Fast Ethernet
ServerNet adapter
(FESA)
A single-ported ServerNet adapter that supports 100-megabit/second (Mbps) or 10-Mbps Ethernet
data transfer rates on an HP NonStop S-series server.
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: multi-mode fiber-optic (MMF) ServerNet cable and single-mode
fiber-optic (SMF) ServerNet cable.
Fibre Channel
TA data transfer architecture designed for mass storage devices and other peripheral devices
that require very high bandwidth.
Fibre Channel
Arbitrated
Loop(FC-AL)
The American National Standards Institute’s (ANSI) document which specifies arbitrated loop
topology operation.
Fibre Channel disk
module (FCDM)
A unit that holds storage system devices such as disk drives, power supplies, blowers, I/O modules,
transceivers, or EMUs
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.

customer-replaceable unit (CRU)
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.
flash memory
A type of memory that contains essential firmware and nonessential firmware.
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.
G
gateway IP
address
that describes a gateway. A gateway specifies which router will receive communication
destined for addresses in an unknown subnet.
Gigabit Ethernet
4-port ServerNet
adapter (G4SA)
A multiport ServerNet adapter that provides 1000 megabits/second (Mbps) data transfer rates
between HP NonStop™ systems and Ethernet LANs. The G4SA is installed in slots 1, 2, 3, 4,
and 5 of an
, so a total of 10 G4SAs can be installed in an enclosure. The G4SA
is the only LAN adapter supported for the IOAM enclosure. Although the G4SA implements the
Ethernet 4 ServerNet adapter (E4SA)
,
Fast Ethernet ServerNet adapter (FESA)
, and the
Ethernet ServerNet adapter (GESA)
functions, it cannot be installed in an HP NonStop S-series
enclosure.
Gigabit Ethernet
ServerNet adapter
(GESA)
A single-port ServerNet adapter that provides 1000 megabits/second (Mbps) data transfer rates
between HP NonStop™ systems and Ethernet LANs. A GESA can be directly installed in slots 51
through 54 of an I/O enclosure and slots 53 and 54 of a processor enclosure.
globally unique ID
(GUID)
A unique, read-only number stored in nonvolatile memory (SEEPROM) on a ServerNet II Switch
at the time of manufacture. The GUID also appears on the bar code label. This number can be
used programmatically to identify the switch.
group
Part of the group, module, slot naming convention for uniquely identifying the logical location of
a component within a system. A group is a subset of a system and contains one or more modules.
A group does not necessarily correspond to a single physical object, such as an enclosure. For
example, an HP NonStop S-series processor enclosure typically includes only one group number,
but a modular cabinet can contain several enclosures that each might belong to different groups.

guided procedure
A software tool that assists you in performing complex configuration or replacement tasks on an
NonStop server. OSM guided procedures are launched through actions in the OSM Service
Connection.
