Configuring Stacking
Configuring stacking is performed during the bootup process. To configure a device as part of a stack, the bootup process must be interrupted straight after the Power On Self Test (POST).
To configure the device for stacking, perform the following:
1.Ensure that the device console is connected to a VT100 terminal device or VT100 terminal emulator.
2.Deactivate the AC power receptacle.
3.Connect the device to the AC receptacle.
4.Activate the AC power receptacle.
When the power is turned on with the local terminal already connected, the switch goes through 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 following screen is an example of the displayed POST.
