IMPORTANT: · Due to compatibility and driver differences among USB devices of different manufacturers, H3C does not guarantee that USB devices from all manufacturers will function normally on this series of switches. If a USB device is not functioning properly, it is not due to a switch fault. Try using a USB device from a different manufacturer. · The USB port on the switch is designed to output current strictly in accordance with the USB 2.0 standard. Use USB storage devices that fully comply with USB 2.0 standards. If the USB storage device you use does not fully comply with the USB 2.0 standard, the USB port of this switch might fail to recognize the USB device. |
