March 2005 Completing a Stacked Configuration 29
4 Now that all switches in the stack are connected,
continue to “Booting the Stack” on page 29.
Booting the Stack
In order for the switches in the stack to operate using their
newly-assigned slot numbers, all switches in the stack must be
manually booted. To manually boot the stack, follow the steps
below.
1 Power on all switches by moving the on/off switch for
each switch to the on ( | ) position.
Important. Be sure to power on all switches in the stack
in rapid succession. If you do not power up all switches
within approximately three seconds, switches may take
unintended stack management roles.
After the stack is completely booted, all switches in the
stack will operate with the user-assigned slot numbers.
Automatic Software Synchronization. In order to ensure
effective redundancy within a stacked configuration, the
primary switch will automatically distribute its system and
configuration software to all switches in the stack as the
virtual chassis boots.
2 If back up power supplies are installed in one or more
switches in the stack, power on all back up power supplies
at this time.
3 After you have booted the stack and powered on all
back up power supplies (if applicable), continue to
“Verifying LED Status” on page 30.
Booting Stand-Alone
Switches
1 To boot a single, stand-alone switch, simply move the
on/off switch for each switch to the on ( | ) position. This
switch is located on the rear panel of the switch, next to
the power cord socket.
Note. Because the switch’s default slot number is 8, the
slot indicator LED displays “8” when the switch is first
booted.
2 If the stand-alone switch has a back up power supply
installed, you may power on this unit as well. Move the
on/off switch for the back up power supply to the on ( | )
position.
3 After you have booted the stand-alone switch and
powered on the back up power supply (if applicable),
continue to “Verifying LED Status” on page 30. This
section provides information on LED states and switch
status both during and after the boot process.
