Sometimes it is necessary to console connect to managed equipment for configuration or troubleshooting purposes. There is nothing better than a raw connection through a tried and true interface.
The PowerConnect 6200 series runs on either a proprietary Marvel OS or VxWorks for the Broadcom based switches.
You will need:
Set the terminal to 8 bit, no parity, 1 stop bit (8N1) @ 9600 bps. Turn Flow Control off and set emulation at VT100+.
Turn the switch on. You should be presented with the boot procedures as the operating system and settings are loaded.
