Who doesn’t want an efficient, cost-effective, high-performing network? IT professionals dedicate themselves to achieving this goal, and there are several ways to make it happen. In the quest to save money, it’s not uncommon for network managers to consider low-quality, cheap patch cords. But not all patch cords are created equal. Cheap patch cords may not match standards, and can cause signal degradation.

Variable frequency drives (VFDs) are essential to the industrial world. From fans and pumps to conveyors and mixers, VFDs deliver energy savings and more precise process control, while also reducing the wear and tear on other industrial equipment.

VFD applications, however, present unique challenges due to their management of electrical current and other factors.
Thus, it’s essential to make sure your system uses high-quality cabling and proper installation procedures.

It’s important to keep in mind there is no industry standard for VFD cables – so, any manufacturer can claim to make cables for AC motors and drive applications. A “real” VFD cable, however, is designed to keep current within the cable and not disturb nearby equipment, networks or instrumentation. If you build your VFD system with lower-quality, or non-VFD cable, you can put both personnel and operations at risk.

So what should you look for in a cable to know if it’s a real VFD cable? Read on to find out what to consider when evaluating industrial cabling for your VFD application.

There aren’t a lot of options when it comes to choosing data center cabinet, enclosure and rack colors. The standard is obviously black, and has been for years – likely due to cost and production reasons. The most common color alternatives are gray and white.

In this blog, we outline a few of the potential issues that dark cabinet and rack colors can cause, and why a lighter color inside and out – such as white or gray – might be an option worth considering the next time you need to purchase this equipment.

The SANS 2016 State of ICS Security Survey Report indicates that many of the ICS professionals who responded to the survey have new job titles such as ICS cyber security program manager, ICS security project manager, IT/OT architect and director of cyber security for building and facilities systems.

This trend indicates that industrial cyber and cyber-physical security is a rising priority and industrial companies are beginning to assign staff with ICS security responsibility. While attending the recent EnergySec 12th annual security summit held in Anaheim, California on August 22-24, I spoke to many ICS operations attendees with new job titles and security responsibilities reflecting this priority. They had come to EnergySec for information sharing and practical guidance on the security challenges they’re facing.

While there I had a chance to ask EnergySec’s new president Steve Parker a few questions about EnergySec, trends, concerns and the state of ICS security within power and energy critical infrastructures.

For those of you who may not be familiar with this non-profit organization, they are approaching 1500 members and 470 member organizations, have achieved SANS Institute awards, and a good history of their grass-roots founding over a decade ago is posted on their website.

Speed: It’s what everyone in our industry ultimately craves. When networks are fast, many things happen: work is completed quickly, customers are happier, frustrations are kept to a minimum and unplanned downtime doesn’t negatively impact business performance.

In our conversations about speeding up networks, one phrase is becoming more common: content delivery network (CDN). Content delivery networks can enhance network performance across the globe in a simple platform. Here, we explain what a CDN is, why it’s being used and how it impacts speed and bandwidth.
