What is chassisFNB?
This read-only enumerated integer reports whether the FNB, the internal Flexible Network Bus backplane, is present(2) or absent(1) in this chassis. An administrator checks this to confirm whether the chassis has the internal backplane bus needed for inter-board communication, useful when troubleshooting boards that can't reach each other across a chassis. For example, if newly installed boards can't communicate with each other, the admin first checks this object to confirm the FNB backplane itself is present.
