FICON Management Server
An optional feature that can be enabled on the director or switch through the Element 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.
FICON management style
The management style that is most useful when attaching to IBM S/390 Enterprise Servers. See
also open systems management style; management style.
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.
FLASH memory
Reusable nonvolatile memory that is organized as segments for writing, and as bytes or words
for reading. FLASH memory is faster than read-only memory, but slower than random access
memory.
Flexport Technology
A Flexport technology switch is delivered at a discount without all the ports enabled. When
additional port capacity is required, the remaining ports are enabled (in eight-port increments)
through purchase of this feature.
FL_Port
See fabric loop port.
FPM card
See fiber port module card.
F_Port
See fabric port.
frame
A variable-length packet of data that is transmitted in frame relay technology.
FRU
See field-replaceable unit.
full-duplex
The capability to simultaneously communicate in both directions over a single connection, with
flow control. Synonymous with bidirectional, contrast with half-duplex.
FX_Port
A port configuration allowing a port to transition operationally to either an F_Port or an
FL_Port. Only the Edge Switch 2/24 supports the configuration of this port type.
