Page 77: Appendix A Engineering Labels
Appendix A Engineering labels Engineering labels are used to identify cables and devices for easy maintenance after installation. There are two types of engineering labels, labels for cables and labels for devices. Labels for cables Cables include signal cables such as network cables and fibers, and power cords such as AC power cords and DC power cords. -

FigureA-2 Label for power cords (1) Cable tie (2) Dividing line on the label Generic labels A generic label is bar-shaped with fixed dimensions. It is applicable to both signal cables and power cords. A mark "TO:" is located at the upper left corner in the right area of the label to identify the peer end of the cable on which the label is affixed. -

Page 90: Assembling A Cable
Appendix B Cable assembling and management This section describes attaching cable connectors (ring terminal or RJ connector) to cables. Connectors, cables, and tools to use might vary by vendor. Figures in this section are for illustration only. Assembling a cable Use professional tools and devices and follow the correct steps when you attach a cable connector to a cable. -
Page 91: Attaching A Ring Terminal
When you attach a connector to a cable, follow these restrictions and guidelines: • After crimping, make sure the connector and cable are tightly bonded. • Make sure the cable conductor is not exposed, and cut off the exposed conductor in time. •... - Page 92 FigureB-3 Attaching the ring terminal Use a crimping tool to crimp the tail of the ring terminal. The shape of the end face after crimping varies by crimping tool. FigureB-4 Crimping the ring terminal Cover the joint with the heat-shrink tubing. FigureB-5 Covering the joint with the heat-shrink tubing (1) Crimping section Use a blow dryer to heat the tubing until the tubing closely covers the cable.

Clean the pins again by using lint-free cotton. If necessary, clean the pins by using an air gun. Ensure that the pins are free from any fiber or debris. To clean a fiber connector with guide pins: Fold a piece of lint-free cotton and dip it in alcohol. Then, use the cotton to clean the pins. Clean the pins again by using a new piece of lint-free cotton without alcohol. - Page 105 • Use the correct ties to bind the cables. Do not bind cables with joined ties. • The distances between cable ties must be three to four times of the cable diameter. • Bind and route the cables neatly inside the rack, and make sure the cables are not kinked or bent.

Page 106: Cable Management
FigureB-32 Cutting the cable ties • Route, bind, and attach excess cables for easy, safe maintenance activities and proper operations. • Do not tie the power cords to the slide rails. • When you connect a cable to an articulated part, for example, when you connect a grounding cable to a rack door, leave enough slack in cables and make sure they are not stressed from any movement of the part. - Page 107 Optical fiber management CAUTION: The core of optical fibers is thin and fragile. Do not use cable ties to bind the optical fibers. Use soft binding tapes to carefully bind optical fibers. Avoid excessive force. For more information, see the binding tape use instructions.
