Chapter 7: Building the Trunk with the Default SFP+ S1 and S2 10Gbps Stacking Ports

Powering On the Switches Simultaneously
This procedure powers on the switches simultaneously. They assign their
ID numbers automatically by performing the following steps:
1. They start the AlliedWare Plus software.
2. They compare their switch priority numbers over the stack trunk.
3. Since they all have the same priority number, the default 128, they
compare MAC addresses.
4. The switch with the lowest MAC address becomes the master switch.
5. The master switch assigns itself the ID number 1.
6. The master switch assigns ID numbers to the other switches.
7. The other switches reboot the AlliedWare Plus software with their new
ID numbers.
This procedure assumes the following:
This is the first power on sequence of the stack.
You cabled ports on the switches to form the stack trunk.
– x530-10GHXm: SFP+ ports 9/S1 and 10/S2
– x530-18GHXm: SFP+ ports 17/S1 and 18/S2
– x530-28GTXm, x530-28GPXm or x530-28GSX: SFP+ ports
27/S1 and 28/S2
– x530-52GTXm or x530-52GPXm: SFP+ ports 51/S1 and 52/S2
Note
As explained in “Stack Trunks” on page 63, you can connect the
same ports together (e.g., S1 to S1 and S2 to S2) or you can cross
them over (e.g., S1 to S2 and S2 to S1). Allied Telesis recommends
the latter.
The ID numbers are set to the default 1.
The switches are powered off.
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. For the terminal settings, refer to “Starting a Management
Session” on page 138.
