Router Hardware Exterior Features
This section includes detailed information about the exterior hardware features and contains the following topics:
Chassis Enclosure
The Cisco CGR 1240 Router industrial enclosure (see Cisco 1240 Connected Grid Router with Integrated Antennas Installed) meets Type 4X and IP67 standards and is designed for deployment in extreme weather. The enclosure can be painted to comply with aesthetic requirements.
Caution: Painting or otherwise modifying the router enclosure can affect the chassis operating temperature limitations.
UV testing has not been performed on the unit. The chassis has TGIC (triglycidyl isocyanurate) powder coating, so UV will not harm the device. The antennas are a polycarbonate blend and are UV stabilized. The exact life of the device is unknown. However, the device is designed for approximately 10-15 years of life, and there are devices in the field for 10 years already.

Chassis Cable Ports
The router chassis has the following cable ports for router network and power cables:
Cable Glands
A cable gland (also known as a cable connector) is required to install cables in the chassis cable ports. Use a compatible cable gland to attach and secure the end of a cable to the router. The cable gland provides cable strain relief and seals the cable entry into the router chassis to prevent damage to the router interior.
Note : Cable Glands are ordered separately.

Cable Port Seals
Unused router ports are sealed with a liquid-tight cover (PG13) to protect the router interior from environmental elements.
Caution: Do not install the router unless all unused chassis cable ports are sealed. Leaving chassis ports unsealed can damage the router.
Figure 11 Cable Port Seal
Console Port
The router features a single, asynchronous console port (see Router Right Side Exterior and Console Port Detail) for connecting a console or PC directly to the router. To configure the router locally, using the command-line interface (CLI), you must establish a connection to the router with a terminal session.
Caution: This port does not support cable glands; the router interior is exposed to environmental elements while the port is in use. This port should be exposed only during active terminal sessions with the router and should never be left unattended when exposed.
Note: The router also supports wireless console connections with an integrated WiFi short-range access point. For more information see, WiFi Short-Range Access Point.
Console Port Default Settings
The console port does not support hardware flow control. The default settings for the port are: 9600 baud, 8 data bits, no parity, and 1 stop bit.
Connecting to the Console Port
Your router kit includes a console cable with an RJ-45 connector on one end (for connecting to the router console port) and a DB-9 connector on the other end (for connecting to a PC or terminal).
Detailed information about connecting and using the console port is in Installing the Router.
Figure 12 Console Port Detail
SD Flash Memory Module
The router is shipped with one 2-GB Cisco Secure Digital (SD) flash memory module (see Router Left Side Exterior and SD Flash Memory Slot Detail), which stores router software and configurations. For detailed information on using the SD flash memory module with the router, see Using the SD Flash Memory Module.
Figure 13 SD Flash Memory Slot Detail
Caution: You must use only the Cisco SD card designed to support the router. Using an unsupported SD card can impact the router performance, especially in extreme environmental conditions.
10/100BASE-T Fast Ethernet Connector
The router has an external Fast Ethernet (FE) connector (see Router Base Exterior) that enables you to connect the router to an Ethernet hub or switch without opening the chassis.
The external connector is connected to the one of the fast Ethernet ports inside the router chassis. The internal port used depends on the router hardware configuration. If you are connecting the external Ethernet connector to an internal Ethernet port for the first time, Cisco recommends you connect it to the ETH 2/5 port. For more information, see Fast Ethernet Ports.

Protective Vent
The protective vent on the router base (see Router Base Exterior) relieves pressure buildup inside the router chassis that can be caused by changing temperatures in the router installation environment. This prevents pressure from building up and damaging enclosure seals, exposing sensitive components to water. The vent also protects the router interior from dust, dirt, water, and other environmental elements.
AC Power Supply
The router has two power sources: an AC power supply and the battery backup units.
The AC power supply connector on the router base (see Router Base Exterior) is the connection to AC power. If AC power is no longer being supplied to the router, the battery backup units will continue to supply power to the router until AC power is restored. For details about how the battery backup units operate, see Installing Battery Backup Units (BBUs).
Note : The AC power cable part number CGR-PWRCORD-NA or CGR-PWRCORD-EU must be ordered separately.

Router Hardware Interior Features
This section includes detailed information about the interior hardware features illustrated in Router Hardware Overview, and contains the following topics:
Alarm Port
Attach the alarm port inputs (see Router Alarm Port) to an alarm system to monitor external events that occur in the router’s physical installation environment (for example, indicating that the router door has been opened). Attach the alarm port outputs to an alarm indicator such as a siren or light that is enabled by a relay dry contact open or closed circuit. The port supports two alarm inputs and two alarm outputs.
The alarm-trigger setting determines when an alarm is sent to the attached alarm system.
Figure 14 Router Alarm Port
Input Alarm Trigger Settings
- Open —The open setting indicates that the normal (non-alarm state) router operating condition has an electrical current passing through the alarm circuits (DRY contact closed). If this electrical current is no longer detected (DRY contact open), an alarm is generated.
- Closed —The closed setting indicates that the normal (non-alarm state) router operating condition is that no electrical current is passing through the alarm circuits (DRY contact open). If an electrical current is detected (DRY contact closed), an alarm is generated.
Output Alarm Trigger Settings
If interfaces fail or other non-fatal errors occur, the alarm port does not respond. Continue to use SNMP to manage these types of errors.
Note: Due to the RJ-50 pin spacing, the alarm port does not support AC signaling.

Module Slots
The router has four module slots to support installation of up to four compatible Cisco Connected Grid modules, for additional router WAN and NAN interfaces. Modules should be installed in the slots according to the module slot numbers shown in Router Module Slot Numbering and Module Installation Locations. For more information about installing modules, see the corresponding installation and configuration guide for each module at: www.cisco.com/go/cg-modules
Module Numbering
The system software uses a module numbering scheme to identify router components, including the modules. Some system software commands refer to module numbers. The numbers refer to the following router hardware components:
- The router supervisor engine (located on the CPU motherboard) is referred to as module 1.
- The router’s integrated Ethernet switch module, which has four Fast Ethernet ports and two Gigabit Ethernet ports, is referred to as module 2.
- Modules are installed in the router module slots numbered 3–6 (see Router Module Slot Numbering for module slot numbering). For information on the module (3G, WPAN, WiMAX) to slot allocation, see Module Installation Locations.
