Booting the Switch 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: 1. Ensure that the serial cable is connected to the terminal. 2. Connect the power supply to the switch. 3. Turn on the switch. As the switch boots, the boot test first counts the switch memory availability and then continues to boot. 4. During boot, you can use the Boot menu, if necessary to run special procedures. To enter the Boot menu, press 2 within the first ten seconds after the following message appears. 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 For information about the Boot menu, see "Boot Menu Functions."
