Powering On the Switches Individually
This procedure explains how you can control the assignment of the ID
numbers of the switches by powering on the units one at a time during the
initial power-on sequence. The first switch is assigned ID number 1, the
next unit is assigned ID number 2, and so on. This procedure is useful
when the switches are installed in the same equipment rack and you want
to number them in sequence, such as from top to bottom, to make them
easy to identify. After the ID numbers are assigned, the switches retain
their assignments even when you power off or reset the stack.
During the initial power-on sequence, the first switch to be powered on
becomes the master switch of the stack. However, if you do not change
the priority values of the units, the next time you reset or power cycle the
stack, the units use their MAC addresses to select the master switch. This
might result in a different switch being assigned that role. However, this
does not affect their ID number assignments, the configuration of the
switches, or the manner in which you manage the stack.
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 8, “Verifying the Status of VCStack” on page 89.
You connected the switches as explained in Chapter 9, “Cabling
the Stacking Ports” on page 95.
The ID numbers are set to the default 1.
All the switches are powered off.
The grounding and power wires are connected to the DC
connectors on the back panels of the switches. For instructions,
refer to Chapter 5, “Wiring the DC Connectors” on page 61.
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
the switch you intend to power on first. The messages are found in
“Monitoring the Stack Initialization Processes” on page 113.
To power on the switches, perform the following procedure:
1. Power on the DC circuits on the switch you want to have ID number 1.
