    NERC CIP & Smart Grid: How do they Fit Together?

    GarrettCom recently published an article "NERC CIP & Smart Grid: How do they Fit Together?" for "Utility Automation T&D" magazine . On the surface, NERC CIP and Smart Grid appear to be complementary and interrelated.  In practice, however, these initiatives are less well-aligned, even disconnected.  The relationship between Smart Grid and NERC CIP depends a lot on how "Smart Grid" is defined.  A broader smart grid definition increases the relationships.  Commonality may be found if one looks at the area of cybersecurity.  Cybersecurity is an essential element of all smart grid initiatives.  NERC CIP is a good start to defining cybersecurity strategies, and it is being refined constantly. Click to Read Article

    SNMP tells only half the story: Don't forget the hardware fix!

    GarrettCom VP of Engineering Lee House recently wrote an article "SNMP tells only half the story: Don't forget the hardware fix!" that has been published in the "Industrial Ethernet Book" magazine. In the article, House discusses that while NMS solutions undeniably provide industrial network operators with a powerful means of managing and controlling infrastructure, these solutions are often not sufficiently integrated with the devices in the network to adequately control the rich capabilities network devices can provide.

    New Perspectives on NERC CIP Access Management

    GarrettCom recently published an article "New Perspectives on NERC CIP Access Managerment" that has been published in "Electric Energy T&D" magazine. In the article, GarrettCom discusses how CIP teams are gaining more perspectives into the scope, interrelationships and evolving requirements of secure access management. The perspectives are then grouped into three areas: real world implementation; preparation of "life under NERC CIP"; and anticipation of ongoing change. Click to Read Article

    NERC/CIP Compliance: Headache or Opportunity?

    In the July, 2007 issue of Utility Automation, the featured article by GarrettCom discusses the challenges of cyber security compliance for power utilities. Government mandates are forcing significant security-related changes in network infrastructure. These mandates can be looked at as intrusive requirements that force unwanted investment in security-specific technologies, or as an opportunity to upgrade infrastructure that creates much broader improvement and benefits.

    Evolving Your Substation Architecture

    This GarrettCom examines the issues and challenges substation network planners face when evolving their substation architectures.  Planners are challenged to integrate SCADA system connections, remote engineering access and other network requirements for substations.  Furthermore, these planners must do it now with minimal cost and make sure the solution will evolve gracefully for many years across emerging requirements for scale, technology, security, performance and manageability.

    The Pros of Conformal Coating

    This paper focuses on choosing the right coating to preserve and protect electronics in harsh environments.  Corrosive gases and chemicals play havoc with components that control and manage processes, or transport vital data between control centers and remote sites.  What is required is a protective coating that can isolate the components from the harsh reality of industrial settings.

    Ethernet Switch Reliability:  Temperature vs. Moving Parts

    The summary of the White Paper is “Common wisdom says that free convection cooling (via heat sinks and other passive means) is the obvious choice for networking equipment in an industrial setting."  GarrettCom, a manufacturer of both free convection and forced convection (via fans), examines this viewpoint via MTBF testing at different temperatures.

    ESD42 Dual-Homing Switches Whitepaper
    Available at Control Engineering

    The summary of the White Paper says “In the past, the choices for redundancy for edge-of-the-network devices were too limited, too expensive, or too complicated to be considered in most industrial systems.  This White Paper, however, contends that today's dual-homing technology can change all that”.
