Setup Guide

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 nd 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.

The terminal settings are the same for the MicroUSB-B console port and the RS-232/RJ-45 console port:

• 115200 baud rate

• No parity

• 8 data bits

• 1 stop bit

• No ow control

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.

NOTE: Before starting this procedure, be sure you have a terminal emulation program already installed on your PC. You need to

install the appropriate drivers to support the Micro USB-B port. For assistance, contact www.dell.com/support to download the

drivers.

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. To download the drivers, go to www.dell.com/support.

For assistance, contact Dell EMC Technical Support.

6 Open your terminal software emulation program to access the S4048-ON.

7 Conrm 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 ow control

Mounting the USB storage

The USB storage supports the FAT le system. The USB storage does not automatically mount. To use USB storage, you must rst mount

the device.

1 Create a mount directory for the USB.

ONIE:/ # mkdir /mnt/usb

2 View the xed 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
