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.
