Installation Guide
FRB: Fault Resilient Boot. A server management
feature. FRB attempts to boot a system using the
alternate processor or DIMM.
FRU: Field Replaceable Unit. A component that is
replaced or added by Customer Service Engineers
as a single entity.
FSS: FAME Scalability Switch. Each CSS Module
is equipped with 2 Scalability Port Switches
providing high speed bi–directional links between
server components. See SPS.
FTP: File Transfer Protocol. A standard Internet
protocol: the simplest way of exchanging files
between computers on the Internet. FTP is an
application protocol that uses Internet TCP/IP
protocols. FTP is commonly used to transfer Web
page files from their creator to the computer that
acts as their server for everyone on the Internet. It
is also commonly used to download programs and
other files from other servers.
FWH: FirmWare Hub.
G
GB: GigaByte: 1,073,741,824 bytes. See Byte.
GUI: Graphical User Interface.
H
HA: High Availability. Refers to a system or
component that is continuously operational for a
desirably long length of time.
HA CMP: High Availability Clustered
MultiProcessing.
Hard Disk Drive: HDD. See Disk Drive.
Hardware: The physical parts of a system,
including the keyboard, monitor, disk drives, cables
and circuit cards.
Hardware Monitor: A PAM feature used to
supervise server operation.
Hot Plug: A method used to insert or remove
system components during system operation.
Hot Swap: A method used to insert or remove
system components during system operation.
HBA: Host Bus Adapter.
HDD: Hard Disk Drive. See Disk Drive.
History File: A file in which the History Manager
logs informative messages or error messages
relating to system activity. Messages are sent from
source components to target components.
History Manager: The component running on the
PAP Windows operating system that logs
messages to history files.
HPC: High Performance Computing.
Hot plugging: The operation of adding a
component without interrupting system activity.
Hot swapping: The operation of removing and
replacing a faulty component without interrupting
system activity.
HTTP: HyperText Transfer Protocol. In the World
Wide Web, a protocol that facilitates the transfer of
hypertext–based files between local and remote
systems.
HW Identifier: Number (0 – F) used to identify
Cellblock components. This number is identical to
PMB code–wheel position.
I
I2C: Intra Integrated Circuit. The I2C (Inter–IC) bus
is a bi–directional two–wire serial bus that provides
a communication link between integrated circuits
(ICs).
The I2C bus supports 7–bit and 10–bit address
space devices and devices that operate under
different voltages.
IA64: is a 64–bit Intel processor Architecture based
on Explicitly Parallel Instruction Computing (EPIC).
The Itanium processor is the first in the Intel line of
IA–64 processors.
IB: Infini Band.
IC: Integrated Circuit. An electronic device that
contains miniaturized circuitry. See Chip.
ICH4: I/O Control Hub.
ICMB: Intelligent Chassis Management Bus.
ID: A number which uniquely identifies a device on
a bus.
IDE: Integrated Drive Electronics. A type of hard
disk drive with the control circuitry located inside
the disk drive rather than on a drive controller card.
Identity: a PAM Domain management logical
resource. This resource contains context
information related to the Customer activity running
in a domain. The most visible attribute of this
resource is the name that the Customer gives to
the activity. For each domain created, the Domain
management feature allows the operator to define
a new activity or choose an activity from the list of
existing activities. See Domain.
