Powering On the Switches Simultaneously

96
If you want the switches of the stack to use their MAC addresses to
automatically assign the ID numbers during the initial power-on sequence,
and to select the master switch themselves, power them on
simultaneously. Here are the steps the switches perform:
 They initialize their management software and compare their MAC
addresses.

The switch with the lowest address is designated as the master
switch of the stack.
 The master switch assigns itself the ID number 1.
 The master switch assigns the ID number2 to the other switch.
 The other switch resets and initialize its management software
again, with its new ID number 2.
This procedure assumes the following:

This is the first power-on of the stack.

You verified that VCStack is enabled on the switches, as explained
in Chapter 6, "What to Do First" on page 81.
 You verified that both switches have the same version of the
AlliedWare Plus management software. Refer to "Displaying the
AlliedWare Plus Version Number" on page 88.
 You cabled the 15/S1 and 16/S2 ports with stacking transceivers.
Refer to "Installing AT-StackXS/1.0, AT-SP10TW1, or AT-
SP10TW3 Cables" on page 136.

The ID numbers are set to the default 1.
 The switches are powered off.
If you want to monitor the power-on sequence, you can connect a terminal
or computer with a terminal emulator program to the Console port on any
of the switches. The messages are found in "Monitoring the Initialization
Processes" on page 101.
To have the switches automatically assign the ID numbers, perform the
following procedure:
1. Power on all the switches in the stack at the same time. Refer to
"Powering on a Switch" on page 83.
Note
Refer to "Power Specifications" on page 144 for the power
specifications of the switches.
