Powering On the Switches Simultaneously

You can let the switches assign their ID numbers automatically by
powering them on simultaneously during the first power-on sequence.
They perform the following steps when assigning their ID numbers:
1. After starting their AlliedWare Plus management software, they
compare their switch priority numbers over the stack trunk of the SFP+
ports S1 and S2.
2. Since they all have the same priority number, the default 128, they
compare MAC addresses.
3. The switch with the lowest MAC address becomes the master switch.
4. The master switch assigns itself the ID number 1.
5. The master switch assigns ID numbers in the range of 2 to 4 to the
other switches.
6. The other switches reboot the AlliedWare Plus management software
with their new ID numbers.
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.

All 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 any of
the switches. 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 have the switches assign the ID numbers automatically, perform the
following procedure:
1. Cable the SFP+ ports S1 and S2 ports on 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.
