The procedure for installing an outdoor network cable
on port GE(e) of an RTN 360 is the same as the
procedure described here.
1. Bend radius
For power and PGND cables, ensure a bend radius of at least three times the
cable diameter.
2. Cable binding
•Bind different cables separately, with a minimum distance of 30 mm.
•Bind cables securely and neatly, without damaging the cable jackets.
•Ensure that cable ties face the same direction and are aligned in rows horizontally.
•Cut off the excess of each indoor cable tie but leave a slack of about 5 mm for
each outdoor cable tie. Ensure that all cut surfaces do not have sharp edges.
•After installing cables, attach labels or tags to the two ends of each cable.
3. Safety
•Lay out cables away from sharp objects or jagged walls, or protect cables using
conduit.
•Lay out cables away from heat sources, or add heat-insulation materials between
cables and heat sources.
•At turns or near equipment, allow sufficient slack in the cables and coil them (with
a diameter of about 0.6 meters) for future use.
4. Indoor cable routing
•Route cables into equipment rooms through feeder windows.
•Form drip loops outside feeder windows and ensure a bend radius equal to or
greater than the required minimum bend radius.
•Seek help indoors when routing cables into equipment rooms.
•Waterproof feeder windows.
General requirements
The requirements for indoor cable routing apply if any section of cable will be
routed indoors.
Requirements for laying out cables outdoors
Route cables along the planned path, use outdoor cable ties to bind cables properly
and neatly at intervals of about 1 meter, and cut off the excess of each cable tie
without leaving sharp edges (ensuring a slack of about 5 mm).
Requirements for laying out PGND cables
•Connect PGND cables of co-sited devices to the same ground bar.
•Do not route PGND cables overhead in outdoor scenarios.
•Bind PGND cables separately from outdoor network cables and keep a
certain distance between the bundles.
•Do not add switches or fuses on PGND cables.
Installing sign plate labels
Attach a sign plate label to each cable end. To do so, pass cable
ties through the holes in the label and attach it to one cable end,
about 100 mm to 200 mm away from the connector.
Tighten the cable ties to fix the label on the cable. Then, cut off the excess
of each cable tie, leaving a slack of about 5 mm and no sharp edges.
