Transceivers
The SANbox 5000 Series switch supports SFP optical transceivers for the
1/2/4-Gbps ports and XPAK optical transceivers for the 10-Gbps 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 1/2/4-Gbps port is capable of transmitting at 1-Gbps,
2-Gbps, or 4-Gbps; however, the transceiver must also be capable of delivering at
these rates.

The SFP and XPAK 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

Port Types
SANbox 5000 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 1/2/4-Gbps ports configured as GL_Ports. The 10-Gbps ports
come from the factory configured as G_Ports. Generic, fabric, and expansion
ports function as follows:

factory with all 1/2/4-Gbps ports configured as GL_Ports. The 10-Gbps ports
come from the factory configured as G_Ports. Generic, fabric, and expansion
ports function as follows:
A GL_Port self-configures as an FL_Port when connected to a loop device,
as an F_Port when connected to a single 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.

as an E_Port when connected to another switch.
An FL_Port supports a loop of up to 126 devices. An FL_Port can also
configure itself during the fabric login process as an F_Port when connected
to a single device (N_Port).
configure itself during the fabric login process as an F_Port when connected
to a single device (N_Port).
An F_Port supports a single device.
E_Ports enable you to expand the fabric by connecting SANbox 5000 Series
switches. SANbox 5000 Series switches self-discover all inter-switch connections.
