Powering On the Switches Simultaneously

108
If, during the initial power-on sequence of the stack, you want the switches
to automatically assign the ID numbers themselves using their MAC
addresses, you can power them on simultaneously. 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 the ID number 2 to the other switch,
which becomes a member switch of the stack.

The member switch resets and initialize its management software
again, with its new ID number 2.
The process takes about four minutes. 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 6, "Verifying the Status of the Switches" on page 85.
 You connected the QSFP+ transceivers in slots 17 and 21 of the
switches, as explained in Chapter 7, "Installing the Stacking
QSFP+ Transceivers" on page 99.

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 either of
the switches. The messages are found in "Monitoring the Initialization
Processes" on page 113.
To have the switches automatically assign the ID numbers, perform the
following procedure:
1. Power on both the switches of the stack at the same time.
Connect the power cords to appropriate power sources. Refer to
Figure 43 on page 89.
Refer to "Power Specifications" on page 132 for the power
specifications of the switches.
