Appendix D Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
When POST completes successfully, the System LED remains green. The RPS LED remains green for
some time and then returns to its operating status. The other LEDs turn off and return to their operating
status.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
After you have powered all the switches in the stack, a switch is elected as the stack master. The master
LED is green on the stack master switch.
If you started the terminal emulation program before you powered on your switch, the PC or terminal
displays the bootloader sequence. You need to press Enter to display the setup program prompt.
Entering the Initial Configuration Information
To set up the switch, you need to complete the setup program, which runs automatically after the switch
is powered up. You must assign an IP address and other configuration information necessary for the
switch to communicate with the local routers and the Internet. This information is also required if you
plan to use the Network Assistant to configure and manage the switch.
IP Settings
You will need this information from your network administrator before you complete the setup program:
• Switch IP address
• Subnet mask (IP netmask)
• Default gateway (router)
• Enable secret password
• Enable password
• Telnet password
Completing the Setup Program
Note If your switches are stacked and there are multiple console connections to individual switches in the
stack, the initial setup dialog appears in the first console where the user presses Enter.
Follow these steps to complete the setup program and to create an initial configuration for the switch:
Step 1 Enter Yes at the following two prompts.
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
