Instruction Manual

K28.5 A special 10-bit character that indicates the b eginning of a
transmission word that performs FC control and signaling
functions. The first seven bits are the common pattern.
kernel flash F lash (temporary) memory connected to the peripheral bus of
the processor and visible within the processor’s memory space.
Also called a user flash.
L_Port Loop port. A node port (NL_Port) or fabric port (FL_Port) that
has arbitrated loo p capabilities. An L_Port can be in one of
two modes:
• Fabric mode: Connected to a port that is not loop capable
and is using fabric protocol.
• Loop mode: In an arbitrated loop and using loop protocol.
An L_Port in loop mode can also be in participating mode
or non-participating mode.
See also non-par ticipating mode.
latency Thetimerequiredtotransmitaframefromthetimeitissent
until it arrives. Tog ether, latency and bandwidth define the
speed and capacity of a link or system.
link With respect to FC, a physical connection between two ports,
consisting of both transmit and receive fibers.
link services A protocol for link-related actions.
LIP Loop initialization primitive. The signal that begins initialization
in a loop. It indicates either loop failure or the resetting of
anode.
LM_TOV Loop master time-out value. The minimum time that the loop
master waits for a loop initialization sequence to return.
loop failure Loss of signal within a loop for any period of time; loss of
synchronization for longer than the time-out value.
Loop_ID A hexadecimal value representing one of the 127 possible
AL_PAvaluesinanarbitratedloop.See also AL_PA.
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 no de. See also AL_PA.
LPSM Loop port state machine. The logical entity that performs
arbitrated loop protocols and defines the behavior of L_Ports
when they require acc ess to an arbitrated loop. See also L_Port .
