Chapter 3: Stacking

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.
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.
5. Suspend the startup process by pressing or within two
seconds and the following message is displayed:
