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.
