6
DFT Design for Testability.
DQ Descriptor Queue.
DMTF Distributed Management Task Force standard body.
DW Double word (4 bytes).
EEE Energy Efficient Ethernet - IEEE802.3az standard
EEPROM
Electrically Erasable Programmable Memory. A non-volatile memory located on the LAN
controller that is directly accessible from the host.
EOP End of Packet.
FC Flow Control.
FCS Frame Check Sequence.
Firmware (FW)
Embedded code on the LAN controller that is responsible for the implementation of the NC-
SI protocol and pass through functionality.
Host Interface
RAM on the LAN controller that is shared between the firmware and the host. RAM is used to
pass commands from the host to firmware and responses from the firmware to the host.
HPC High - Performance Computing.
IPC Inter Processor Communication.
IPG Inter Packet Gap.
IPMI Intelligent Platform Management Interface specification
LAN (auxiliary Power-Up)
The event of connecting the LAN controller to a power source (occurs even before system
power-up).
LLDP
Link Layer Discovery Protocol defined in IEEE802.1AB used by IEEE802.3az (EEE) for system
wake time negotiation.
LOM LAN on Motherboard.
LPI Low Power Idle - Low power state of Ethernet link as defined in IEEE802.3az.
