CAUTION: Ensure that any equipment attached to the serial port can support the required 115200 baud rate.
NOTE: Before starting this procedure, ensure your PC has a 9-pin serial port. You must have a terminal emulation program
already installed and running on your PC.
NOTE: If your PC’s serial port cannot accept a female DB-9 connector, use a DB-9 male-to-male adaptor.
1 Install the provided RJ-45 connector side of the provided cable into the S4112-ON Series console port.
2 Install the DB-9 female side of the provided copper cable into your PC’s serial port. Or install the DB-9 cable into other data terminal
equipment (DTE) server hardware that you intend to use.
3 Keep the default terminal settings on the console as follows:
• 115200 baud rate
• No parity
• 8 data bits
• 1 stop bit
• No ow control
USB-B console port access
The USB-B console port is on the I/O side of the switch.
NOTE
: The S4112-ON Series switches use 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 serial 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 USB-B port, it becomes the primary connection and, while connected, all messages are sent to the USB-B port.
