Fibre Channel
ServerNet adapter
(FCSA)

A ServerNet adapter that transmits data between an HP NonStop™ server and Fibre Channel
storage devices. This ServerNet adapter is installed in an IOAM enclosure.

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. See also

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.

gateway IP
address

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

I/O adapter module (IOAM)

. There are two IOAMs in an

I/O adapter module enclosure

(IOAM enclosure)

, 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

Gigabit

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.
