Stackable cable-rack spacers convert conventional ladder racks for routing bulk fiber cables or cable bundles. The wiring accessories are offered in 1- and 6-position styles for cable bundles up to 0.8 inch in diameter. The 6-position spacer can be used with the 1-position for greatest ladder rack width use. The units eliminate the pinch points that can occur when heavy bulk cables or large cable bundles are stacked one on top of the other and the potential signal distortion that can result. The initial spacer is attached to the rung of the ladder rack with a standard nylon Pan-Ty cable tie. A dovetail locking mechanism allows additional spacers to be stacked a recommended 5-high for maximum cable capacity. Standard ties can be used to secure the cable to the spacer.

By the Book

Guides to network certification
CNA Certification: Routing Basics for Cisco Certified Network Associates Exam 640-407 delivers what its subtitle promises: more than 500 pages of information that can be used either for test preparation or as an on-the-job reference. Beginning with the Open Systems Interconnection (OSI) model and local-area-network (LAN) technologies, the book moves rapidly through basic types of active LAN equipment and the TCP/IP (transmission control protocol/Internet protocol) protocol. Most of the book covers the application of these concepts to Cisco routers, with two final chapters on extra features of these devices and wide-area-network technologies. All material is advertised as being class-tested in the CCNA Prep Course, and the book includes lab exercises and practice exam questions. Author Robert M. Myhre is a Minneapolis-based consultant and trainer specializing in Cisco and Microsoft networking. This illustrated volume, which also contains a CD-ROM, lists for $49.99.

Network+ Certification offers information on network fundamentals, configuration, management, security, trouble shooting, and other topics covered by the COMPTIA Network+ examination. Beginning with an exam-requirements matrix, the book purports to offer in-depth coverage of every exam objective, including TCP/IP theory and practice. Priced at $49.99, this 500-page hardcover includes chapter-end review questions (with answers), 'study breaks' spread throughout the text, and appendix, glossary, and index. The book's authors, Tim Hoffman, Kostya Ryvkin, and Dave Houde, are all staff members at Alida Connection, a Microsoft Certified Solutions Provider in Nashua, NH. They have co-authored two other books, both about Microsoft Certified Software Engineering.

Although these two volumes focus more on active electronics than physical infrastructure, Network+ Certification does in fact offer extensive coverage of topics of interest to readers of Cabling Installation & Maintenance: the OSI model and networking standards, types of cabling and network architectures, testing and troubleshooting, network installation and administration, and such maintenance topics as electromagnetic and radio-frequency interference and variations in electric line power.
