Overview
Devices can either function on their own (Standalone mode), or they can be
connected into a stack of up to eight devices in various stacking modes (see
Stack Unit Mode).
The devices (units) in a stack are connected through stack ports. These devices
are then collectively managed as a single logical device.
The stack is based on a single master/backup and multiple slaves model.
