This document summarizes an article about Ray Gendron, who passed away after battling cancer. It discusses how Ray Gendron was instrumental in founding BICSI Cares, an organization that raises money for children's charities. It describes how Ray worked tirelessly at BICSI conferences to encourage donations, often making up challenges to inspire competitive spirits. While he knew thousands at conferences, he always took the time to greet people by name. Ray leaves behind a legacy of helping thousands of children through the money raised for charities due in large part to his efforts.

Every aspect of structured cabling system pathways must be designed to ensure the highest channel performance. Yet today’s familiar pathways and installation methods may not be ade- quate for new cable technologies that accom- modate 10-GbE. The Telecommunications Industry Asso- ciation (TIA; www.tiaonline.org) has yet to update the TIA/EIA-569-B standard to ad- dress the larger cable needed to support 10-GbE. Factors to consider include the larger diameter of the cable, additional bend radius required, and increased weight of cables, such as Augmented Category 6 UTP (Category 6A) and shielded cables (Category 6 FTP, Catego- ry 7 STP). These requirements differ signifi- cantly from those of older cable designs and have a direct bearing on the performance of The effects of larger and heavier cables needed to support 10-Gigabit Ethernet a 10-GbE system. are felt building-wide, from the entrance facility through the telecommunica- tions rooms, pathways and spaces, all the way to the work area.

In many instances, getting access to underfloor systems can only happen after hours, and some- times at a higher labor rate.” Design considerations In 2005, Julie Roy, principal of C2 Consulting (www.csquared- __________ consulting.biz) and contributor to www.bcsreports.com, made _________ a presentation at a BICSI conference about the Telecommu- nications Industry Association’s TIA-942 standard covering data center infrastructure. In her presentation, she discussed considerations that should be made when cabling is placed either overhead or underfloor. Among those considerations are that a raised floor provides more flexible cooling options than does ducted air. Additionally, cabinets and racks should be arranged on raised floors to permit tiles along the front and rear of the racks/cabinets to be lifted. She also pointed out that cable trays suspended from the ceiling provide more flexibility for supporting racks/cabinets of various heights, and for adding and removing cabinets and racks. As a good-practice recommendation, she also pointed out that cable trays can be installed with several layers; a three- layer system would include copper-based communications cable in the bottom layer, fiber-based communications cable in the middle layer, and power cable in the top layer. “Going overhead requires more engineering, because you have to avoid things like fluorescent lighting and sprinkler sys- tems,” states Tony Lookabill, RCDD, national accounts man- ager for GS Metals’ Flextray line of cable tray. While thermal management is one consideration, Cable Management Solutions’ Jette points out, “Management of the cable is highly critical. It is necessary to coordinate to get path- ways into specific places, so coordination of all services is a key ingredient to successful conveyance.” Obstacles to cable conveyance can be anywhere and every- where above a series of racks or enclosures, and as Jette fur- ther notes, thermal management can be an issue there as well: _________________________ www.cable-install.com C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue B Next Page EMaGS F

C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue Next Page EMaGS B F Power cables, like these running underfloor through Cable Manage- ment Solutions’ Power Snake Canyon, should run in the data center’s cold aisle. “I have been in data centers where active cooling componen- try is above each tray, and in data centers where chillers are directly on top of enclosures.” Such arrangements make for challenging designs of cable-conveyance equipment. ____________________ _____________ Inherited space Another reality creating challenges in these environments is the types of buildings in which they reside. “Very often, a data- center user, such as a bank, will buy an old warehouse,” notes Grid Associates’ Green, adding that such spaces provide high ceilings that allow tall raised floors. But, he says, these envi- ronments can also present challenges because the structure was built without a data center’s requirements in mind. “One client of ours bought a 300,000-square-foot warehouse, and the data center is going into a bolt-on,” he explains. “Another data center is in an existing building, and there are all kinds of things to work around.” These workarounds can be accom- plished—and, in fact, are some of the tasks Green’s company is hired to accomplish—but nonetheless they are a fact of life when cable is run overhead. For some data center managers, visual appeal plays a role in deciding whether to go overhead or underfloor. “Some data centers are showplaces, where the owners might take custom- ers or investors through,” says Panduit’s Chaloupka. “Many of them do not want anything above the cabinets for aesthet- ic reasons.” Other reasons can also push users to underfloor cabling. C2’s Roy stated in her presentation that most standalone computer systems are designed for cabling from below. Jette adds, “In the current trends we’re seeing, many users have one pathway for ca- ble above cabinets and one path beneath the floor.” Sometimes, he says, users run only power beneath the floor. Other times, both power and data cabling are beneath a raised floor. When to go under When data cabling does run underneath a raised floor, Cha- loupka points out, “it is important to keep cables in close prox- 40 ■ March 2007 ■ Cabling Installation & Maintenance www.cable-install.com C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue Next Page EMaGS B F

He adds that everything run under a floor, including power cables in the data center’s cold aisles, should be in a tray system up off the floor. “If possible, the different cable types can run in different tray systems,” Lookabill says. An absolute-must in these situations is to run underfloor cable-support structures in the hot aisles of hot-aisle/cold-aisle setups. By doing so, any heat generated by cables will not ad- versely affect the cold air flowing through the cold aisle. Like- wise, when access to the cable is necessary, lifting a tile to gain access will not disrupt the flow of cold air in the cold aisle. As is the case with overhead conveyance, underfloor cable pathways require coordination with other trades. While the Panduit’s Fiber Runner system is appropriate for both fiber-optic and ideal situation might be for nothing else other than cold air high-end copper cabling systems. Among the system’s benefits in running beneath a raised floor, in reality, the pathways for data centers are easy access, bend-radius control, cable-management other utilities frequently reside there as well. capability, and the lay-in trough system’s allowance for technicians to When data center managers get the opportunity to decide minimize or eliminate the need to bundle cable. whether to establish cable pathways overhead or underfloor, they must take several factors into consideration, from build- imity to inlets going into the racks,” he says, “in order to protect ing structure to thermal-management needs and aesthetics. and support cables transitioning up into a cabinet or rack.” The issues are many and can conflict with one another.
