The position for each device conforms to the engineering drawing and meets
clearance requirements. Sufficient space is reserved for equipment maintenance.
The BBU, RRUs, and auxiliary devices are securely installed, and all screws are
tightened.
The DIP switch on the BBU is correctly set.
The cover plate is securely installed on the RRU cabling cavity.
None of power cables and PGND cables are short-circuited or reversely connected.
In addition, these cables are not damaged or broken.
There are no connectors or joints on each power cable or PGND cable.
The terminals at both ends of the power cable or PGND cable are securely soldered
or crimped.
Bare wires and OT terminals at the wiring terminals are tightly wrapped with
insulation tapes or heat shrink tubing.
The work grounding and protection grounding of the base station share one group
of ground bodies with the surge protection grounding of the building.
The connectors of each signal cable are intact, and these cables are not damaged
or broken.
The distance between the bundled fibers and the BBU panel is between 40 mm
(1.57 in.) and 70 mm (2.76 in.). This avoids the interference by the cover plate of
the IMB03.
Labels are correct, legible, and complete at both ends of each cable.
