In my last blog, we talked about hot-aisle and cold-aisle containment as an ideal solution for keeping equipment cool and saving energy in today’s high-density virtualized data centers.

Depending on the location of the data center and location of the containment system within the data center, some form of fire detection and/or fire suppression is required inside the enclosed aisle.

Let’s take a closer look at fire detection and suppression in the data center and how aisle containment systems can impact the requirements.

The results of the 28th annual Control Engineering Engineers’ Choice Awards are out and I am excited to see that one of our flagship products, the Tofino Security Appliance (specifically the Tofino Xenon version), has received an Honorable Mention award.

The award recognizes control and automation products released in 2014 that are exceptional based on technological advancement, service to the industry and market impact. The Tofino Xenon was recognized in the category of Control Security.

Of significance to Belden is that the winners are not chosen by an expert panel, but by automation professionals from Control Engineering’s subscriber lists. These are people like you who have hands-on, day-to-day interaction with the technologies. Also, you all are responsible for and influence technology purchases.

In case you are not familiar with this product, let’s take a look at some of its unique strengths.

There are some exciting new developments in the world of BASE-T Ethernet and wireless.

Last November, the IEEE 802.3 working group held a Call for Interest (CFI) on the need to develop the next generation BASE-T for wireless access points (WAPs). The main issues raised in the CFI were that next generation 802.11ac Wave 2 devices will require multi-gigabit Ethernet data rates, and that there is a gap between the 1 Gb/s and the 10 Gb/s data rates needed to support Wave 2 devices.

The IEEE 802.11ac wireless standard was approved in December 2013. Current Wave 1 devices are using 80 MHz channels and Single-User Multiple-Input and Multiple-Output (MIMO) antennas with a maximum radio speed of 1.3 Gb/s. To support these devices, the network connection speed needs to be at least 75% of the radio speed. Therefore gigabit Ethernet connections over Category 6 or high-end Category 5e cabling are adequate to support Wave 1 devices.

VFDs, or Variable Frequency Drives, are used by manufacturers to control motors at variable speeds, thus matching the speed of the motor-driven equipment to the load requirement. This provides multiple benefits, such as longer motor life, energy savings, improved process control and higher reliability.

VFDs sound great, and they are, but there is one drawback to them. They generate electrical noise that radiates out and can disrupt electronic equipment, network systems and even instrumentation.

There is a simple way, however, to maximize the benefits of VFDs without decreasing the performance of nearby devices and systems. That way is to make sure that the cables connecting the VFDs to motors are high-performance ones. Furthermore, if the motor is high power (200 horsepower or greater), then parallel VFD cables offer a significant performance benefit.

Let’s take a look at how parallel VFD cables improve the safety and performance of high-power motors.

In today’s high-density virtualized data centers, keeping equipment cool is one of the topmost concerns among data center managers. And the problem is two-fold—not only does cooling represent about 30% of operational costs, but not having uninterrupted proper intake temperatures for equipment can result in overheating and failures that lead to even higher operating costs.

Consequently, many data centers oversupply cold air, placing undue financial strain on data center operations as CRAC units require more power to provide more cool air. And despite the oversupply of cold air, many data centers still experience hot spots.

Defense in Depth is recognized as one of the key best practices for securing industrial networks. It involves using multiple types of defenses at different layers in the network in order to provide higher resistance to attacks than is possible with a single defense, such as a perimeter firewall.

Your first step should be to do a risk assessment and to prioritize your risks and their countermeasures.

In parallel, think about your current defenses, which likely include the perimeter firewall. Do they also include taking advantage of the security functions built in to other network devices?

Most managed Ethernet switches include cyber security features to protect themselves and they are a way to enhance the security of your network at no extra cost. Today’s blog takes a look at some of the security features built into switches, such as those from our Hirschmann and GarrettCom brands.

If you have ever lived in a climate with cold winters and the power has gone out, you likely realized how much we take electricity and heating systems for granted. Not only is it inconvenient on a personal level, it impacts the economy by reducing productivity and disrupting manufacturing processes.

Organizations involved with power generation and distribution work very hard to maintain system uptime of 99.999 percent or better. Achieving that involves many strategies, including maintaining a robust industrial Ethernet infrastructure for communication systems.

Analyses show that 70 percent of communication systems outages are due to failures in network components, cable and connectors.

Let’s look at a major manufacturer of photovoltaic power systems, SMA Solar Technology, which took care to make sure its connectivity systems include high-performing patch panels.
