4.2.2 To start the equipment

The following table describes the procedures for starting and restarting the Switch.

Table 4-3: Startup and restart methods
Start method	Description	Procedure
Power on	Starts the Switch from the powered-off status.	Turn ON the power by attaching a power cord to the power supply.
Manual restart	Resets the Switch after a failure.	Press the RESET button.
Command restart	Resets the Switch after a failure.	Execute the reload command.
Default restart	Restarts a Switch if you cannot log in because you forgot your password, or if you cannot execute commands from the console for some reason such as an error in configuring command authorization. Take care when performing a default restart. This method does not perform authentication by password, authentication when changing to administrator mode (enable command), or command authorization. A default restart uses the existing account and configuration information. Note that if you have forgotten your login user name, you will not be able to log in after a default restart. The new password set at a default restart takes effect after the Switch is restarted.	Push and hold the RESET button for at least five seconds.

If STATUS light turns on when the Switch is started and restarted, refer to the Troubleshooting Guide. For more information about LED indicators, refer to the "Hardware Instruction Manual."

The Switch boots from the memory card if you start or restart the Switch from an inserted memory card that contains the software image file k.img. When you use this method, the account and configuration information reverts to the factory defaults and you cannot save your own settings. Avoid using this method under normal circumstances.
