Installing the Router
This section presents installation instructions for the Cisco 1240 Connected Grid Router (CGR 1240 or router). The procedures you follow depend on your network environment and requirements.
■Additional Router Connections
■Installing Modules and Antennas
Before Installing
Read the safety warnings in this section and Installation Safety and Site Preparation before beginning the installation procedures.
Prepare the Installation Site
These procedures assume that the installation site is prepared according to the information in Installation Safety and Site Preparation.
Preventing Electrostatic Discharge Damage
Many of the these components are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly, results in complete or intermittent failures.
To prevent ESD damage, follow these guidelines:
■Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
■Connect the equipment end of the strap to an unfinished chassis surface.
■Place any removed memory card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.
■Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
■Do not remove the wrist strap until the installation is complete.
Cabling Guidelines
Follow these guidelines for using cables with the router:
■Position cables so that they do not place strain on the router connectors.
■Organize cables into bundles when necessary to avoid intertwining.
■Inspect cables to ensure adequate routing and bend radius.
■Install cable ties that comply with your site requirements.

Additional Router Connections
This section provides information about making other, additional router cable connections. Follow the procedures in this section based on your network configuration and requirements. This section contains these procedures:
■External Connections and Chassis Cable Ports
■Connecting the Ethernet Ports
External Connections and Chassis Cable Ports
When connecting the router internal ports to external cables or exterior devices, you must thread the router cables through the chassis cable ports designated for this purpose. Some chassis ports are reserved for specific cables and remaining ports can be used based on your network configuration and cabling requirements.
There are nine cable ports on the chassis base and two ports on the chassis door (Figure 67). Some ports are reserved for a specific cables types, as indicated Figure 67.
Caution: When you make router cable connections through these ports, you must use cable glands as described in Using Cable Glands, to protect the router interior from environmental elements, including moisture, heat, cold, and dust. Failure to use cable glands with the chassis cable ports can result in damage to the router.
Note: We recommend that you cover the ports mentioned in this section with a PG 13.5 plug when they are not in use. Ensure that you torque the PG 13.5 plug to 6 to 7 foot-pounds.
Figure 67 Chassis Cable Ports—For Cabling to External Connectors or Devices
Using Cable Glands
This section describes how to use cable glands with router cables that are threaded through the chassis cable ports described in External Connections and Chassis Cable Ports.
Caution: The cable glands must be used for all cables that are threaded through the router chassis cable ports to prevent exposing the router interior to environmental elements.
Ordering Cisco Cable Glands
You can order a cable gland kit from Cisco using the model number CGR-IP67GLAND. Each kit contains one cable gland. See Router Hardware Description.
