Installing And Removing Modules; Preparing To Install Modules - Cisco 1120 Hardware Installation

About Connected Grid Modules
This section describes the installation information for the Cisco Connected Grid modules supported by the Cisco 1120
Connected Grid Router.
The router supports up to two Cisco Connected Grid modules to enable network connections from the router to field
devices, such as smart meters, and from the router to the utility or data management center.
Depending on the configuration, your router could arrive in the shipping container with all required modules already
installed. However, you might need to:

Add a module to your current installation.

Replace a faulty module.

Preparing to Install Modules

Before installing modules in the router, verify the following guidelines have been met:
Note: The CGR 1120 router supports online insertion and removal (OIR) of modules. For more information see
a Module, page 68

Verify that there is adequate airflow around the module slots and through the router vents. For more information, see
Installation Safety and Site Preparation, page

The ambient installation environment temperature must not exceed 140°F (60° C). If the module is installed in a
closed or multi-rack assembly, the temperature around it might be higher than normal room temperature.

The installation environment humidity must not exceed 95% (non-condensing).
