Typical deployment
A PTP 670 site typically consists of a high supporting structure such as a mast, tower or building for the
outdoor equipment (ODU and optional external antenna); and an equipment building or moisture-proof
enclosure for the indoor equipment (PSU), as shown here in a typical mast or tower installation:
Note
These instructions assume that LPUs are being installed from the LPU and grounding kit
(Cambium part number C000065L007A). If the installation does not require LPUs, adapt these
instructions as appropriate.
If LPUs are being installed, only use the five black-capped EMC cable glands supplied in the
LPU and grounding kit. The silver-capped cable glands supplied in the ODU kits must only be
used in PTP 670 installations which do not require LPUs.
