CHAPTER 2: INSTALLATION
2.1 Built-In Ethernet Module
As shown in Table 1.1 (page
7 ), for some OCS Models, the SmartStack Ethernet Module is built-
in to the OCS unit, requiring no user-installation. For example, Figure 2.1 shows the location of
the RJ-45 Ethernet connector on OCS451, OCS551 and OCS651 units.

2.2 User-Installed Ethernet Module
For other OCS or RCS Models, the SmartStack Ethernet Module must be user-installed on the
back of the OCS / RCS unit. Figure 2.2 shows the locations of the Ethernet RJ-45 connector and
LED indicators on the user-installed SmartStack Ethernet Module.
Note: Normally, a user-installed Ethernet Module occupies the first I/O slot on the back of the
OCS or RCS unit. The only exception to this rule occurs if a FOX100 Module is also
installed. In this case, the FOX100 Module occupies the first I/O slot, and the Ethernet
Module is installed into the second I/O slot.
For more details on installing SmartStack I/O modules, refer to Chapter 2 of the Control Station
Hardware Manual (MAN0227), which also provides a handy checklist concerning panel box
layout and minimum clearance requirements.

Caution: For proper functioning and to avoid possible damage, do not install more than
four SmartStack Modules on the back of an OCS or RCS controller.
