Booting the Stack
In order for the switches in the stack to operate using their
Important. Whenever booting a stacked configuration, note that the primary switch will automatically distribute its system and configuration software to all switches in the stack whenever the virtual chassis boots. During this automatic software synchronization, system and configuration software on the second- ary and idle switches is overwritten. Because the primary switch’s “last known good” software is propa- gated to all switches, the synchronization process helps ensure effective redundancy across the stack.
To manually boot the stack, follow the steps below.
1Power 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.
2If back up power supplies are installed in one or more switches in the stack, power on all back up power supplies at this time.
Verifying Slot Number Assignments
After the stack is completely booted, all switches in the stack operate using the
Verifying Primary and Secondary Status for the Stack
Primary, Secondary and Idle switch status is indicated by the PRI and SEC LEDs. The PRI and SEC LEDs on the switch’s front panel are the most accurate and reliable method for determining the current role of a switch within a stacked configuration.

Now that the stack has been configured and booted, the
To verify this, check the PRI LED on the front panel of the switch with the lowest assigned slot number. The PRI LED should be illuminated solid green.

The secondary role is given to the switch with the
