mode. The switch is shipped in Fabric OS Native mode by default.
v You can enable Access Gateway mode using Fabric OS commands or Web Tools.
v When you enable Access Gateway, you can use the default F_Port-to-N_Port
v Access Gateway simplifies SAN deployment by using N_Port ID Virtualization
v Fabric OS features available to the switch depend on whether the switch is
v In Access Gateway mode, cascading is not available for the SAN48B-5. Refer to
v In Fabric OS Native mode, the switch provides up to eight external Fibre

(NPIV). NPIV provides Fibre Channel switch functions that improve switch
scalability, manageability, and interoperability. For more information on Access
Gateway, refer to the following:
– For a list of F_Ports mapped to N_Ports by default, refer to "Access Gateway
default port mapping" on page 40.
– For general information and details on using Access Gateway, refer to the
Access Gateway Administrator's Guide.
– For specific instructions to prepare the edge fabric before connecting it to
Access Gateway (since Access Gateway relies on NPIV technology for its
connection to the edge fabric), refer to the Access Gateway Administrator's Guide
Note: Access Gateway cannot be connected directly into an array. It requires a
fabric to support NPIV.

Channel ports. These universal and self-configuring ports are capable of
becoming one of the following port types:
– F_Port (fabric enabled)
– FL_Port (fabric loop enabled)
– E_Port (expansion port)
– M_Port (mirror port)
Channel ports. However, these ports are configured as N_Ports, and you cannot
reconfigure these as any other port type.
