Stacking Guidelines - Allied Telesis AT-SBx908 Installation Manual

Stacking Guidelines

Here are general stacking guidelines:
 A stack can have two, three, or four switches.
 Stacking requires v5.4.8-0.2 or later of the AlliedWare Plus
management software. Instructions later in this guide explain how
to view the version number of the operating software on the
switches.
 The VCStack feature comes standard with the AlliedWare Plus
operating software. No additional software or license is required.

The default setting for the VCStack feature on the AT-SBx908
GEN2 Switch is disabled. Enabling it requires rebooting the switch.
Instructions later in this guide explain how to enable the feature
and reboot the unit.
 All the switches in a stack must have the same optional features
licenses. If you purchased optional features, you should install
them on the switches before assembling the stack.
