The x930 Series switches comes with the AlliedWare Plus™ operating
system and a base set of features. These features are available as soon
as you install the devices. Allied Telesis also offers additional features and
capabilities for the switches. These features come with the AlliedWare
Plus operating system, but they have to be unlocked before you can use
them. The features are unlocked with feature licenses from Allied Telesis.
Contact your authorized reseller or distributor for a list of the current
optional features licenses for the switches.
Here are the guidelines to feature licenses for a stack of x930 Series
switches:

The VCStack feature is part of the base features of the switch and
does not require an optional feature license.
 You may install feature licenses while the switches are operating
as stand-alone units or as a stack.

When ordering feature licenses for the switches of a stack, you
must order one license for each switch.
 The switches will form a stack even if they have different feature
licenses. However, the additional features are only available on
those switches that have the necessary licenses. The stack
generates a warning message if it detects that the switches do not
have the same optional feature licenses.
