FESA
FESA. See Fast Ethernet ServerNet adapter (FESA).
Fiber Optic Extension (FOX). Refers to two products, FOX II and ServerNet/FX, which
allow you to create high-speed (up to 4 megabytes/second) networks of as many as 14
systems connected by dual fiber-optic cables.
fiber-optic plug-in card (F-PIC). A plug-in card (PIC) for the 6760 ServerNet device
adapter (ServerNet/DA) that uses a fiber-optic interface to connect the adapter to
external disk drives and to some tape drives that contain a back-end board (BEB) that
translates fiber-optic signals from the F-PIC into SCSI commands and information for
the tape drive. See also plug-in card (PIC) and SCSI plug-in card (S-PIC).
fiber optics. A medium for data transmission that conveys light or images through very fine,
flexible, glass or plastic fibers. Fiber-optic cables (light guides) are a direct replacement
for conventional coaxial and wire pairs.
fiber-optic ServerNet addressable controller (F-SAC). A ServerNet addressable
controller (SAC) that is contained within a fiber-optic plug-in card (F-PIC).
fiber-optic ServerNet cable. A ServerNet cable that uses fiber optics to transmit data. HP
NonStop™ servers support two types of fiber-optic ServerNet cables: multimode
fiber-optic (MMF) ServerNet cable and single-mode fiber-optic (SMF) ServerNet cable.
Fibre Channel ServerNet adapter (FCSA). A ServerNet adapter that transmits data
between an HP NonStop™ server and Fibre Channel storage devices. This ServerNet
adapter is installed in an IOAM enclosure.
Fibre Channel switch (FC switch). Networking hardware that can connect an Enterprise
Storage System and an HP NonStop™ server. This switch allows any-to-any
connectivity.
field. In a structured programming language, an addressable entry within a data structure.
The term field is sometimes used to mean member.
field-programmable gate array (FPGA). A programmable integrated circuit that can be
customized to perform specific functions.
field-replaceable unit (FRU). A unit that can be replaced in the field only by qualified
personnel trained by HP and cannot be replaced by customers. A unit is classified as a
FRU because of safety hazards such as weight, size, sharp edges, or electrical
potential; contractual agreements with suppliers; or national or international standards.
See also customer-replaceable unit (CRU).
FIFO. A type of Open System Services (OSS) special file that is always read and written in
a first-in, first-out manner.
FIFO special file. See FIFO.
