Figure 4. Securing the AT-StackXG Stacking Module
Note
The remaining steps attach the stacking cable to the stacking module. If
you are installing the stacking module in an AT-9400 Series Switch, do
not cable the module until you have prepared the switch's AT-S63
Management Software, as explained in the AT-9400 Series Stack
Installation Guide.
Note
If you are installing the stacking module in an x600 Series Switch, do not
cable the module until you have prepared the switch's AlliedWare Plus
Software on the x600 Series Switches as explained in the x600 series

module and secure by tightening the two captive thumbscrews.
7. Remove the plastic protector from the connector at the other end of the
stacking cable and connect it to a Stack Port on the stacking module in the
next switch of the stack. A stacking cable must crossover and connect to
a different port on the next stacking module. Stack Port 1 on a module
must connect to Stack Port 2 on the next module. Do not connect two
Stack Port 1 ports or Stack Port 2 ports together.
