Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a terminal-emulation program (such as HyperTerminal) to the Managed Switch console (serial) port.

When using this management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After making this connection, configure the terminal- emulation program to use the following parameters:

•57600 bps

•8 data bits

•No parity

•1 stop bit
