(Optional) Installing a Cable Management Strip and a Protective Unit

(Optional) Installing a Cable Management Strip and a Protective Unit

Context

If unshielded network cables are used as E&M trunk cables and need to be lead outdoors, install a cable management strip on the cabinet and install protective units on the cable management strip.

Tools and Accessories

  • Impact tool
  • Diagonal pliers
  • Phillips screwdriver
  • Cable management strip holder
  • Cable management strip
  • Protective units
  • M6 screws
NOTE:

The cable management strip holder, cable management strip, protective units, and M6 screws are not included in the installation accessory package delivered with a card and need to be purchased separately.

Procedure

  1. Use a Phillips screwdriver and M6 screws to fix the cable management strip holder onto mounting rails of the cabinet, as shown in Figure 5-6.

  2. Put the unshielded network cable connected to the local device through the cable inlet at one side of the cable management strip holder, and put the unshielded network cable connected to the remote device through the cable inlet at the other side of the cable management strip holder. See Figure 5-7.

  3. Connect the unshielded network cables to a cable management strip.

    NOTE:

    The following describes connection of one unshielded network cable. Connect all the unshielded network cables in the same way.

    1. Use a pair of diagonal pliers to strip off about 15 cm of insulation coating of the unshielded network cable.
    2. Divide the four twisted pairs of the cable into eight wires and arrange them orderly.
    3. At the local device side, put each two wires through a pair of wire dividers at the left side of the cable management strip and lead the wires into the wire slots at the left side. At the remote device side, put each two wires through a pair of wire dividers at the right side of the cable management strip and lead the wires into the wire slots at the right side. See Figure 5-8

      The two wires in the same wire slot on the cable management strip must be the same color.

    4. Use an impact tool to push the wires into the wire slots. Press a wire with the impact tool until you hear a click, as shown in Figure 5-9.

    5. Install a protective unit on each wire slot with wires connected. Keep a protective unit vertical with a wire slot (with the diode of the protective unit facing the arrowhead on the wire slot), and insert the protective unit until it is completely in the wire slot, as shown in Figure 5-10.

    6. Install the cable management strip onto the cable management strip holder, making the end with a shorter hook face up and the end with longer hook face down, as shown in Figure 5-11. Gently shake the cable management strip. If the cable management strip is still fixed on the holder, it is installed properly.
