Installing and grounding the main drop cable
Perform this procedure to install the main drop cable, connect it to the ODU, and
ground it to the supporting structure.
To install and ground the main drop cable, proceed as follows:
1 Hoist the main drop cable up to the ODU using the hoisting grip and a
hoist line. When the cable is in position and the grip handle is fastened to
the supporting structure, remove the hoist line.
2 Connect the top end of the long drop cable to the ODU (PoE port), as
described in
Connecting an RJ45 and gland to a unit on page 5-19 .
3 Lay the main drop cable as far as the building entry point, ensuring there
is enough length to extend through the wall of the building to the LPU.
4
Attach the main drop cable to the supporting structure using cable ties
or cleats.
5 Ground the drop cable to the supporting structure at the points shown in
Figure 2-3 (mast or tower installation) or Figure 2-4 (wall installation), as
described in Making a drop cable ground point on page 5-22 .
NOTE
A mast or tower may require additional grounding points, as
specified in
Protection requirements for a mast or tower installation
on page 2-14 .
