Do not use the handles on the side of the chassis to lift the Cisco Nexus 7009, 7010, or 7018 chassis or a fully
loaded Cisco Nexus 7004 chassis (you can use these handles to lift a Cisco Nexus 7004 chassis if you remove
the power supplies so that the chassis weighs less than 120 pounds [52 kg]). For the Cisco Nexus 7009, 7010,
and 7018, use these handles only for adjusting the position of the chassis while the chassis rests on a platform
or bottom-support rails.
Caution
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 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 10-31 .
Note
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.”
