4-5 Completing the Link CX Installation
The Link CX and associated antenna are now mounted on the pole, and coarse-aligned with the far-end
antenna. Continue with the following steps to complete the Link CX installation.
4-5.1 Mounting the Lightning Arrestor
interWAVE 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.
47 Install the lightning arrestor according to the manufacturers instructions, and according to
the guidelines in Appendix 4 to lessen the chance of damage from lightning strikes.
4-5.2 Routing the Data and Power Cables from the Lightning Arrestor
48 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.
49 Connect the power, DS-3 and/or Ethernet cables to the power, DS-3 and/or Ethernet equip-
ment and the lightning arrestor.
50 Route power, DS-3 and/or Ethernet cables from the lightning arrestor to the Link CX.
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 and the lightning arrestor. Avoid tight bends during cable routing and
fastening.
51 Connect the power, DS-3 and/or Ethernet cables to the lightning arrestor.
52 Connect the power, DS-3 and/or Ethernet cables to the Link CX. See Figure 4-1 and
Table 4-1 for the locations and descriptions of the Link CX connectors.
53 Check the LEDs for proper operation. See Figure 4-1 and Table 4-1 for the locations and
descriptions of the Link CX LEDs.
When power is properly applied to the Link CX, the PWR/LCL ALARM LED will be on.
The Link CX 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 to prevent broadcast
storms.
When you apply power to the Link CX, it starts transmitting. Do not
stand within 2 m (79 in.) of the front of the antenna during Link CX
operation to avoid harmful RF radiation.
