Powering On The Switches Simultaneously - Allied Telesis AT-x510-28GTX Installation Manual

Powering On the Switches Simultaneously

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,
all you have to do is power them on simultaneously, rather than one at a
time as in the previous procedure. 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 ID numbers to the other switches.

The other switches reset and initialize their management software

again, with their new ID numbers.
This procedure assumes the following:
This is the initial power on sequence of the stack.

You verified that VCStack is enabled on the switches, as explained

in Chapter 5, "Verifying the Status of VCStack" on page 85.
You connected the switches with stacking transceivers, as

explained in Chapter 6, "Cabling the Stacking Ports" on page 91.
All the switches are powered off.

If the stack contains one or more DC powered AT-x510-28GSX-80

Switches, you connected the grounding and power wires to the DC
connectors on the back panels. For instructions, refer to "Wiring
the DC Connectors on the AT-x510-28GSX-80 Switch" on
page 76.
If you want to monitor the power-on sequence, you may connect a terminal
or PC 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 110.
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.
For an AC model switch, connect the AC power cords to the
connectors on the back panel and to the appropriate power sources,
as shown in Figure 59 on page 103. All models have two power
supplies with separate connectors.
