Chapter 12: Initial Switch Configuration
Switch Bootup Process
For your initial access to the switch, make sure you plug the rollover cable into the
switch's console port and the other end into the COM port of your computer. Start
up a terminal emulation program such as HyperTerminal, Tera Term, or PuTTY to
view the command-line interface (CLI) output of the switch. When power is applied
to the 2960, the switch will begin its bootup process. Flash is first validated, and
then the IOS is found, uncompressed, and loaded.
POST is then run to verify that the different components of the switch are
operational. When POST begins, the SYSTEM LED is off. Once POST completes
all testing, and all tests have passed, the SYSTEM LED should turn green. If the
LED is amber, you know that at least one test has failed during POST, which is
usually catastrophic for the switch: in other words, the switch won't boot up.
Running POST takes about a minute.
Assuming that the POST tests pass, at least the critical ones, the IOS continues
executing. Once the IOS completely loads, a configuration is found and applied
to the switch, and you'll be presented with the User EXEC prompt, assuming you
are connected to the console port of the switch. An example of the 2960's bootup
process is shown here:

The password-recovery mechanism is enabled.
