Translated Loop Port
A TL_Port supports a loop of up 124 private target devices with the ability to
communicate with up to 63 “off-loop” public devices. Private loop Initiator devices
are not supported on the TL_Port. The TL_Port acts as a proxy for the off-loop
device translating private frames into and from public frames. The set of off-loop
devices are maintained in the TL_Port’s translation entries list. The switch
firmware automatically creates an entry in the translation entries list for each off-
loop initiator device that attempts to establish communication. Soft or VPF zoning
can be used to limit the number of potential initiators to 63. Zone membership
must be done by worldwide name, or domain ID and port ID. TL_Ports connect to
devices that conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-
PLDA) standard. Devices connected to TL_Ports are registered with the Name
Server.

Expansion Port
E_Ports enable you to expand the fabric by connecting SANbox2-64 switches with
other FC-SW-2 compliant switches. SANbox2-64 switches self-discover all inter-
switch connections. Refer to ”Multiple Chassis Fabrics” on page 3-4 for more
information about multiple chassis fabrics.
