Transceivers
The SANbox 1400 Series switch supports SFP optical transceivers for the Fibre
Channel ports. A transceiver converts electrical signals to and from optical laser
signals to transmit and receive data. Duplex fiber optic cables plug into the
transceivers which then connect to the devices. A Fibre Channel port is capable of
transmitting at 1-Gbps, 2-Gbps, or 4-Gbps; however, the transceiver must be
capable of transmitting at these rates.
The SFP transceivers are hot pluggable. This means that you can remove or
install a transceiver while the switch is operating without harming the switch or the
transceiver. However, communication with the connected device will be
interrupted. Refer to
“Install Transceivers” on page 4-4
for information about
installing and removing SFP optical transceivers.

Port Types
SANbox 1400 Series switches support generic ports (G_Port, GL_Port), fabric
ports (F_Port, FL_Port), and expansion ports (E_Port). Switches come from the
factory with all Fibre Channel ports configured as GL_Ports. Generic, fabric, and
expansion ports function as follows:
A GL_Port self-configures as an FL_Port when connected to a public loop
device, as an F_Port when connected to a single public device, or as an
E_Port when connected to another switch. 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.
A G_Port self-configures as an F_Port when connected to a single public
device, or as an E_Port when connected to another switch.
An FL_Port supports a loop of up to 126 public devices. An FL_Port can also
configure itself during the fabric login process as an F_Port when connected
to a single public device (N_Port).
An F_Port supports a single public device.
An E_Port enables you to expand the fabric by connecting the SANbox 1400
Series switch to another switch. A SANbox 1400 Series switch supports one
inter-switch link. Refer to the
SANbox 1400 Series Switch Management User’s
Guide
for information about defining port types.
