Note Information in this chapter about configuring IP addresses and DHCP is specific to IP Version 4 (IPv4).

To start your switch, you need to follow the procedures in the hardware in stallation guide about install ing

and powering on the switch, and setting up the initial configuration (IP address, subnet mask, default

gateway, secret and Telnet passwords, and so forth) of the switch.

The normal boot process involves the operation of the boot loader software, whic h perfo rm s the se

functions:

•Performs low-level CPU initialization. It initializes the CPU registers, which control where physical

memory is mapped, its quantity, its speed, and so forth.

•Performs power-on self-test (POST) for the CPU subsystem. It tests the CPU DRAM and the portion

of the flash device that makes up the flash file system.
