Glossary
failover
Automatic and nondisruptive transition of functions from an active FRU that has failed to a
backup FRU.
FAN
See fabric address notification.
FC-0
The Fibre Channel layer that describes the physical link between two ports, including the
transmission media, transmitter and receiver circuitry, and interfaces. This consists of a pair of
either optical fiber or electrical cables (link media) along with transceiver circuitry which work
together to convert a stream of bits at one end of the link to a stream of bits at the other end.
FC-1
Middle layer of the Fibre Channel physical and signaling interface (FC-PH) standard, defining
the 8B/10B encoding/decoding and transmission protocol.
FC-2
The Fibre Channel layer that specifies the signaling protocol, rules, and mechanisms required to
transfer data blocks. The FC-2 layer is very complex and provides different classes of service,
packetization, sequencing, error detection, segmentation, and reassembly of transmitted data.
FC-3
The Fibre Channel layer that provides a set of services common across multiple node ports
(N_Ports) of a Fibre Channel node. The services are not commonly used and are essentially
reserved for Fibre Channel architecture expansion.
FC-4
The Fibre Channel layer that provides mapping of Fibre Channel capabilities to upper level
protocols (ULP), including Internet protocol (IP) and small computer system interface (SCSI).
FC-AL
Acronym for Fibre Channel arbitrated loop. Synonymous with
FCC-IOC
See Fibre Channel input/output
FC-PH

feature enablement key
After purchasing a an additional product feature, HP provides a unique feature enablement key
to the customer. A feature key is a case-sensitive alphanumeric string consisting of dashes,
uppercase characters, and lowercase characters.
