Any device connected to Fibre Channel topology is called “node”. 

In the application of this drive, the drive itself and the initiator are the nodes. 

Each node has at least one port to connect other nodes and the port is called 
N_port. 

Especially, in FC-AL, the port is called “NL_Port” where “NL” stands for node 
loop. 

The drive provides two ports and each port is connected to each FC-AL. 

See Figure 1.1. 

Each port provides both Receiver and Transmitter. 

The drive uses electrical wires (differential signal) to receive or transmit the 
information. 

This pair of wires is called a “link”. 

See Figure 1.1. 

The drive Link Rate is selectable either 2 Gbps or 1 Gbps by DEV_CTL signals 
on the Back Plane via SCA-2 Connector. 

It is commonly use for both Ports. 

See Table 1.12. 

Arbitrated loops are defined as “private loop” or “public loop”. 

Private loop has no FL_port (for fabric loop) and all nodes are NL_ports. 

If there is a FL_port which is managing the loop, the loop is called a public. 

This can connect up to 126 active NL_port and one FL_port to the same loop. 

And the NL_ports use arbitration to establish an Initiator-Target connections. 

See Figure 1.1.
