  • Page 87 Table6-4 Information on labels affixed to DC power cords Content Meaning • Loaded cabinet side—Only MN is used to identify the cabinet number (row MN(BC)-–48Vn number and column number in the equipment room). MN(BC)-RTN • Power cabinet side—MN identifies the row and column number of the power distribution equipment like the control cabinet and distribution box.
  • Page 88 Engineering labels for AC power cords These labels are affixed to the AC cables that provide power for cabinets and protection grounding cables, including POWER, RTN, and PGND cables. The 220 VAC cables and related PGND and RTN cables are covered with insulating sheath, so the labels only need to contain "AC" and the cabinet number.

    Appendix B Cable management General cabling requirements Minimum curvature radius of cables • Attached power cord, communication cable, or ribbon cable—A minimum of five times the cable’s outer diameter. If the cable is frequently bent, connected and removed, the curvature radius must be a minimum of seven times the cable's outer diameter.
  • Page 91 • Route different types of cables (power cords and signal cables for example) separately. If they are close to one another, cross them over one another. If you route them in parallel, keep a minimum distance of 30 mm (1.18 in) between a power cord bundle and a signal cable bundle. •...

    • Cables must be protected at points where they might rub or come in contact with sharp edges or heated areas. Use high temperature cables near heat sources. • Securely fasten cables and take adequate measures to prevent loose connections.

Do not place them at a location out of the cabinet and easy to reach. The power supplies of the router are located along the left and right edges of the rear panel. As a best practice, route power cords as shown in Figure7-6.

    Appendix C Repacking the router This chapter describes how to repack the router chassis, power supplies, and modules. Removing cables from the router Before repacking the router, remove all cables such as the power cords, console cable, twisted pair cables, optical fibers, and grounding cable from the router. Removing the power cords Switch off the circuit breakers at the input end of all power cords.
