Note: The onboard program only provides access to basic configuration

functions. To access the full range of SNMP management

functions, you must use SNMP-based network management

software.

Stack Operations

Up to eight switches can be stacked together as described in the

Installation Guide. One unit in the stack acts as the Master for

configuration tasks and firmware upgrade. All of the other units function

in Slave mode.

To configure any unit in the stack, first verify the unit number of the

switch (i.e., switches are numbered downward in the stack starting with the

Master as unit 1), and then select the appropriate unit number from the

web or console management interface.

Selecting the Stack Master

Note the following points about unit numbering:

• The unit identification number can also be selected on the front panel

graphic of the web interface, or from the CLI.

• If the Master/Slave button is pushed in on more than one switch, or is

not pressed on any switch, the system will not be able to initialize the

stack connections.

Recovering from Stack Failure or Topology Change

When a link or unit in the stack fails, a trap message is sent and a failure

event is logged. The stack will be rebooted after any system failure or

topology change. It takes two to three minutes to for the stack to reboot.

Also note that powering down a unit or inserting a new unit in the stack

will cause the stack to reboot.
