AT-8316F and AT-8324 Installation Guide

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.

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.
