Changing from Fabric Switch mode to Access Gateway mode 2
Tie wraps are not recommended for optical cables because they are easily overtightened.
a. Orient a cable connector so that the key (the ridge on one side of connector) aligns with
the slot in the transceiver.
b. Insert the cable into the transceiver until the latching mechanism clicks. For instructions
specific to cable type, refer to the cable manufacturer’s documentation.
c. Repeat for the remaining transceivers as required.
6. Check the LEDs to verify that all components are functional.
For information about LED patterns, see the “Interpreting LED activity” on page22.
7. Verify the correct operation of the SAN I/O Module by typing the switchShow command from
the workstation.
This command provides information about SAN I/O Module and port status.
8. Verify the correct operation of the SAN I/O Module in the fabric by typing the fabricShow CLI
command from the workstation.
9. Back up the SAN I/O Module configuration to an FTP server by typing the configUpload
command and following the prompts.
This command uploads the SAN I/O Module configuration to the server, making it available for
downloading to a replacement SAN I/O Module if necessary. Brocade recommends backing up
the configuration on a regular basis to ensure that a complete configuration is available for
downloading to a replacement SAN I/O Module.
For specific instructions about how to back up the configuration, see the Fabric OS
Administrator’s Guide. The switchShow, fabricShow, and configUpload commands are
described in detail in the Fabric OS Command Reference Manual.
Changing from Fabric Switch mode to Access Gateway mode
If your SAN I/O Module can run in Dual Function mode and is currently configured in Standard Full
Fabric Switch mode you can enable Access Gateway mode using the following instructions. You can
log into the SAN I/O Module and enable Access Gateway mode using either Web Tools or the SAN
I/O Module command line interface (CLI).

Notes

•The module ships from the factory in either Access Gateway or Dual Function mode. In Dual
Function mode, you can configure the module for either Access Gateway Mode or Full Fabric
Switch mode without an additional license. The module is enabled for Full Fabric Switch mode
as the default. If the module comes configured in Access Gateway mode, you will need an
upgrade license to change to Dual Function mode.
•Enabling Access Gateway mode is a disruptive process because the switch is disabled and
rebooted.Once you enable the SAN I/O Module in Access Gateway mode, only a limited subset
of Fabric OS commands are available and all fabric-related service requests are forwarded to
the fabric switches. See the Access Gateway Administrator’s Guide for more information.
•When you enable Access Gateway mode some fabric information is erased, such as the zone
and security databases. To recover the information save the switch configuration before
enabling Access Gateway mode.
