5 Installation
WARNING!
Installing a unit usually involves height, electricity, and exposure to RF
(Radio Frequency) energy. To avoid personal injury, follow applicable
national and local safety regulations along with industry best practices.
Also follow the specific guidelines in this document, including
maintaining a sustained exposure separation distance of 50 cm (~20 in)
as described in section 6.3 on page 19.
5.1 INSTALLING THE SM
Procedure 2: Installing the SM
1. While on the ground, before climbing, identify the location for the 600SS surge
suppressor. Select a location on the outside of the subscriber premises at the point
where the Ethernet cable will penetrate the residence or building, and as close to an
existing or planned grounding system (Protective Earth) as possible.
2. Using all safety precautions, climb to the roof or use a lift and select the best location
for SM mounting, dependent on
◦ knowledge of the geographical area
◦ location of towers and APs
◦ the roof type and mounting options
◦ experimentation with a powered SM
The SM must be mounted so as to avoid accidental touch. Typically this means
mounting it at least 4 m (~13 ft) above ground level.
3. Select the type of mounting hardware appropriate for the chosen location.
4. Attach the mounting bracket and radio to the structure.
5. Size a length of Cat-5 Ethernet cable for the run from the SM to the location identified
for the SS surge suppressor.
6. Slip the gland and ring on the Ethernet cable.
NOTE:
The gland and ring must be put on the cable before the cable is
terminated with an RJ-45 connector. An RJ-45 connector will not fit
through the gland and ring.
7. Terminate the Ethernet cable with an RJ-45 connector
8. Connect the Ethernet cable to the SM. Include a splicing loop (extra cable to allow
future repositioning or reconnectorization) and position and secure the Ethernet cable
with UV-resistant wire ties or other locally-approved f fasteners so it forms a drip loop
(so water drips off the cable instead of following the cable to the radio).
