Router Hardware Description

This section describes the major hardware features of the Cisco 1240 Connected Grid Router (CGR 1240 or router), including the chassis, internal and external connectors and ports, and hardware specifications.

These topics are discussed:

Router Overview

Router Applications Overview

The CGR 1240 is a ruggedized communication platform, designed for use in Field Area Network (FAN) power distribution grids that require outdoor, pole-mounted routers. The FAN is a distribution system in which power generation and transmission are linked to the power consumers.

The router provides an end-to-end communication network that enables increased power grid efficiency and reliability, reduced energy consumption, and reduced greenhouse gas emissions. The router can be leveraged across applications including:

  • Advanced Metering Infrastructure (AMI)
  • Distribution Automation (DA)
  • Integration of Distributed Energy Resources (DER)
  • Remote Workforce Automation
  • Public Lighting

The router provides reliable and secure real-time communication between the FAN systems and the numerous devices that exist on the FAN, including meters, sensors, protection relays, Intelligent Electronic Devices (IEDs), plug-in electric vehicle (PEV) charging stations, and distributed solar farms. Network data is forwarded and processed over secure communication links between devices within the distribution grid for local decision processing.

Additionally, this data is sent to Supervisory Control and Data Acquisition (SCADA) and other management systems. The router supports physical connection to legacy Data Acquisition devices (over the serial port); the data from these devices can also be sent to central SCADA systems using protocol translation over the IP network.

Figure 11 Cable Port Seal

 

300542.eps
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.

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

 

300545.eps
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.

Combo Ports

The combo ports are two Gigabit Ethernet ports and two SFP ports on the router that are labeled identically. GE Ports and SFP Ports Share Interfaces ETH 2/1 and ETH 2/2 shows the ports.

The GE and SFP ports share the same physical ports or connections and are labeled identically on the router (ETH 2/1, ETH 2/2) and in the software (GE 2/1, GE 2/2). Cisco CGR 1240 Gigabit Ethernet and SFP Port Naming describes the port naming on the router and in software.

The Gigabit Ethernet ports support copper GE connections and the SFP modules support fiber optic GE connections. Only one connection on each interface (ETH 2/1 and ETH 2/2) can be in use at any time.

These ports automatically detect the type of any connected cable (fiber or copper) and then switch to the corresponding mode (fiber or copper).

Note: If connections are made to both interfaces of the same name (ETH 2/1 or ETH 2/2), only the first connection that establishes a link is enabled.

WiFi Short-Range Access Point

The router features an integrated, short-range WiFi access point to support a wireless console connection to the router. Generally, the router is installed on a pole above the ground, which makes a wired console connection impractical during router operation.

The WiFi connection is available only when the system software is operating. If the system software is not operating, you cannot use the WiFi connection to connect to or administer the router.

When running IOS, Wi-Fi can be used as an access point for up to 5 devices, but also as a layer-3 interface.

WiFi Hardware

The CGR 1240 router is equipped with an 802.11b/g/n 2.4GHz radio that works as the access point to provide WiFi connectivity to the router. The WiFi hardware is a Broadcom BCM4325 chipset based radio with an external WiFi antenna.

WiFi Default Settings

The default WiFi interface identity settings for the Cisco CG-OS and Cisco IOS operating systems are detailed in Default WiFi Interface Identity Settings.

Note: The CGR 1240 WiFi interface is assigned to module 2 and cannot be changed.
