The management panel has a USB port. You may use the port to store
configuration files on flash drives and to restore configuration files to
switches whose settings have been lost or corrupted, or to quickly
configure replacement units. You may also use the port and flash drives to
update the management firmware on the switches.
The port is USB2.0 compatible.
