FESA
FESA. See Fast Ethernet ServerNet adapter (FESA).
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; contractural agreements with suppliers; or national or international standards.
See also customer-replaceable unit (CRU).
file name. A unique name for a file. File names for disk files normally have at least two parts
(the disk name and the file name); an example of a file name on a PC is B:MYFILE. In
the Guardian environment on NonStop S-series systems, disk file names include a disk
volume name, a subvolume name, and a file identifier. An example of a file name on a
NonStop S-series system is $DISK.SUBVOL.MYFILE. For files that are network
accessible, the node name precedes the volume name:
\NODE.$DISK.SUBVOL.MYFILE.
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.
FRU. See also field-replaceable unit (FRU)
full-duplex. Transmission permitted in both directions at the same time over a data
communications line. See also half-duplex
GESA. See Gigabit Ethernet ServerNet adapter (GESA)
Gigabit Ethernet ServerNet adapter (GESA). A single-port ServerNet adapter that
provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™
S-series 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.
Two versions of the GESA are available:
•
3865 GESA-C (T523572): a single-port copper version compliant with the 1000
Base-T standard (802.3ab)
•
3865 GESA-F (T523572): a single-port fiber version compliant with the 1000
Base-SX standard (802..z)
guided procedure. A software tool that assists you in performing complex configuration or
replacement tasks on an HP NonStop S-series server. Guided procedures are
accessible from the Start menu on your system console. Examples include Replace
SEB or MSEB, Configure ServerNet Node, and Replace IOMF.
half-duplex. Transmission permitted in only one direction at a time over a data
communications line. See also full-duplex.
HP NonStop Kernel. The operating system for HP NonStop S-series systems.
