Building a Stack of Two Switches
To build a stack of two switches, perform the following steps:
1. Select one of the Ethernet switches to be the master switch of the
stack. The other switch will be slave switch. In selecting the master
switch, follow these guidelines:
# The master switch can be either an AT-8316F or AT-8324
switch.
# If the two switches have different versions of the AT-S25 agent
software, select the switch that has the most recent version of
the AT-S25 software as the master switch.
Note
During network operations, the master switch will overwrite the
AT-S25 software in the slave switches with its own version of the
management software. This occurs even if a slave switch contains a
more recent version of the AT-S25 software. For this reason, it is
important that the switch you select to be the master switch have
the most recent version of the management software of all the
switches in the stack.
2. Remove all components from the shipping package and store the
packaging material in a safe location.
3. Locate a level, secure surface for the switches.
Note
If you are building a stack from existing AT-8316F and AT-8324
switches, power OFF the Ethernet switches. If the switches are
connected to an AT-RPS8000 redundant power supply unit, power
OFF the AT-RPS8000 unit using the ON/OFF switch on the back
panel of the unit.
4. If you purchased expansion modules for the switches, install the
modules by following the instructions in the section Installing an
Expansion Module on page 3-60.
5. To install the switches in a rack, perform the procedure Installing
the Switch in a Rack on page 3-45.
6. Connect an AT-CABLE-4 cable between the IS-A ports on the back
panel of the master and slave switches.
