The FC3171 8 Gb SAN Pass-thru can be configured by using either the command line or

QuickTools:

򐂰 Command Line: Access the module by using the console port through the Chassis

Management Module or through the Ethernet port. This method requires a basic

understanding of the CLI commands.

򐂰 QuickTools: Requires a current version of the JRE on your workstation before pointing a

web browser to the module’s IP address. The IP address of the module must be

configured. QuickTools does not require a license, and the code is included.

The pass-through module supports the following standards:

򐂰 Fibre Channel standards:

– C-PH version 4.3

–FC-PH-2

–FC-PH-3
