NOTE: If your laptop or PC does not have a DB-9 male connector pin and you
want to connect your laptop or PC directly to a QFX Series device, use a
combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the
device and a USB to DB-9 male adapter. You must provide the USB to DB-9
male adapter.
