Overview
Devices can either function on their own, or they can be connected into a stack of devices in
various stacking modes (see Stack Unit Mode).
By default, a device is always stackable, but has no port configured as a stack port. All the
ports in the devices are configured as network ports by default. A device without any stack
port can be thought of as the master device in a stack of only itself or as a standalone device.
To stack two or more devices, reconfigure the desired network ports as stack ports in the
devices and connect the devices with the resulting stack ports in a ring or chain topology.
