Hi,
You’re able to run both Fabric 1 and Fabric 2 modules together in the same chassis, but there are some significant limitations. From the Upgrading Fabric 1 Modules with Fabric 2 Modules section of the Cisco Nexus 7000 Series Hardware Installation and Reference Guide.
"If you are running Cisco NX-OS 6.0(x) or a later release, you can upgrade all of the Fabric 1 modules with Fabric 2 modules in a Cisco Nexus 7010 or 7018 switch (the Cisco Nexus 7009 uses only Fabric 2 modules). You can upgrade the modules during operations if you replace each within a couple of minutes so that the switch can maintain its designed airflow. The upgrade process is non disruptive to switch operations if there is at least one fabric module installed and operating in the switch while you upgrade another fabric module.
When upgrading fabric modules, you must replace all of the Fabric 1 modules in the switch with Fabric 2 modules within 12 hours or you will see a syslog message that reminds you to complete the upgrade.
Note If you power up a switch that has both types of fabric modules installed, only the Fabric 2 modules power up. If you need the Fabric 1 modules to power up, you must first power off all of the Fabric 2 modules (see the “Shutting Down a Fabric Module” section) before the Fabric 1 modules can power up."
The above limitations would suggest this is supported from the perspective of allowing a "hitless" migration, but should not be used as a permanent solution.
I’ve not personally used Fabric-2 modules with Supervisor-1, but I can’t find any documentation stating that Fabric-2 modules will only work with Supervisor-2/2E.
Regards
