[j-nsp] USB device in J6300 router

[Andrey Vedana Andreoli]

Hello,

We have a J6300 router. This router have three options of system 
storage. The primary boot flash is installed and have been used. The 
removable compact flash and USB are not installed yet. My question is 
about this.

Can I use a USB device as a secondary boot flash? Whats is the problems 
about using the USB device and not the removable compact flash? The USB 
device is much more cheaper.

Thank you.
Andrey
