Tech Tip of the Week: When Should You Use a UL Classified Cable Runway?

4/16/2014 2:16:01 PM

Cable Runway SectionsThe UL Classified Cable Runway (also called ladder rack) can be used in any standard cable runway application. 

The National Electric Code (NFPA 70), however, requires the use of UL Classified Cable Runway when it is adopted as an equipment grounding conductor, such as when racks are bonded to the cable runway instead of running an individual ground conductor from the Telecommunications Grounding Bus Bar to each rack.

The UL Classified Cable Runway is a Telco-style, 9’ 8-1/2” long cable runway (ladder rack) with a gold or black chem film over zinc plating. Because UL Classified Cable Runway is zinc plated, it can be bonded together using UL Classified Splices, without the need for ground straps. Installation is therefore, quick and easy.

Chatsworth Products offers two styles of Cable Runway Products – The UL Classified Cable Runway and the Universal Cable Runway.

New Energy Efficiency Improvement Act Recognizes the Value of Proper Data Center Infrastructure

4/14/2014 12:05:45 PM

Data Centers

Last month, the U.S. House of Representatives approved the Energy Efficiency Improvement Act, which requires commercial and federal facilities—particularly data centers—to operate more efficiently.

H.R. 2126 also endorses the development of best practices, and the deployment of energy-efficient and energy-reduction technologies in federal data centers. These federal  facilities consume about 10 percent of all U.S. data center energy use, according to The Green Grid Association. 

If it becomes law, every federal agency will have to consider:

  • Advanced metering infrastructure
  • Energy-efficient data center strategies 
  • Effective power management tools
  • And building energy modeling, among other things

Q&A: An Expert’s Insight into CPI’s eConnect® PDUs

4/8/2014 6:35:41 AM

Andy HungriaMeet Anderson Hungria, Chatsworth Products’ (CPI) Senior Product Manager of Power, Electronics and Software. 

During the past few years, Hungria has been hard at work developing and improving CPI’s line of power management products, including the cutting-edge eConnect® power distribution units (PDUs)

Hungria will present “CPI eConnect PDUs: Advancements and Money-Saving Opportunities in Cabinet Power Distribution,” in this year’s AFCOM Data Center World Conference, April 28 – May 2 at the Mirage Resort, Las Vegas. 

During his product presentation, slated for Tuesday, April 29 from 3 – 4 p.m., Hungria will discuss how the new generation of eConnect PDUs can improve power monitoring, connectivity and operational efficiency in the data center. 

Here, he answers three questions on CPI’s eConnect PDUs:

Why did CPI develop the eConnect line of intelligent PDUs?

Hungria: We developed the eConnect line of PDUs to solve major problems in the data center—PDU design, connectivity and temperature rating—to name a few. One improvement we’ve made, for example, is that eConnect PDUs have a low-profile chassis to minimize cabinet obstruction, and improve airflow and workspace inside the cabinet. Also, the addition of flush-mounted breakers and a unique cord retention system eliminate any potential of accidental disconnections.

We also wanted to reduce the number of ports and network equipment required to monitor our PDUs, so we designed eConnect to be capable of daisy chaining up to 20 PDUs under one single IP address. Other features that we included in the eConnect line are: local display IP address setup, high-accuracy metering and quick deployment through tool-less buttons. 

What makes CPI’s eConnect the best choice in the industry? 

Hungria: CPI offers more than 200 configurations in five different functionalities, which pretty much covers every type of PDU that’s in the market today, including high-density PDUs. Our PDUs are rated to be operational in up to 149F (65C) ambient temperature, making it the market’s highest temperature rated PDU and ideal for any containment application. And as with any other CPI product, eConnect is known for its top quality and customizable design. 

Where do you think the future of power management in the data center is headed?

Hungria: Power management will become more integrated with DCIM and other software solutions, becoming the primary power- and temperature-monitoring point for data centers. PDU customization will continue to be a differentiator for most manufacturers. Data center applications are looking for more power availability, seamless cabinet integration, smaller footprints and even higher temperature rating. And CPI's eConnect PDUs meet all of these criteria.

Passive vs. Active Airflow Management - 2 Sides of the Same Coin

4/3/2014 7:59:52 AM

Cabinets and EnclosuresDo you know what the differences between passive and active airflow management are?

The answer might not be as simple as it sounds. It all depends on how the question is framed.

For example, to some people. active airflow management means adding fans in floor tiles, cabinet chimneys, plenums, etc., to help with air movement. This contrasts to passive airflow management where the only sources of air movement would be the server fans and the primary cooling equipment fans. 

Ian Seaton, Chatsworth Products’ Global Technology Consultant, recently discussed this complex subject in this article from Upsite Technologies.

“Maximum air segregation in conjunction with separate temperature and airflow control loops provide the path to assuring all electronic equipment in the data center is adequately cooled at the most economic energy use,”  he writes. 

When looking for ways to maximize your cooling efficiencies without the need for additional CRAC units, in-row air conditioners or liquid cooling solutions, be sure to check out CPI's Passive Cooling® Solutions. Go here to see how to extend the life of your data center and avoid spending $5-$25 million on a new one.

3/31/2014 12:50:55 PM

Hostirian Cold Aisle ContainmentAchieving complete hot/cold air isolation in the data center is one of the most cooling-effective thermal management practices in the industry today. 

With Chatsworth Products’ (CPI) Passive Cooling Solutions®, for example, it’s possible to avoid adding CRAC units, air conditioners or liquid cooling, all known for increasing energy consumption in the facility.

But these are not the only benefits of airflow isolation. CPI’s Field Application Engineer, Tom Cabral, recently shared seven benefits of airflow isolation in a webcast presentation produced by Cabling Installation & Maintenance (CI&M).

They are:

1. Elimination of hot spots

2. Supports four times higher heat and power densities (6 kW to 30+kW)

3. Effectively uses 100% of supplied air and reduction of chilled air waste 

4. Transfers server equipment ΔT directly back to the HVAC unit

5. Chiller efficiency increase through higher set points

6. Cost-savings increase through higher set points

7. Supply air delivery from ceiling, wall or floor
