Installing and Removing a SmartStack Module
The following section describes how to install and remove a SmartStack Module.
Caution: To function properly and avoid possible damage, do not install more than four
Smart Stack  Modules per OCS, RCS, NX, QX, FOX base/hub or TIU.
Do not attempt to install or remove a SmartStack module with the units powered on.
Installing SmartStack Modules
10 Hook the tabs. Each SmartStack Module has two tabs that fit into slots located on the OCS,
RCS, FOX base or TIU. (The slots on the OCS are located on the back cover.)
11 Press the SmartStack Module into the “locked” position, making sure to align the SmartStack
Module fasteners or clip with the SmartStack receptacles on the main housing.
Removing SmartStack Modules

SmartStack Module (opposite end to tabs) and swing the module out. In the case of a plastic
Smartstack module press the button in the end of the module and swing the module out.
