Usage Guidelines Appendix A Migrating to Generation 3 8-Gbps Fibre Channel Switching Modules Send documentation comments to [email protected]. The MDS 9509 Director and the MDS 9506 Director also support the Generation 3 8-Gbps modules. The switches require Supervisor-2 modules and Cisco MDS NX-OS 4.1(1b) to support the Generation 3 8-Gbps modules. Note To upgrade to NX-OS Release 4.1(1b) from SAN-OS Release 3.2(3a) or earlier, first upgrade to SAN-OS Release 3.3(1x) and then upgrade to NX-OS Release 4.1(1b). Usage Guidelines In preparation for using the MDS 9513 Fabric 2 module and the Generation 3 8-Gbps modules in an MDS 9513 Director, be aware of the following usage guidelines: • Cisco SAN-OS release 3.x supports the MDS 9513 Fabric 2 module. • Until you upgrade to Cisco NX-OS 4.1(1b) and reload the switch, a MDS 9513 Fabric 2 module functions like a MDS 9513 Fabric 1 module. • You cannot use any Generation 3 8-Gbps module in a MDS 9513 Director, MDS 9509 Director, or MDS 9506 Director until you upgrade to NX-OS 4.1(1b). • Supervisor-2 modules are required for the MDS 9509 Director and the MDS 9506 Director to support any Generation 3 8-Gbps module. • You must do the following to enable the increased bandwidth capabilities of the MDS 9513 Fabric 2 modules: - Upgrade from Cisco SAN-OS 3.x to NX-OS release 4.1(1b). - Migrate the existing MDS 9513 Fabric 1 modules in the MDS 9513 chassis to MDS 9513 Fabric 2 modules. - Reload the switch to enable the increased bandwidth. • If you install just one MDS 9513 Fabric 2 module, the active slot bandwidth of MDS 9513 Director is 96-Gbps full duplex. • Once you upgrade to Cisco NX-OS 4.1(1b) and reload the switch, a downgrade to Cisco SAN-OS release 3.x will be disruptive. Following the downgrade, the Generation 3 8-Gbps modules in the switch will not power up. Table A-1 lists the types of Generation 3 modules that the MDS 9513 Director supports.
