link incident.
link
Physical connection between two devices on a switched fabric.
link incident
Interruption to link due to loss of light or other causes.
load balancing
Ability to evenly distribute traffic over multiple interswitch links within a fabric. Load
balancing on directors takes place automatically.
logical unit number
Also known as LUN. In Fibre Channel addressing, a logical unit number is a number
assigned to a storage device which, in combination with the storage device

world-wide name, represents a unique identifier for a logical device on a storage area
network.
loopback plug
In a fiber optic environment, a type of duplex connector used to wrap the optical output
signal of a device directly to the optical input.
loopback test
Test that checks attachment or control unit circuitry, without checking the mechanism
itself, by returning the output of the mechanism as input.
