The boot loader also provides trap-door access into the system if the operating system has problems serious
enough that it cannot be used. The trap-door operation provides enough access to the system so that if it is
necessary, you can format the flash file system, reinstall the operating system software image by using the
Xmodem Protocol, recover from a lost or forgotten password, and finally restart the operating system.
Before you can assign switch information, make sure that you have connected a PC or terminal to the console
port or a PC to the Ethernet management port, and make sure you have configured the PC or terminal-emulation
software baud rate and character format to match that of the switch console port settings:
• Baud rate default is 9600.
• Data bits default is 8.
If the data bits option is set to 8, set the parity option to none.
Note
• Stop bits default is 2 (minor).
• Parity settings default is none.
Switches Information Assignment
You can assign IP information through the switch setup program, through a DHCP server, or manually.
Use the switch setup program if you want to be prompted for specific IP information. With this program, you
can also configure a hostname and an enable secret password.
It gives you the option of assigning a Telnet password (to provide security during remote management) and
configuring your switch as a command or member switch of a cluster or as a standalone switch.
Use a DHCP server for centralized control and automatic assignment of IP information after the server is
configured.
If you are using DHCP, do not respond to any of the questions in the setup program until the switch
receives the dynamically assigned IP address and reads the configuration file. Note
If you are an experienced user familiar with the switch configuration steps, manually configure the switch.
Otherwise, use the setup program described in the
Boot Process section.
