Plan a Virtual Chassis Fabric Deployment
A Virtual Chassis Fabric (VCF) architecture supports up to 20 interconnected devices that are managed as a logical single device. Supported platforms vary depending on the QFX Series switch chosen for the spine. See Understanding Virtual Chassis Fabric Components and Virtual Chassis Fabric Hardware Overview for supported configurations. Although the architecture has a powerful auto-provisioning option, which allows you to plug and play the devices, careful planning of the deployment can avoid unexpected results.
For example, if you perform any configuration level commands on one of the devices (including assigning IP addresses or host names) you no longer can use auto-provisioning.
Use the following checklist to plan your deployment:

Item or Task
For More Information
Determine the number of devices in the VCF and the role of each device.
Note: A VCF is not constrained to a single building; the limits for the optic cable are the only consideration.
Evaluate the provisioning options and determine the configuration method that applies to your deployment.
Measure the distance between external power sources and switch installation site.
Calculate the power consumption and requirements.
|Rack or Cabinet|
Verify that your rack or cabinet meets the minimum requirements for the installation of the switch.
Plan rack or cabinet location, including required space clearances.
Secure the rack or cabinet to the floor and building structure.
Acquire cables and connectors:
Plan the cable routing and management.
