device is attached.
port address In Fabric OS, a port address can be defined by a domain and port number
combination or by area number. In an ESCON Director, an address is used to
specify port connectivity parameters and to assign link addresses for attached
channels and control units.
See ESCON.
port cage The metal casing extending out of the optical port on the switch, into which the
SFP can be inserted.
port card A hardware component that provides a platform for field-replaceable, hot
swappable ports.
port group A group of adjacent ports that share a common pool of frame buffers for
long-distance connections.
port-level zoning A process that defines a zone member by domain,port, which is the physical
port to which the member is connected.
