la adds, it is essential to get the personnel running them
together. Today, that’s often the case. “It used to be that when I
would go to a customer, I would talk to the IT personnel,” Villa
says. “Today, I talk to facilities personnel—plumbing, electri-
cians, and others. Everyone is on the same page much earlier
in the process than in the past.”
Marc Naese, solutions development manager with Panduit
(www.panduit.com), says, “Overall, we see four critical areas
of the data center: the entire infrastructure, network compo-
nents, storage components, and computing resources. All four
areas must interoperate.” Naese adds, “We have developed our
solutions to address specific issues in each of those areas. On a
room level, cooling supports the entire ecosystem. As you get
down to a rack or cabinet level, the needs change drastically.
Side-to-side versus front-to-back airflow is an example.”
Naese concludes, “Before you can understand your power or
cooling requirements, you must know how many servers you
are going to deploy. From there, you can calculate what your
requirements will be, what the cabinets will look like, and how
dense those cabinets will be.”
Keep them separated
Ian Seaton, technology marketing manager with Chatsworth
Products Inc. (www.chatsworth.com), points out, “When you
follow industry understanding of best practices, everything
that is done in the data center is really designed to separate the
supply air from the return air as much as possible. That’s why,
he explains, the hot-aisle/cold-aisle setup was established: “It’s
why you seal off access cutouts, install blank tiles, and locate
your cooling units in the hot aisles so you prevent your return-
air path from migrating into the cold-aisle space.”
Seaton adds, “If you look at a data center’s entire cooling sys-
tem as an ecosystem, by virtue of maintaining complete isola-
tion between supply air and return air, you can allow the supply
air to be raised in temperature to equal the delivered air temper-
ature. Most want the equipment to see air between 68° and 77°.
To get that temperature, your supply air is typically delivered in
the 52° to 55° range. Follow the line of your cooling system, and
you’ll find the chilled-water temperature coming off the con-
denser is in the low 40s. When you eliminate mixing [of supply
air and return air], you can raise your supply air from 52° to 72°,
in which case the chilled-water temperature can be 60°.”
Adopting the data-center-as-ecosystem concept may be
necessary for managers to achieve the energy efficiencies
put forth in the EPA’s report to Congress. And while cabling
infrastructure, including racks and cabinets, might play only
a small part, the ecosystem mentality dictates that each part
affects others.
Next month, we will delve further into the EPA report and dis-
cuss the activities of The Green Grid, an energy-consumption-
conscious consortium in the IT industry.

To ensure long- term integrity of the system, always use compression con- nectors (not mechanical) so the connection does not loosen with vibration. Once cabling to the patch field has been bonded, atten- tion can be turned to the rest of the bonding and grounding system. Here are several “best practices” that must be con- sidered during the design and installation of the rest of your shielded structured cabling system: Best Practice 1: Grounding the cable shield During installation, a frequently asked question is whether the installer should ground one or both ends of a shielded cable channel. Generally, the cable shield is bonded to the grounded equipment chassis or rack at each access or patch location. In other words, if the IT equipment is grounded, then any shielded cables used to connect equipment to patch panels, or to other equipment, must be grounded. A typical shielded structured cabling channel runs from a switch to the workstation and comprises two patch cord links and the shielded horizontal link. One end of the channel starts in the data center where the switch, patch panel, and shielded patch cord linking them must be properly bonded to the rack. The rack is tied to the telecommunications grounding system, which in turn is bonded to the AC power system. The other end of the channel terminates outside the data _____________________________________ center at the workstation outlet.

The entire project consists of about 8,000 hand terminations. Personally, I would much rather be installing 8,000 anaerobic SCs than 8,000 RJ-45-style UTP connectors. The anaerobic SCs have no worries about separating eight differ- ent color-coded wires during termination, about maintaining this twist or that twist, about punching down too hard or not hard enough, and no worries about extra testing for alien crosstalk—or any other crosstalk for that matter. The technicians used a basic power source and light meter to test their fiber segments to ensure they were within the recommended loss bud- get of the electronics. Only a few SC fiber connectors had to be reterminated. The decision to use 50/125-µm, OM3 laser-optimized fiber also was simple. The user needed a product that would offer a final solution to cabling-upgrade issues that have plagued all information-tech- nology managers since the early days of networking. The ever-increasing demand for more bandwidth, the need for security, ________ and the demand for network reliability made fiber-to-the-desk the best solution.

C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue B Next Page EMaGS F upgrade a fiber network is simply a matter of changing a switch or network interface card. In reality, the formula for fiber-to-the-desk is also simple: Install it, test it, and forget it. Because the active telecommunications room (TR) as we know it goes away, there is no need for heating/ventilation/ air-conditioning (HVAC) equipment, air ducts, primary power, secondary power, secure access, thermostats, lights, uninterruptible power supplies, ground- ing, and switches. Plus, consider that many active TRs consume roughly 2% of a building’s annual power budget. Consider, too, that building space is at a premium; the TR is much smaller when fiber-to-the-desk is deployed. Weighing the real-estate and TR-re- lated issues above, fiber-to-the-desk pro- vides a cost-effective solution ready for future applications, with almost lim- itless bandwidth capabilities. Also, if there was any doubt about whether one is getting full network speed to the desk continuously, fiber provides a comfort level that copper does not. Yesterday and tomorrow While contemplating the need for a fiber-to-the-desk solution, the court division not only considered the ever-changing bandwidth demands of the present, but also those of the future. Over the years, they had installed several generations of UTP cabling, and believed the time had come to install a longer-term solution. With an eye to the future, they decided to specify the latest OM3, 50/125-µm laser-optimized multimode fiber to be used through- out the system at all U.S. federal court house locations in Houston, McAllen, Laredo, Victoria, Corpus Christi, Brownsville, and Galveston.

Although fusion splicers were used for splicing pigtails to the 144-fiber backbone cable serving every TR, this entire project is otherwise being completed with basic fiber- optic tools and test equipment. The loss budget for the low-cost, high-performance 1300-nm media converters used at each end of the fiber segments is 11 dB. With a 3-dB aging (excess margin) built in at design and additional specified losses allowed for cable, connectors, and splices, no segment is approaching an attenuation level that would cause concern now or in the future. Specifically, the U.S. Courts’ technicians are able to achieve an average splice loss of 0.0 dB and a loss of less than 0.3 dB per connector pair using the anaerobic three-step polishing process. Testing of the newly installed fiber segments is being accomplished with an optical-loss test set.

Today, that’s often the case. “It used to be that when I would go to a customer, I would talk to the IT personnel,” Villa says. “Today, I talk to facilities personnel—plumbing, electri- cians, and others. Everyone is on the same page much earlier in the process than in the past.” Marc Naese, solutions development manager with Panduit (www.panduit.com), says, “Overall, we see four critical areas of the data center: the entire infrastructure, network compo- nents, storage components, and computing resources. All four areas must interoperate.” Naese adds, “We have developed our solutions to address specific issues in each of those areas. On a room level, cooling supports the entire ecosystem. As you get down to a rack or cabinet level, the needs change drastically. Side-to-side versus front-to-back airflow is an example.” Naese concludes, “Before you can understand your power or cooling requirements, you must know how many servers you are going to deploy. From there, you can calculate what your requirements will be, what the cabinets will look like, and how dense those cabinets will be.” Keep them separated Ian Seaton, technology marketing manager with Chatsworth Products Inc. (www.chatsworth.com), points out, “When you follow industry understanding of best practices, everything that is done in the data center is really designed to separate the supply air from the return air as much as possible. That’s why, he explains, the hot-aisle/cold-aisle setup was established: “It’s why you seal off access cutouts, install blank tiles, and locate your cooling units in the hot aisles so you prevent your return- air path from migrating into the cold-aisle space.” Seaton adds, “If you look at a data center’s entire cooling sys- tem as an ecosystem, by virtue of maintaining complete isola- tion between supply air and return air, you can allow the supply air to be raised in temperature to equal the delivered air temper- ature. Most want the equipment to see air between 68° and 77°. To get that temperature, your supply air is typically delivered in the 52° to 55° range. Follow the line of your cooling system, and you’ll find the chilled-water temperature coming off the con- denser is in the low 40s. When you eliminate mixing [of supply air and return air], you can raise your supply air from 52° to 72°, in which case the chilled-water temperature can be 60°.” Adopting the data-center-as-ecosystem concept may be necessary for managers to achieve the energy efficiencies put forth in the EPA’s report to Congress. And while cabling infrastructure, including racks and cabinets, might play only a small part, the ecosystem mentality dictates that each part affects others. Next month, we will delve further into the EPA report and dis- cuss the activities of The Green Grid, an energy-consumption- conscious consortium in the IT industry. 36 ■ November 2007 ■ Cabling Installation & Maintenance www.cablinginstall.com C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue B Next Page EMaGS F

The LANmark-6 OSP (outside plant) cable includes a water-blocking gel compound within the core that encases the four UTP copper pairs and a flexi- ble, black polyolefin, UV-resistant jacket. With a total outside diameter of .250 inches, the cable is designed to support such facilities as portable classrooms, detached garages, guard shacks, and other wet locations. The cable is also suit- able for exterior security cameras. This NEC and TIA/EIA-568.B.2-1-compli- ant cable can provide data, video, and power on all four pairs through Power over Ethernet capabilities.

Some of today’s highest-end users already implement 10GbE in the various optical forms in which it is available today. Many more are watching closely as network- gear makers build 10GBase-T—10-GbE’s copper iteration—capabilities into what have been promised as cost-effective alternatives to optical systems. For professionals in the cabling industry, the tenfold upgrade from gigabit speeds to 10GbE is proving far more complex than the transition that brought them from 100 Meg to 1 Gig. Terms such as mitigation, augmented, and of course alien crosstalk now are part of the everyday lexicon for cabling-system professionals who are exploring the practicalities of implementing 10GBase-T. The 10-Gig Testing Resource Center, sponsored by Agilent Technologies, is designed to be a useful tool to help designers, installers, and users of these ultra-high-speed cabling systems in that endeavor. The Resource Center includes selected articles and stories from the pages of Cabling Installation & Maintenance magazine and its Website, as well as resource materials made _____ available by Agilent.
