Activate the AC power receptacle.
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 device is initialized and checks hardware components to determine if the
device 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.
As the switch boots, the bootup test first counts the device memory availability and then continues to boot. The fol-
lowing screen is an example of the displayed POST.
The boot process runs approximately 30 seconds.
The auto-boot message that appears at the end of POST (see the last lines) indicates that no problems were
encountered during boot.
During boot, the Startup menu can be accessed if necessary to run special procedures. To enter the Startup menu,
press <Esc> or <Enter> within the first two seconds after the auto-boot message is displayed. For information on
the Startup menu, see "Startup Menu Functions."
If the system boot is not interrupted by pressing <Esc> or <Enter>, the system continues operation by decom-
pressing and loading the code into RAM. The code starts running from RAM and the list of numbered system ports
and their states (up or down) are displayed.
