Features
1
• If the part number is DL-4424-0002, then the SAN I/O Module is configured to run exclusively
in Access Gateway mode. To operate in Full Fabric Switch mode, you must have a Switch
license.
You may also use the CLI licenseshow command to determine whether the module is Dual Function
(Switch/Access Gateway), or single-function Access Gateway. This command displays current
license keys, along with a list of licensed products enabled by these keys. A Dual Function
(Switch/Access Gateway) module should have a “Fabric license” in the command output.
Features
Features available on the SAN I/O Module depend on whether the module is configured in Access
Gateway or Standard Full Fabric Switch mode.
Full Fabric Switch mode
The SAN I/O Module has the following features:
• Up to 8 external autosensing (1, 2, and 4 Gbit/sec) Fibre Channel ports. These are 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)
These ports are capable of Brocade ISL Trunking with appropriate licensing.
• Up to 16 internal backplane F_Ports. Each port is capable of automatic negotiation to the
highest common speed of all connected devices at 4 Gbit/sec.
• Dynamic ports on demand, which allows any port to be activated as needed based on available
licenses.
• Frame filtering that augments the hardware zoning capabilities of the Brocade ASIC, which
implements hardware zoning at the port level of the SAN I/O Module.
• Brocade ASIC expanded capabilities, including World Wide Name (WWN) and device-level
zoning.
• Hardware zoning, implemented by means of a firmware-accessible table per output port.
• Extensive diagnostics and monitoring capabilities.
• Unicast and broadcast data traffic support.
• Up to eight SWL small form-factor pluggable (SFP) optical transceivers.
NOTE
The SAN I/O Module ships with four 4 Gbit/sec SFPs. If you purchase a POD license, you will
receive an additional four SFPs.
• One serial console port on the front panel (RJ45 connector).
• The following light-emitting diodes (LEDs) for each external port.
- One green/amber LED to indicate status for each port.
- One green/amber LED to indicate link speed for each port.
