Expansion Module Slots
The capabilities of the AT-8316F and AT-8324XL Ethernet switches
can be expanded by installing optional expansion modules in the
two expansion slots on the front of the switches (shown in Figure
1-9).
Figure 1-9 Expansion Slots
The modules offer you flexibility in building or expanding your
network. For example, you can use the modules to build a high-
speed backbone network between different switches, to expand the
number of ports on a switch for additional nodes, or to provide a
high-speed connection to shared devices, such as servers or routers.

Expansion
Modules
Table 1-4 lists the optional expansion modules for the AT-8316F and
AT-8324 Ethernet switches. The modules can be installed in any
combination in the switch. For example, you can install an AT-A15/LX
module in one expansion slot and an AT-A18 module in the second
expansion slot of the same switch.
