You may use Switch management to configure any or all ports on the SANbox-16 
chassis as Translated Loop ports (TL_Ports). TL_Ports connect to devices which 
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA) 
standard. Each TL_Port allows connectivity between the Private Loop devices on 
the loop and “off-loop” devices (devices not connected to that particular TL_Port) 
such as Public devices connected to F and FL_Ports and private devices on other 
TL_Port loops. This connectivity is achieved by having a translation function at 
each TL_Port which translates Private frames to Public frames and vice versa.

 shows possible Fabric topologies with both public and Private SCSI 

devices. In this figure, the TL_Ports are ports with Translation Mode functions. 
The following three scenarios are supported by TL_Ports:

•

Server 1 to ST1 (Public Initiator to/from Private Target)

•

Server 2 to ST2 (Private Initiator to/from Public Target)

•

Server 3 to ST3 (Private Initiator through fabric to/from Private Target on 
different loop)
