Powering On The Switches Sequentially - Allied Telesis x530 Series Installation Manual

Powering On the Switches Sequentially

This procedure explains how to control the assignment of the ID numbers
of the switches 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. You can number them in sequence,
such as from top to bottom, to make 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. 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:
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
For example, when cabling ports 27/S1 and 28/S2 (or 51/S1 and 52/
S2) for the stack trunk, you can either connect the same ports
together, for example, (27/S1 to 27/S1 and 28/S2 to 28/S2) or you
can cross them over (27/S1 to 28/S2). The latter is recommended
but not mandatory.
The switches are at their default settings.

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 the
switch you intend to power on first. For the terminal settings, refer to
"Starting a Management Session" on page 138.
Note
Before powering on the switch, refer to "Power Specifications" on
page 195 for the power specifications of the switches.
