  • Page 84 Engineering labels for optical fibers These labels are affixed to optical fibers that connect the fiber ports on the cards in a chassis, or connect fiber ports on box-type devices. There are two types of labels for optical fibers: labels for a fiber that connects the fiber ports on two devices, labels for a fiber that connects the device and the optical distribution frame (ODF).
  • Page 85 Content Meaning Example • M—Row number of the rack in the equipment room, in the range of A to Z. • N—Column number of the rack in the MN—Row number and column equipment room, in the range of 01 to 99. number of ODF For example, G01 is the ODF of Row G and Column 01.
  • Page 86 Table 7-4 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 87 Table 7-5 Information on labels affixed to AC power cords Content Meaning MN: Rack number (row number and column number in the equipment room) or the location of the socket where the power is led in. The location of the socket is marked according to onsite situation. If the sockets can be MN-AC identified by row number and column number, they can be numbered following the same rule for the rack number.

  • Page 90 Appendix B Cabling recommendations Routing cables The cable management brackets are installed on the two sides of the service module section. As a best practice, route cables from the left and right sides of the device, as shown in Figure 8-1.
  • Page 91 Routing power cords When you route power cords, take consideration of the layout of the equipment room, including the locations of the power distribution cabinet, AC power receptacles, and lightning protection box. Place all re-connecting facilities, such as receptacles, at the rack bottom (Do not place them at a location out of the rack and easy to reach.) The power modules are located at the left and right sides of the rear panel.
  • Page 92 Figure 8-2 Correct and incorrect cable binding • The cable bend radius at connectors must be a minimum of 5 times the cable diameter, and must be a minimum of twice the cable diameter away from the connectors. • Route different types of cables (for example, power cords and signal cables) separately. If they are close to one another, cross them over one another.
  • Page 93 Figure 8-4 Binding cables where they must be bent • Route, bind, and attach excess cables for easy, safe maintenance activities and correct operations. • Do not tie power cords to slide rails. • When you connect a cable to an articulated part, for example, when you connect a grounding cable to a cabinet door, leave enough slack in cables and make sure they are not stressed from any movement of the part.
  • Page 94 Table 8-1 Tie-binding parameters Cable bundle diameter (mm) Space between bundles (mm) 80 to 150 10 to 30 150 to 200 200 to 300 • Do not tie cables or bundles in a knot. • The metal parts of the crimped cold-pressed terminal blocks (such as air switch) cannot protrude beyond the blocks.

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

    To repack power modules: Prepare the original packing materials, including the anti-static bag, foam cushion, and packing box for a power module. Make sure these packing materials are clean, dry, and not damaged. Remove the power module from the chassis. For more information, see "Replacement procedures."...
