Dell Networking N1500/N2000/N3000/N4000 Series Switches
When available, a USB flash drive can be used to configure, upgrade and
provide consistency to a switching network. A USB flash drive can be plugged
in sequentially to a set of routers/switches to upgrade to newer software
versions without depending on the network to upgrade the switches with new
firmware. New switches can be preloaded with configuration prior to
deployment.
The USB Configuration Port provides access to an optional secondary storage
capability to the switch. A USB flash drive can be used to store and deploy
configurations and images from USB flash drive to the switch. A USB flash
drive can be used easily to move and copy configuration and image files from
one switch to other. Files from the switch can be copied to a USB flash device
and can be used to deploy on other switches in the network.
