Chapter 1 Overview
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.
Note
The Cisco NX-OS software may require 8 GB of memory, depending on the software version you use
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
“Upgrading Memory for Supervisor 1 Modules” section on page 10-29 .
Managing the System Hardware
After the Cisco Nexus 7000 Series system is installed and operating, you can use the Cisco NX-OS
operating system to manage the system hardware. These management functions include displaying
system and module information, setting the power supply modes, and managing module functions. For
more information about these functions, see
Chapter 8, “Managing the Switch Hardware.”
Replacing Components
While the Cisco Nexus 7000 Series system is operational, you can replace any one of the following
components if they are redundant:
• Power supply
•
Supervisor module
• Fabric module (Cisco Nexus 7009, 7010, and 7018 models only)
•
I/O modules
•
Fan trays
For detailed information on replacing these components, see Chapter 10, “Installing or Replacing
Components.”
