Chapter 3 Router Hardware Description
Router Overview
•
Integration of Distributed Energy Resources (DER)
•
Remote workforce automation
The router provides reliable and secure real-time communication between network systems and the many
devices that exist on the distribution grid, 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) systems and other
management systems. The router supports physical connection to legacy distribution automation (DA)
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.
Hardware Compliance

management and administration tasks.
SD Flash Memory Module
An external, default 2 GB SD Flash Memory Module stores the
router configuration and data provides ease of managing router
configurations.
USB Port
A Type A USB port for an optional connection to USB storage or
other device, and provides power to the device.
Internal GPS Module
An integrated GPS can provide accurate time and location
information to the system when used with an optional GPS
