Planning The Stack - Allied Telesis AT-SB*908 GEN2 Installation Manual

Planning the Stack

Here are factors to consider when planning a stack:
 How many SBx908 GEN2 Chassis will be in the stack? The
maximum is four chassis.
 How many trunk links will there be between switches? The
maximum numbers of permitted links vary by Ethernet line card
and are listed in Table 10 on page 46.
 Which ports will be the trunk links? Refer to "Stacking Guidelines"
on page 41.

Do all the switches have the same version of the AlliedWare Plus
management software, preferably v5.4.8-0.2 or later? Instructions
on how to verify this information is explained later in "Viewing the
AlliedWare Plus Version Number" on page 149.
 Do all the switches have the same optional feature licenses?
Instructions on how to verify this information is explained later in
"Viewing Optional Feature Licenses" on page 150.
 Have you selected ID numbers, in the range of 1 to 4, for the
switches? 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 57.
