2.13 Completing the Link CX-24 Installation

The Link CX-24 is now mounted on the pole, and coarse-aligned with the far-end antenna. Continue with
the following steps to complete the Link CX-24 installation.

2.13.1 Mounting the Lightning Arrestor

31

Install a lightning arrestor according to the manufacturer’s instructions, and according to the
guidelines in Appendix D to lessen the chance of damage from lightning strikes.

Note:

YDI strongly recommends that you use a lightning arrestor, such as the Transtector Lightning
Arrestor Kit, at the cable entry to the power, DS-3 and/or Ethernet equipment structure.

2.13.2 Routing the Data and Power Cables from the Lightning Arrestor

32 Route cables from the lightning arrestor through the cable entry to the power, DS-3 and/ or Ethernet

equipment. Leave a minimum of 38 cm (15 inches) of service loop in the cables where they attach to
the lightning arrestor. Avoid tight bends during cable routing and fastening.

33 Connect the power, DS-3 and/or Ethernet cables to the power, DS-3 and/or Ethernet equipment and

the lightning arrestor.

34 Route power, DS-3 and/or Ethernet cables from the lightning arrestor to the Link CX-24. Using cable

ties and/or standoffs, fasten these cables to the structure at 3 m (10 ft.) intervals. Leave a minimum of
38 cm (15 inches) of service loop in the cables where they attach to the Link CX-24 and the lightning
arrestor. Avoid tight bends during cable routing and fastening.

The Link CX-24 has two Ethernet ports, and includes and internal Ethernet switch. However, typical
Ethernet hubs and switches do not have spanning tree capability. MAKE SURE that you make only ONE
Ethernet connection from a hub or switch to the Link CX-24 to prevent broadcast storms.

35 Connect the power, DS-3 and/or Ethernet cables to the lightning arrestor. When you apply power to
