Powering On the Switches Sequentially

This procedure explains how to control the assignment of the switch ID
numbers by powering on the units one at a time during the first power-on
sequence. The first switch is assigned ID number 1, the next unit ID
number 2, and so on. This procedure is useful when the switches are
installed in the same equipment rack because you can number them in
sequence, such as from top to bottom, making them easier to identify.
In this procedure, the first switch powered on becomes the master switch
of the stack. If you do not change the priority values of the switches and
later reset or power cycle the stack, the switches will select the master
based on their MAC addresses. This could result in a different switch
becoming the master switch of the stack. However, this does not change
their ID numbers, the stack configuration, or the manner in which you
manage the stack.
This procedure assumes the following:
You performed "Displaying the Hardware Status and AlliedWare

Plus Version Number" on page 115 to confirm that all the switches
have the same version of the AlliedWare Plus management
software.
This is the first power-on of the stack.

The switches are powered off.

You can monitor the power-on sequence by connecting a terminal or
workstation with a terminal emulator program to the Console port on the
switch you power on first. For the terminal settings, refer to "Starting a
Local Management Session" on page 112.
Note
Refer to "Power Specifications" on page 169 for the power
specifications of the switches.
To control the assignment of the ID numbers to the switches, perform the
following procedure:
1. Cable the SFP+ ports S1 and S2 on all the switches of the stack. For
guidelines and examples, refer to "SFP+ Ports S1 and S2" on page 46.
For cabling instructions, refer to Chapter 11, "Cabling Copper and
SFP+ Ports" on page 149.
2. Power on the switch you want assigned ID number 1. Refer to
"Powering On the Switch" on page 110.
