When a chassis is rRMAed, the spare chassis will have a default config

When a fresh QFX is powered on, it will have a default configuration that may not be compatible with the configurations the customer wants to have.

So it is recommended to delete all factory default config before provisioning new box. for eg.

[edit interfaces et-0/0/48]

-   unit 0 {

-       family inet {

-           dhcp {

-               vendor-id Juniper-qfx10002-72q;

-           }

-       }

-   }



Use 'delete' keyword to delete factory configs before provisioning a new box. This will delete all default config. Post this users can configure the chassis per their requirements.
