Installing the Switch
Building a Stack of Four to Eight Switches
52
To build a stack of four to eight Ethernet switches with the optional
AT-Stack8 Stacking Matrix Module, perform the following steps:
1. Select an AT-8316F or AT-8324 Ethernet switch in which to install
the AT-Stack8 module. This switch will be referred to as the master
switch. The other switches in the stack will be referred to as slave
switches. In selecting the master switch, observe the following
guidelines:
# The AT-Stack8 module can be installed in either an AT-8316F
or AT-8324 switch, even in stacks that will consist of a
combination of AT-8316F and AT-8324 switches.
# If the Ethernet switches have different versions of the AT-S25
software, install the module into the switch that has the most
recent version of the software.
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 all the Ethernet switches that will be a part of
the stack. 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 optional expansion modules for the switches,
install the modules by performing the procedure 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.
