Every year, the rail industry spends billions of dollars to improve the national infrastructure. For example, American freight railroads spent $28 billion in 2014, and a projected $29 billion in 2015 on infrastructure and equipment. Although new projects draw the most attention, the majority of spend is on routine maintenance repair operations to ensure continuous safety and efficiency of the railroad system. There is a definite correlation between the increase in rail network investments and enhanced safety performance.
After a recent US passenger train accident last month, the Federal Railroad Administration issued a safety advisory for passenger railroads. The railroads are recommended to use an existing technology called Automatic Train Control (ATC) to alert trains appearing to be travelling at an excessive speed, in hopes they reduce their speed as they approach a curve or bridge. (On May 12, 2015, an Amtrak passenger train carrying 243 passengers and crew members derailed killing eight and injuring more than 200. The train was travelling well above the allowable speed limit for that area).
Wireless Access Points (WAPs) have become a common installation in the Enterprise space. How do you know what cabling infrastructure is right to get optimum performance from your WAP? The answer is simple: new permanent installations call for Category 6A.
Category 6A is required to support 10GBASE-T
10GBASE-T will be the dominant new speed in a few years
The rollout of new AC wireless access points in the enterprise represents the first multi-gigabit application to be deployed in the enterprise. This is a perfect time to review the media choices being made to ensure your physical infrastructure is capable of supporting the application for the life of the enterprise. If we compare the relative cost per Gigabit for category 6A and single gig infrastructures, we find that category 6A (10GBASE-T) is more cost-effective per gigabit:
Ethernet network cabling in the enterprise is almost exclusively based on structured cabling. Greatly simplifying , structured cabling is based on connecting equipment, e.g. network switch to a personal computer, using solid conductor horizontal cable terminated at both ends with a jack mounted in a patch panel, wall faceplate or similar, and then making the connections from the jacks to active equipment using flexible, stranded patch cords. One benefit of doing this is that the horizontal cable with jacks forms the basis of a testable permanent link.
Historically, there has been little convergence between manufacturing and enterprise in the plant network. Instead, there are multiple, separate networks – one network may run fieldbus protocol at the device level, another network may run ControlNet protocol for machine-to-machine
communications, while a third protocol, such as Ethernet, or a proprietary network, links the machines to data acquisition and storage units for reporting or archiving. Meanwhile, a separate network, often an extension of the office Ethernet network, is on the plant floor, enabling workstation access to work orders and task instructions.
Keeping your communications and power cables properly and safely installed in harsher environments such as Shipbuilding, Oil & Gas, and Chemical processing plants, as well as other similar applications, can be a challenge. However, it needs to be taken very seriously, otherwise the facility and personnel are being placed at elevated risk of injury or other adverse effects.
In order to ensure that proper cable fastening solutions are being implemented in these harsh environments, many times stainless steel cable ties will be specified for use. However, not all stainless cable ties are created equal, and it is critical to thoroughly evaluate available options in order to choose the one that is safest and most reliable.
The Wyr-Grid tray is “upside down” because the design is based on a strong wire mesh platform reinforced with 1-1/2” high wire mesh walls that are oriented downward giving the appearance of an up-side down wire mesh tray. While appearing unconventional, this design combines the best attributes of cable runway with the flexibility and utility of wire mesh pathways.
The NFPA 70E Standard provides guidelines for electrical safety in the workplace. Recently this standard has been updated to provide consistency of terms with other standards that address hazards and risk.
Some of these changes introduced new terms such as arc flash risk assessment to replace arc flash analysis and shock risk assessment to replace shock hazard analysis.
Determining the Arc Flash Risk Assessment and Shock Risk Assessment for electrical devices provides important information to warn of the specific risks associated with an energized piece of equipment. This information is communicated to workers through the use of equipment labels.
In Section 130.5(D) of the 2015 NFPA 70E Standard new requirements for Arc Flash Warning Labels are explained.
Last week I posted a blog about what is driving the adoption of high density fiber enclosures. High density fiber enclosures can help reduce the high cost of real estate. Possibly, one might find themselves with a data center where space is constrained so a high density fiber enclosure can help ease those space constraints. I also said that high density fiber enclosures are used in data centers that are revenue generators because they make it possible to include more revenue-generating active equipment.
So a high density fiber enclosure helps add more equipment to a finite amount of space, but, as they say, there is no free lunch.
Real estate is one of the primary reasons that high density fiber enclosures are deployed in the data center. In some parts of the world, real estate is very expensive. One way to save cap ex is to try to use the smallest data center possible. The smaller the data center, the less square area required, and therefore, lower cap ex. This would certainly be the case if one is using a co-lo facility. Of course, a smaller data center also means lower op ex, e.g., less cooling, etc.
Another reason, also driven by real estate, is that the data center’s size is fixed. The data center cannot be enlarged. This might be the situation in dense urban areas where a larger space does not exist. The only way to add more functionality to the data center is to try and find a way to cram in more equipment. Hence, using a high density fiber enclosure.
Another less obvious reason for using a high density fiber enclosure is the trend towards data centers becoming profit centers. Historically, data centers were perceived as a cost of doing business. Depending on the business you are in, that may no longer be the case.
