Chapter 8: Powering On the Stack
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
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
You verified that VCStack is enabled on the switches, as explained in Chapter 6, “Verifying the Status of VCStack and Activating VCStack” on page 85.
You connected the switches with stacking transceivers, as explained in Chapter 7, “Cabling the Stacking Ports” on page 91.
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 73.
To power on the switches, perform the following procedure:
1.Power on the switch you want to have ID number 1.
Connect the power cords to the connectors on the power supply modules and to the appropriate power sources, as shown in “Connecting AC Power to a Power Supply Module” on page 70.
2.Wait one minute for the switch to initialize its management software. The switch should be displaying the number 1 on its ID LED.
3.Power on the switch to be assigned ID number 2.
