The Attachment Unit Interface (AUI) is a physical and logical interface defined in the IEEE 802.3 standard for 10BASE5 Ethernet [1] and the earlier DIX standard. The physical interface consists of a 15-pin D-subminiature connector that links an Ethernet node's physical signaling to the Medium Attachment Unit (MAU), [ 2 ] sometimes referred to ...
Reduced Pin eXtended Attachment Unit Interface (RXAUI) is a proprietary modification created by Marvell [2] and Dune Networks [3] (later acquired by Broadcom [4]) aimed to increase the port density by decreasing the interface pin count. The four lanes of the standard XAUI running at 3.125 Gbit/s are replaced by two lanes at 6.25 Gbit/s.
AAUI signals have the same description, function, and electrical requirements as the Attachment Unit Interface (AUI) signals of the same name, as detailed in IEEE 802.3-1990 CSMA/CD Standard, section 7, [4] with the exception that most hosts provide only 5 volts of power rather than the 12 volts required for most AUI transceivers.
A Medium Attachment Unit (MAU) is a transceiver which converts signals on an Ethernet cable to and from Attachment Unit Interface (AUI) signals. On original 10BASE5 (thicknet) Ethernet equipment, the MAU was typically clamped to the Ethernet wire via a vampire tap and connected by a multi-wire cable to the computer via a DA-15 port, which was ...
An Ethernet network interface controller (NIC) may include the 10BASE2 transceivers and thus directly provide a 10BASE2 BNC connector (that the T-connector plugs into), or it may offer an AUI connector that external transceivers (see Medium Attachment Unit) can connect to. These can be transceivers for 10BASE2, but also for 10BASE5 or 10BASE-T.

3.5" Floppy disk drive by Alps Electric with FRU number A field-replaceable unit (FRU) [1] is a printed circuit board, part, or assembly that can be quickly and easily removed from a computer or other piece of electronic equipment, and replaced by the user or a technician without having to send the entire product or system to a repair facility.
The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market.
