STACK OPERATIONS

Stack Operations

You can stack up to eight SMC6224M units, four SMC6248M units, or four units when both switch types are stacked together. Refer to the Installation Guide for details on stacking these units. One unit in the stack acts as the Master for configuration tasks and firmware upgrade. All of the other units function in Slave mode.

Note: If more than one stack Master is selected using the Master push button on the switch’s front panel, the stack will not function. Also, if a stack consists of more than one unit, and the Master button is not depressed on any unit, the stack will not function.

Unit Numbering

Note the following points about unit numbering:

When the stack is initially powered on, the Master unit is designated as unit 1 in a ring topology. In a line topology, the stack is simply numbered from top to bottom, with the first unit in the stack designated at unit 1. This unit identification number can be selected on the front panel graphic of the web interface, or from the CLI.

To configure any unit in the stack, first verify the unit number by counting down from the Master unit in a ring topology or from the top unit in a line topology (or use the light unit command to display the unit number via the port LEDs as described on page 4-78),and then select the appropriate unit number from the web or console management interface.

If a unit in the stack fails or is removed from the stack, the unit numbers will not change. This means that when you replace a unit in the stack, the original configuration for the failed unit will be restored to the replacement unit.
