Glossary ESA™ ESCON™ Ethernet Ethernet hub event code exchange expansion port extended distance feature See Enterprise Systems Architecture. See Enterprise Systems Connection. A widely implemented local area network (LAN) protocol that uses a bus or star topology and serves as the basis for the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standard, which specifies the physical and software layers. A device used to connect the Management Server and the directors it manages. A three-digit number that specifies the exact event that occurred. This code provides information on system failures, such as hardware failures, failure locations, or general information on normal system events. A term that refers to one of the Fibre Channel protocol "building blocks," composed of one or more nonconcurrent sequences. E_Port. Physical interface on a Fibre Channel switch within a fabric, that attaches to an E_Port on another Fibre Channel switch through an interswitch link (ISL) to form a multiswitch fabric. See also fabric loop port; fabric port; generic port; hub port; node loop port; node port; segmented expansion port. XDF. A means to extend the propagation distance of a fiber-optic signal. F fabric fabric address notification Entity that interconnects node ports (N_Ports) and is capable of routing (switching) Fibre Channel frames, using the destination ID information in the Fibre Channel frame header accompanying the frames. A switch is the smallest entity that can function as a complete switched fabric topology. FAN. A message that informs all NL_Ports of the address of the FL_Port. Allows LIP processing to not be disruptive to FC traffic on devices that support FAN. See loop initialization primitive. g-14 EFCM Basic User Manual
