fiber optics
Branch of optical technology concerned with the transmission of light pulses through fibers
made of transparent materials such as glass, fused silica, and plastic.
fiber port module card
A 1 gigabit per second module that contains four generic ports (G_Ports). Each fiber module
card provides connections through duplex small form factor pluggable (SFP) fiber optic
transceivers.
FICON
An IBM set of products and services introduced in 1999 that is based on the Fibre Channel
Standard. FICON technology uses fiber optic cables as the data transmission medium and
significantly improves I/O performance (including 1 Gbps bidirectional data transfer).
FICON Management Server
An optional feature that can be enabled on the director or switch through the Product Manager
application. When enabled, host control and management of the director or switch is provided
through an S/390 Parallel Enterprise or zSeries server attached to a director or switch port.
field-replaceable unit
(FRU) — Assembly removed and replaced in its entirety when any one of its components fails.
See also active FRU.
firmware
Embedded program code that resides and executes on directors, switches, and hubs.
FPM card
See fiber port module card.
F_Port
See fabric port.
FRU
See field-replaceable unit.
gateway
A multi-homed host used to route network traffic from one network to another, and to pass
network traffic from one protocol to another.
gateway address
A unique string of numbers (in the format xxx.xx.xxx.xxx) that identifies a gateway on the
network.
generic port
(G_Port) — Physical interface on a director that can function either as a fabric port (F_Port) or
an expansion port (E_Port) depending on the port type to which it connects.
