The extra length of the indoor cable ties is cut, and the cut surfaces are smooth
without sharp edges. The extra length of 3 mm to 5mm of the outdoor cable ties is
reserved when the cable ties are cut.
The idle port that no cable is connected to is properly protected.
The connectors of the RF cables are fixed in position to avoid false connection that
may cause an abnormal voltage standing wave ratio (VSWR).
describes the BBU hardware installation checklist.
Item
All self-made PGND cables are copper-based with the proper wire diameters.
No switch, fuse, or similar object is allowed for the electrical connection of the
grounding system. No short circuit is allowed. Only one OT terminal of the
PGND cable can be connected to each terminal on the ground bar.
The redundant part of the power cable or PGND cable is stripped off rather
than coiled.
The terminals at both ends of the power cable or PGND cable are securely
soldered or crimped.
The bare wires at the terminals and terminal handles are covered with heat-
shrinkable tubes.
The flat washer and spring washer are well mounted on all OT terminals, and
the OT terminals are intact and contact the wiring terminals properly.
All the cables, including those on the bottom of the cabinet, are securely
connected.
The cables are neatly and tightly bound. The cable ties are evenly spaced and
face the same direction.
The power cable, PGND cable, feeder, optical cable, and the E1/T1/FE cable
are bound separately with spacing of more than 30 mm.
The cable layout facilitates maintenance and future capacity expansion, and
the bending radius of the cable meets the requirements.
Legible labels are attached to both ends of all cables.
The extra length of the indoor cable ties is cut, and the cut surfaces are smooth
without sharp edges. The extra length of 3 mm to 5 mm of the outdoor cable
ties is reserved when the cable ties are cut.
The unused ports are properly protected.
