Planning The Stack - Allied Telesis AlliedWare Plus GS980MX Series Installation Manual

Planning the Stack

Here are factors to consider when planning a stack:
Have you selected the stack ports for the trunk? The default stack

ports are 10Gbps ports. Refer to "Stack Trunks" on page 63.
How many GS980MX switches will be in the stack? The maximum

is four switches.
Have you determined the required number of SFP+ transceivers or

SP10TW direct attach cables? Refer to Figure 29 on page 75 and
Figure 30 on page 76.
Have you selected a master switch? This can be any switch. If the

switches have different versions of the AlliedWare Plus
management software, the master switch should have the most
recent version. Refer to "Selection of the Master Switch" on
page 79.
Have you selected ID numbers, in the range of 1 to 4 for the

switches? If you are using the default stacking ports, you can
control the ID number assignments by the order in which you
initially power on the switches, or you can have the switches assign
the numbers automatically. Refer to "Switch ID Numbers" on
page 81.
Have you already connected network cables to the trunk ports? If

so, you should disconnect them before configuring the switches for
stacking.
