I've been installing Cisco 2901 routers. The router comes with a small plastic tab with self-adhesive backing part # 700-37332-01-A0. I'm curious what that part is for.
The only thing that's "adhesive" in every R & S appliances are the black rubber "tabs". These are to be stuck on the bottom of the routers in every corner. Helps minimize vibrations if you don't want to rack-mount them.
