An SFP transceiver, like the one shown in 

, converts electrical signals to 

and from optical laser signals to transmit and receive data. SFP transceivers plug 
into the ports; duplex fiber optic cables plug into the transceivers which then 
connect to the devices. A port is capable of transmitting at 1 Gbps or 2 Gbps; 
however, the transceiver must be capable of 2 Gbps for the port to deliver at that 
rate.

The SFP transceivers are hot swappable. This means that you can remove or 
install an SFP transceiver while the switch is operating without harming the switch 
or the transceiver. However, communication with the connected device will be 
interrupted. Refer to 

 for information about 

installing and removing SFP optical transceivers.

SANbox2-16 switches support the following port modes:

„

Generic ports (GL_Port and G_Port)

„

Fabric ports (FL_Port and F_Port)

„

Translated loop ports (TL_Port)

„

Expansion ports (E_Port)

Switches come from the factory with all ports configured as GL_Ports. GL_Ports 
self-configure in the following ways:

„

FL_Port when connected to a loop of public devices

„

F_Port when connected to a single public device. If the device is a single 
device on a loop, the GL_Port will attempt to configure first as an F_Port, 
then if that fails, as an FL_Port.

E_Port when connected to another FC-SW-2 compliant switch
