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 number 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 5, “Verifying the Status of VCStack” on page 77.
 You connected the switches with stacking transceivers, as
explained in Chapter 6, “Cabling the Stacking Ports” on page 83.
 The ID numbers are set to the default 1.
 .All the switches are powered off.
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
Initialization Processes” on page 99.
Before powering on the switch, refer to “Power Specifications” on
page 116 for the power specifications.To install the power cord retaining
clip and power on the switch, perform the following procedure:
To power on the switches, perform the following procedure:
1. Power on the switch you want to be assigned ID number 1 by
connecting its power cord to the AC connector on the back panel and
to an appropriate power source. Refer to Figure 43 on page 92. Refer
to “Power Specifications” on page 116 for the power specifications of
the switches.
