Configuration Guide Configuring USB
The Ruijie General Operating System (RGOS) is applicable only to devices (generally common USB flash drives) that
support standard Small Computer System Interface (SCSI) commands. Other devices, such as the USB flash drive
embedded in the USB network interface card (NIC) and USB flash drive with the virtual CD-ROM drive, cannot be used
in the RGOS. Some devices are configured with the function of converting a USB port to the serial port.
The USB supports only the FAT file system. Other file systems on the USB must be formatted to the FAT file system on
a PC before the USB can be used on a device.
The RGOS supports the hub. When a USB flash drive is inserted to a port on a hub, the access path becomes different.
If the USB flash drive is inserted to a USB port on a device, the access path is usbX:/, where X indicates the device ID.
You can run the show usb command to display this path. If the USB flash drive is inserted to a USB port through a hub,
the access path is usbX-Y:/, where X indicates the device ID, and Y indicates the hub port ID. For example, usb0-3:/
indicates port 3 on the hub that is connected to USB port 0 on the device.
Configuration Steps
Identifying a USB
A USB can be directly inserted to the USB slot without a CLI operation.
Using a USB
Perform the following operations to copy files from a USB to the flash:
Run the cd command to enter the partition of the USB.
Run the copy command to copy files on the USB to the flash on the device.
Run the dir command to check whether the files are copied to the device.
If the USB has multiple partitions, you can access only the first FAT partition on the device.
The path of the USB does not contain any upper-level directory. After running the cd usbX:\ command to access a USB,
you can run the cd flash:\ command to return to the flash file system.
Verification
Run the show usb command to display information about the USB inserted to the device.
Configuration Example
Using a USB Flash Drive
Insert the USB flash drive into the USB slot of the device.
Run the show usb command on the device console.
Copy the config.txt file from the USB flash drive to the flash on the device.
