The serial port provides basic communication RS-232 serial-data transfer through a
terminal emulation program (such as Hyperterminal). Because messages from the
power-on self-test (POST) and all initialization information are transmitted through
the serial port, you can use the serial port to log in to the switch and access and
configure the internal switching firmware.
To log in to the switch, complete the following steps:
1. Connect one end of the specifically designed serial cable that comes with your
device into the RS-232 port and connect the other end to the management
station.
For additional information, see
page 21.
2. On the management station, open a console window and make sure that the
serial port is configured with the following settings:
– 9600 baud
– 8 data bits
– No parity
– 1 stop bit
– No flow control
3. When prompted, enter your user name and password.
– When logging in to a switch for the first time, the default switch administrator
user name is USERID, and the default password is PASSW0RD (where the sixth
character is the number zero, not the letter O). The User ID and password
fields are case-sensitive. For security purposes, you will be prompted to
change the administrator password after the first successful login.
– Otherwise, if you have an assigned user account, use your assigned user
name and password.
The serial port is compatible with the standard 16550 Universal Asynchronous
Receiver/Transmitter (UART) protocol. The RS-232 serial port is enabled by default.
