USB port
The switch has one OHC-compliant USB2.0 port that can upload and download data at a rate up to 480
Mbps. You can use this USB port to access the file system on the Flash of the switch, for example, to
upload or download application and configuration files.
NOTE:
USB devices from different manufacturers vary in compatibilities and drivers. H3C does not guarantee the
correct operation of all USB devices on the switch. If a USB device fails to operate on the switch, replace
it with one from another manufacturer.
