so that its active master controller card becomes the active card for the
stack and its configuration file is used as the initial configuration for the
stack.
After the stack is operating, the active master card periodically shares its
configuration file with all the other controller cards in the stack. Thus, the
order in which the units are subsequently reset or powered on is not
important because all the controller cards have the same configuration file.
Powering On the
Switches
To power on the two chassis of the stack, do one of the following:
 To power on the AC AT-SBxPWRSYS1, AT-SBxPWRSYS2, and
AT-SBxPWRPOE1 PoE Power Supplies, connect the power cords
to the appropriate connectors on the back panel and to power
sources. For instructions, refer to “Powering On the AT-
SBxPWRSYS1 or AT-SBxPWRSYS2 AC System Power Supply”
on page 195 and “Powering On AT-SBxPWRPOE1 Power
Supplies” on page 198, respectively.
 To power on AT-SBxPWRSYS1 DC Power Supplies, turn the
power switches to on. Refer to Figure 64 on page 139.
Be sure to power on all the power supplies in the chassis.
Note
To power on the two chassis in sequence to control the selection of
the active master controller card, power on the unit that has the
controller card to be the active master controller card, wait a
minimum of ten seconds, and then power on the second unit.
The boot up sequence for the stack takes approximately four minutes. The
amount of time may vary, depending on the number and types of Ethernet
line cards in the two switches. The ports do not begin to forward traffic until
the stack has completed the initialization process. Do one of the following:
 If you want to monitor the switches as they perform the initialization
process, go to “Monitoring the Boot Up Sequence” on page 334.

If you do not want to monitor the initialization process, go to
“Verifying the Stack” on page 337.
Monitoring the
Boot Up
Sequence
You may monitor the initialization process by connecting a terminal or PC
with a terminal emulator program to the Console port on any of the
controller cards and watch the status messages, shown in Figure 199 on
page 335 and Figure 200 on page 336. (The settings for the terminal or
terminal emulator program are found in “Using Local Management to
Verify the Chassis” on page 234.)
After the stack has completed the initialization process, go to “Verifying
the Stack” on page 337.
