Micro USB-B console port access
The MicroUSB-B console port is on the I/O side of the switch.
NOTE: The S4048-ON switch uses the Silicon Labs CP2109 USB-B chip. To find the correct USB-B universal
asynchronous receiver-transmitter (UART) driver, see https://www.silabs.com/products/development-tools/software/
usb-to-uart-bridge-vcp-drivers.
When you connect the Micro USB-B port, it becomes the primary connection and, while connected, all messages are sent to the
Micro USB-B port.
1. Power on the PC.
2. Connect the USB-A end of cable into an available USB port on the PC.
3. Connect the MicroUSB-B end of cable into the MicroUSB-B console port on the S4048-ON.
4. Power on the S4048-ON.
5. Install the necessary USB device drivers.
6. Open your terminal software emulation program to access the S4048-ON.
7. Confirm that the terminal settings on your terminal software emulation program are as follows:
● 115200 baud rate
● No parity
● 8 data bits
● 1 stop bit
● No flow control
Mounting the USB storage
The USB storage supports the FAT file system. The USB storage does not automatically mount. To use USB storage, you must
first mount the device.
1. Create a mount directory for the USB.
ONIE:/ # mkdir /mnt/usb
2. View the fixed disks using fdisk.
ONIE:/mnt # fdisk -l
For internal storage:
Disk /dev/sda: 15.8 GB, 15829303296 bytes
255 heads, 63 sectors/track, 1924 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 1925 15458303+ ee EFI GPT
For USB storage:
Disk /dev/sdb: 30.9 GB, 30942946304 bytes
64 heads, 32 sectors/track, 29509 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Device Boot Start End Blocks Id System
3. Mount the device /dev/sdb to the /mnt/usb directory.
ONIE:/ # mount -t vfat /dev/sdb /mnt/usb
NOTE:
The following message displays if the /mnt/usb directory is missing: mount: mounting /dev/sdb
on /mnt/usb failed: No such file or directory.
NOTE: The following message displays if the USB device is not seen: mount: mounting /dev/sdb on /mnt/usb
failed: No such device or address.
