fabric Fibre Channel-defined interconnection methodology that supports high-speed

data routing in Fibre Channel networks.

fault LED During power up and self test, the 4x50 Fault LED comes on. After self test, if

this LED remains on or comes on, the 4x50 has a problem with one of its

components. During normal operation, this LED should be off.

FC-AL An acronym for Fibre Channel Arbitrated Loop topology.

FC adapter A printed circuit assembly that translates data between the FC host processor's

internal bus and the FC link. This is also known as an HBA, or Host Bus

Adapter.

FC device A device that uses Fibre Channel communications.

FC port An opening at the back of the 4x50 that provides a fiber optic connection

between the FC adapter and the FC host.

FC-SCSI hardware

path ID

A FC term describing a list of values showing the physical hardware path of

the FC host to the target device.

FC-SW An acronym for Fibre Channel switched topology. The highest performance

Fibre Channel fabric, providing a choice of multiple path routings between

pairs of F-ports.

FDDI An acronym for the Fibre Distributed Data Interface. ANSI’s architecture for a

metropolitan area network; a network based on the use of optical fibre cable

to transmit data at 100 MBsc.

fiber A fiber optic cable made from thin strands of glass through which data in the

form of light pulses is transmitted (LASER, LED). It is often used for high-speed

transmission over medium (200m) to long (10km)distances but it can be used

for short distances (<200m).

fibre A generic FC term used to cover all transmission media types specified in the

Fibre Channel Physical Layer standard (FC-PH), such as optical fiber, copper

twisted pair, and copper coaxial cable.

Fibre Bridge Bi-directional connectivity for data transfers between fibre and SCSI.

Fibre Channel (FC) A switched protocol that allows concurrent communication among

workstations, supercomputers, mainframes, data storage devices, and other
