MicroUSB-B console port access
The MicroUSB-B console port is on the PSU side of the switch.
NOTE:
The S5148F-ON switch uses the Silicon Labs CP2109 USB-B chip. To find the correct USB-B universal
asynchronous receiver-transmitter (UART) driver, see
usb-to-uart-bridge-vcp-drivers.
When you connect the microUSB-B port, it becomes the primary connection and, while connected, all messages are sent to the
microUSB-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 switch.
4. Power on the switch.
5. Install the necessary USB device drivers.
6. Open your terminal software emulation program to access the switch.
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
USB storage mount
USB storage does not automatically mount. USB storage supports the FAT file system. To use USB storage, first mount the
device using the following steps:
1. Create a mount directory for the USB storage.
ONIE:/ # mkdir /mnt/usb
2. View the fixed disks using the fdisk command.
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
/dev/sda1
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
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.
