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
