Appendix A Migrating to Generation 3 8-Gbps Fibre Channel Switching Modules
Usage Guidelines
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.
