Console Port Booting 6855 Series Switches Console Port The console port, located on the chassis front panel, provides a console connection to the switch and is required when logging into the switch for the first time. By default, this RJ-45 connector provides a DTE console connection. Serial Connection Default Settings The factory default settings for the serial connection are as follows: baud rate parity data bits (word size) stop bits flow control 9600 none 8 1 none Modifying the Serial Connection Settings The switch's serial connection defaults are listed above. If you wish to modify the default serial connection settings (i.e., baud rate, parity, data bits, and stop bits), refer to the following steps: Note. You must be connected to the switch via the console port before attempting to change serial connection settings. Otherwise, an error message will display. For switches in a stacked configuration, all changes must be configured before the switches are cabled together. In other words, you must configure these settings when each switch is operating as a stand-alone unit. 1 Enter the modify boot parameters command at the CLI prompt. The boot prompt displays: Boot > 2 To change the baud rate, enter boot serialbaudrate, followed by the desired baud rate value. Options include 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 76800, and 115200. For example: Boot > boot serialbaudrate 19200 Note. Setting the console port to speeds above 9600 baud can cause problems with Zmodem uploads. 3 To change the parity value, enter boot serialparity, followed by the desired parity value. Options include none (default), even, and odd. For example: Boot > boot serialparity even 4 To change the data bits (i.e., word size) value, enter boot serialwordsize, followed by the number of data bits. Options include 7 and 8 (default). For example: Boot > boot serialwordsize 7 page 5-2 OmniSwitch 6855 Series Hardware Users Guide September 2011
