Managing The System Hardware; Replacing Components - Cisco Nexus 7000 Hardware Installation And Reference Manual

Managing the System Hardware

If you are replacing Fabric 1 modules with Fabric 2 modules (Cisco Nexus 7010 and 7018 models only),
you must replace all of the Fabric 1 modules with Fabric 2 modules or the Fabric 2 modules will perform
like Fabric 1 modules. If you power up a switch with both Fabric 1 and Fabric 2 modules installed, only
the Fabric 2 modules will power up.
The Cisco NX-OS software may require 8 GB of memory, depending on the software version you use
Note
and the software features that you enable. If your switch has Supervisor 1 modules with only 4 GB of
memory, then you might need to upgrade the modules to 8 GB of memory by using the 8 GB supervisor
upgrade kit (N7K-SUP1-8GBUPG=). This upgrade is not needed for switches that have at least 8 GB of
memory (which includes Supervisor 1 modules with 8 GB and all Supervisor 2 and Supervisor 2E
modules). To verify the amount of memory installed in the supervisor modules or to upgrade the
memory, see the
Managing the System Hardware
