When the power is turned on with the local terminal already connected, the switch goes through Power-On Self-Test (POST). POST runs every time the switch is initialized and checks hardware components to determine if the switch is fully operational before completely booting. If a critical problem is detected, the program flow stops. If POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure.
To boot the switch, perform the following steps:
Select an option. If no selection in 10 seconds then operational code will start.
1 - Start operational code.
2 - Start Boot Menu.
Select (1, 2):2
After the switch boots successfully, the User login prompt appears and you can use the local terminal to begin configuring the switch. However, before configuring the switch, make sure that the software version installed on the switch is the latest version. If it is not the latest version, download and install the latest version.
NOTE: Boot menu functions vary on different operating systems and platforms. The following example might not represent the options available on your platform.
You can perform many configuration tasks through the Boot menu, which can be invoked after the first part of the POST is completed. Use the following procedures to display the Boot menu:
