Step 6: Install the Smart Switch as a Stack Master or Stack
Slave
The smart switch can function as a master, backup master, or slave in a stack. (For more
information about stacking, see
A backup master runs as a slave. In addition, it continuously monitors the existence and
operation of the master. If the master fails, the backup master assumes the role of the master
through a switchover. In the default configuration, the master and backup master are
assigned unit ID 1 and 2, respectively. However, you can use the web management interface
to assign different unit IDs. The goal for switchover time is less than 30 seconds.
If a stacking cable fails or a stack member is extracted in a chain topology, slaves could be
disconnected from the stack (which puts them in an ambiguous state), causing all their ports
to enter the down state.
Each stack member can work in one of two modes: slave mode or master mode. The
operational mode is determined at software boot time and can be changed only by a unit
reset. The Segment Stack ID LED remains lit in both modes.
The smart switch supports two stacking topologies: ring topology and chain topology.

The smart switch is a plug-and-play device in terms of setting up a stacking configuration.
Before powering up the smart switch, connect the devices into the required stacking
topology. Then power up the smart switch and the other devices. By default, the smart switch
is configured to allow the master and slave designations to be determined through automatic
discovery. After the smart switch boots and is operational, you can use the web management
interface to configure the stack to select a particular switch as master.
For more information about stacking, see the S3300 Smart Switch Software Administration
Manual. The resource CD includes a link to this document.

Step 7: Apply AC Power

The smart switch does not provide an on/off switch. The power cord connection controls the
power.
Before connecting the power cord, select an AC outlet that is not controlled by a wall switch,
which can turn off power to the smart switch.
