Connect the serial console interface (an RJ–45 jack) to a PC or terminal to monitor and configure the switch. The port uses a RJ–45 connector that operates as data terminal equipment (DTE). Some switches also provide a USB port or micro USB port for serial console interface connectivity. See your hardware documentation for available ports.
The default communication protocol settings for the console port are:
Baud rate is 115200
8 data bits
1 stop bit
No parity
No flow control
To use the console port, you need a terminal or teletypewriter (TTY)-compatible terminal, or a portable computer with a serial port and terminal-emulation software.
