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:

Make sure that the serial cable is connected to the terminal.
Connect the power supply to the switch.
Power on the switch.
As the switch boots, the bootup test first counts the switch memory availability and then continues to boot.
During boot, you can use the Utility menu, if necessary, to run special procedures. To enter the Utility menu, press 2 within the first five seconds after the following message displays:
```
Select startup mode.  If no selection is made within 5 seconds,
the 200 Series Application will start automatically...
200 Series Startup -- Main Menu
1 - Start 200 Series Application
2 - Display Utility Menu
Select (1, 2): 2
```
For information about the Utility menu, see Understanding the Utility Menu.
If you do not start the Utility menu, the operational code continues to load.

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. See AutoInstall.
