HP NonStop G-Series - Manual (Page 287)

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.
G
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 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.
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.
