Node Name
The unique identifier for a node, communicated during login and port discovery.
Node
A Fibre Channel device that contains an N_Port or NL_Port.
Non-participating Mode
A mode in which an L_Port in a loop is inactive and cannot arbitrate or send frames, but can
retransmit any received transmissions. This mode is entered if there are more than 127 devices
in a loop and an AL_PA cannot be acquired.
See also L_Port, Participating Mode.
Nx_Port
A node port that can operate as either an N_Port or NL_Port.
Open Originator
The L_Port that wins arbitration in an arbitrated loop and sends an OPN ordered set to the
destination port, then enters the Open state.
Open Recipient
The L_Port that receives the OPN ordered set from the open originator, and then enters the
Open state.
Open State
The state in which a port can establish a circuit with another port. A port must be in the Open
state before it can arbitrate.
OPN
Open Primitive Signal.
Ordered Set
A transmission word that uses 8B/10B mapping and begins with the K28.5 character. Ordered
sets occur outside of frames, and include the following items:
• Frame delimiters. Mark frame boundaries and describe frame contents.
• Primitive signals. Indicate events.
• Primitive sequences. Indicate or initiate port states.
Ordered sets are used to differentiate Fibre Channel control information from data frames and
to manage the transport of frames.
