The following terms and acronyms are found in this manual.
3U
A unit of measurement of the height of a rack mount device equal to approximately 1.75
inches. A 3U board is 5.25 inches in height.
Bit Banging
A software technique that emulates a serial interface standard (I
rapidly changing a single output bit, in software, at the appropriate time.
BMC
Baseboard Management Controller.
cPCI
Compact PCI system is a 3U (or 6U) Eurocard‐based industrial computer, where all boards are
connected via a passive PCI backplane. Originally designed to support the PCI signaling
protocol (hence the name ʹCompactPCIʹ), CompactPCI has grown to include a variety of
technologies on a 3U and 6U form factor.
ECC
Error Correction Code.
EEPROM
Electrically Erasable Programmable Read‐Only Memory.
ESD
Electro‐Static Discharge.
F-Link
An ʺFʺ (fully associated) link connects two signaling end points (for example, SSPs and
SCPs). ʺFʺ links are not usually used in networks with STPs. In networks without STPs, ʺFʺ
links directly connect signaling points
GbE
Gigabit Ethernet.
GND
Ground.
IP
Internet Protocol.
IPMC
Intelligent Platform Management Controller.
IPMI
Intelligent Platform Management Interface.
Layer 2
Layer 2 refers to the Data Link layer of the Open Systems Interconnection (OSI)
communications model. The Data Link layer is concerned with moving data across the
physical links in the network.
Layer 3
Layer 3 refers to the Network layer of the Open Systems Interconnection (OSI)
communications model. The Network layer is concerned with knowing the address of the
neighboring nodes in the network, selecting routes and quality of service, and forwarding as
appropriate.
LED
Light Emitting Diode.
Mbps
Megabits per second.
MDI
Media Direct Interface.
MHz
MegaHertz.
OEM
Original Equipment Manufacturer.
PCI
Peripheral Component Interconnect is an I/O bus (peripheral bus). The PCI bus provides a
shared data path between the CPU and peripheral controllers, such as network, display, and
storage devices.
