Glossary - Fujitsu PRIMEQUEST 480 System Design Manual

ACS (AC Section)
AC power input section
ASIC (Application Specific
Integrated Circuit)
Integrated circuit (IC) designed and
manufactured for specific applications
API (Application Program Interface)
A set of instructions and functions used for
developing operating systems and middleware
BIOS (Basic Input Output System)
Part of the operating system (OS) function.
The BIOS is the system that controls input/
output to devices. For the PRIMEQUEST-
series machine, BIOS is a general term for
PAL, SAL, and EFI.
BMC (Baseboard Management
Controller)
The BMC is a system management controller
that continuously monitors the system for
serious hardware errors and notifies the OS of
such errors.
BMM (BMC Module)
Board on which legacy I/O ports such as BMC,
VGA, USB, and COM ports are mounted
BP (Backplane)
The backplane is connected to SBs, IO_Units,
and other devices. Together with the XAI and
XDI, it constitutes the memory and I/O
interconnect (crossbar).
Business LAN
LAN used to configure a user business system
C122-B001-02EN

Glossary

CLI (Command Line Interface)
This interface with UNIX or DOS allows the
user to enter commands and optional
arguments to communicate with the OS.
COM Port (Communication Port)
RS-232C serial port for PC/AT compatible
machines. A COM port is also called an "RS-
232C port." Most PC/AT compatible machines
each have two COM ports, which are often
used to connect a modem, terminal adapter, or
scanner. Most of these ports use D-Sub 25-pin
or D-Sub 9-pin connectors. A COM port
enables an interface with the OS.
CPCB (Clock and PCI_Box Control
Board)
Board equipped with a system clock oscillator
and a PCI_Box control interface
Crossbar
This concept covers the address crossbar and
data crossbar that transfer data and control the
data transfer between SBs and IO_Units.
Memory and I/O interconnect has the same
meaning as crossbar.
DDR2 (Double Data Rate 2)
Standards for the next generation of memory
that operates at higher speeds and consumes
less power than conventional DDR memory
DIMM (Dual Inline Memory Module)
This compact memory module has pins on both
sides and is mainly used in notebook PCs.
DVD-ROM (Digital Versatile Disc-
Read-Only Memory)
Digital format for high-volume storage of data
on optical disks
GL-1
