file transfer protocol (FTP)
name is $DISK.SUBVOL.MYFILE. For files that are network accessible, the node
name precedes the volume name: \NODE.$DISK.SUBVOL.MYFILE.
file transfer protocol (FTP). A data communications protocol that is used for transferring
files between systems.
filler panel. A blank faceplate that is installed in place of a ServerNet adapter to ensure
proper ventilation within a system enclosure.
FIR. See FRU information record (FIR).
FIRINIT. A diagnostic task used to update the communications line interface processor
(CLIP) FRU information record (FIR) that is kept in the ServerNet wide area network
(SWAN) concentrator CLIP flash memory.
FIRMUP. A diagnostic task used to update the copy of the Portable Silicon Operating
System (pSOS) system product embedded kernel that is kept in the SWAN
concentrator communications line interface processor (CLIP) flash memory.
firmware. Code in memory that is necessary for the power-up initialization and
communication with a host or device. The software for components of the ServerNet
architecture (for example, an adapter) is called firmware. Some firmware for ServerNet
components is downloaded when the system or component is loaded.
fixed process configuration. Use of the Subsystem Control Facility (SCF) to configure a
generic process to always start in the first available processor (that is, to be fault
tolerant).
flash PROM. A type of programmable read-only memory (PROM) that is electrically
reprogrammable.
FOX. See Fiber Optic Extension (FOX).
FOX monitor process. The Fiber Optic Extension (FOX) monitor process for the
ServerNet/FX adapter subsystem. The process name is $ZZFOX.
FOX ring. The fiber-optic cabling that connects the FOX clusters. Also used to refer to the
topology of a FOX network.
FOXMON. See FOX monitor process.
FPGA. See field-programmable gate array (FPGA).
FRU. See field-replaceable unit (FRU).
FRU information record (FIR). A collection of information that every field-replaceable unit
(FRU) carries with it, such as part number, revision, track ID, and media access control
(MAC) address.
GB. See gigabyte (GB).
