field replaceable unit (FRU). An assembly that is
replaced in its entirety when any one of its components
fails. In some cases, a field replaceable unit can contain
other field replaceable units.
File Transfer protocol (FTP). In Transmission Control
protocol/Internet protocol (TCP/IP), an application
protocol used for transferring files to and from host
computers.
fill word. An IDLE or ARB ordered set that is
transmitted during breaks between data frames to keep
the Fibre Channel link active.
FLA. Fabric loop attach.
FLOGI. See fabric login .
FL_port. See fabric loop port .
F_port. See fabric port .
frame. The Fibre Channel structure used to transmit
data between ports. Consists of a start-of-frame
delimiter, header, any optional headers, the data
payload, a cyclic redundancy check (CRC), and an
end-of-frame delimiter. There are two types of frames:
link control frames (transmission acknowledgements,
and so on) and data frames.
frame delimiter. A part of an ordered set that marks
frame boundaries and describes frame contents. See
also
ordered set .
FRU. See field replaceable unit .
FS. See Fibre Channel service .
FSP. See Fibre Channel service protocol .
FSPF. See Fibre Channel shortest path first .
FTP. See file transfer protocol .
full duplex. A mode of communication that allows the
same port to simultaneously transmit and receive
frames. See also
half duplex .
Fx_port. A fabric port that can operate as either a
fabric port (F_port) or fabric loop port (FL_port). See
also
fabric port and fabric loop port .
gateway. Hardware that connects incompatible
networks by providing the necessary translation for both
hardware and software.
GBIC. See gigabit interface converter .
GBps. Gigabytes per second.
Gbps. Gigabits per second.
generic port (G_port). A generic port that can operate
as either an expansion port (E_port) or a fabric port
(F_port). A port is defined as a G_port when it is not yet
connected or has not yet assumed a specific function in
the fabric.
gigabit interface converter (GBIC). A removable
serial transceiver module designed to provide gigabaud
capability for Fibre Channel (FC) and other products
that use the same physical layer.
gigabit switch. A 16-port, Fibre Channel gigabit
switch.
G_port. See generic port .
half duplex. A mode of communication that allows a
port to either transmit or receive frames at any time, but
not simultaneously (with the exception of link control
frames, which can be transmitted at any time). See also
full duplex .
hard address. The arbitrated loop physical address
(AL_PA) that a node loop port (NL_port) attempts to
acquire during loop initialization.
hardware translative mode. Method for achieving
address translation. The two hardware translative
modes that are available to a QuickLoop-enabled switch
are standard translative mode and QuickLoop mode.
See also
standard translative mode and QuickLoop
mode .
HBA. See host bus adapter .
high availability. An attribute of the switch that
identifies it as being capable of operating well in excess
of 99 percent of the time. High availability is typically
identified by the number of nines in that percentage. For
example, a switch that is rated at five nines would be
capable of operating 99.999 percent of the time without
failure.
host bus adapter (HBA). The interface card between
a server or workstation bus and the Fibre Channel
network.
hot pluggable. A field replaceable unit (FRU)
capability that indicates it can be extracted or installed
while customer data is otherwise flowing in the chassis.
hub. A Fibre Channel wiring concentrator that
collapses a loop topology into a physical star topology.
Nodes are automatically added to the loop when active
and removed when inactive.
IC bus. A serial, 2-wire bus used to monitor field
replaceable unit (FRU) temperatures and control the
system including blade power control.
ID. Identification.
IDB. Interface descriptor block.
