Loop Initialization
The logical procedure used by an L_Port to discover its environment. Can be used to assign AL_PA
addresses, detect loop failure, or reset a node.
Loop_ID
A hex value representing one of the 127 possible AL_PA values in an arbitrated loop.
Looplet
A set of devices connected in a loop to a port that is a member of another loop.
LPSM
Loop Port State Machine. The logical entity that performs arbitrated loop protocols and defines the
behavior of L_Ports when they require access to an arbitrated loop.
LWL
Long Wavelength. A type of fiber optic cabling that is based on 1300-mm lasers and supports link
speeds of 1.0625 Gbps. May also refer to the type of GBIC or SFP.
