ASAN I/O Module specifications
This appendix provides product specifications and regulatory compliance as a handy reference.
Access Gateway Mode default port mapping
The 4424 SAN I/O Module can contain 24 total ports. Of these, F_Ports are ports 1-16 and N_Ports
are ports 0 and 17-23.
In Access Gateway mode, the SAN I/O Module F_Ports are mapped to N_Ports. This following lists
the factory-default F_Port to N_Port mapping for Access Gateway mode. Since the SAN I/O Module
is shipped with Dynamic Ports on Demand (DPOD) enabled, any out of the 24 ports can be
enabled. Therefore this mapping applies for 12 active ports or, if POD licensing is enabled, for 24
ports. For more information on changing port mapping and managing ports in Access Gateway
Mode, refer to the Access Gateway Administrator’s Guide.
