Initial Configuration

Selecting the Stack Master
Note the following points about unit numbering:
• When the stack is initially powered on, the Master unit is designated as unit 1 for a
ring topology.
• If more than one stack Master is selected using the Master/Slave push button on
the switch’s front panel, the system will select the unit with the lowest MAC address
as the Master.
• If the Master unit fails and another unit takes over control of the stack, the unit
numbering will not change.
• 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.
Broken Link for Wrap-around Topologies
All units in the stack must be connected via stacking cables.
Note: A single point of failure in a unit will cause the stack to break apart and units will
become independent switches.
Resilient IP Interface for Management Access
If all ports in the stack are members of management VLAN 1, the switch can be
managed from any port in the stack.
Automatic Code Update
If new code if download to the master unit and that code is set as a startup file, then
the code will be automatically updated to the slave units upon reboot.
Basic Configuration
Console Connection
The CLI program provides two different command levels — normal access level
(Normal Exec) and privileged access level (Privileged Exec). The commands
available at the Normal Exec level are a limited subset of those available at the
Privileged Exec level and allow you to only display information and use basic
utilities. To fully configure switch parameters, you must access the CLI at the
Privileged Exec level.
