Usb Port; Qsfp28 Port - H3C S6850 Series Manual

USB port

The switch has one OHCI-compliant USB 2.0 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.
The USB port supplies power as per USB 2.0 specifications. Use only USB 2.0-compliant USB
devices for the USB port. The port might not identity USB devices that are not compliant with USB
2.0.
NOTE:
USB devices from different vendors vary in compatibilities and drivers. H3C does not guarantee correct
operation of USB devices from other vendors on the switch. If a USB device fails to operate on the switch,
replace it with one from another vendor.
