Table 9-6 lists the check items of the signal cable connection. 

 Checklist for the signal cable connection 

1 

The connectors of the signal cables must securely connected. 

2 

The connectors of the signal cables are intact. 

3 

The signal cables are intact. 

4 

The cable ties are evenly spaced. The signal cables are bound neatly with cable 
ties to proper tightness, and arranged at even intervals in the same direction. 

5 

The extra length of the cable ties is cut and removed. The cut surfaces of the 
indoor cables are smooth and have no sharp edges. 

6 

The cable layout facilitates maintenance and expansion. 

7 

Correct and clear labels are attached to both ends of the signal cables. 

 

Table 9-7 lists the checking items for other cable connections. 

 Checklist for other cable connections 

1 

The connectors of the other cables must securely connected. 

2 

Labels on the cables are legible and bound based on the engineering 
requirements. The cables must be bound tightly and neatly. The sheaths of the 
cables must not be damaged. 

3 

Positions for routing the cables must meet requirements of the engineering 
design. 

4 

There are no connectors or joints on each PGND cable. None of PGND cables 
can be short-circuited or reversely connected. In addition, these cables are not 
damaged or broken. 

5 

PGND cables are separately bound from other cables. 

6 

The protection grounding of the pRRU and the surge protection grounding of 
the building share one group of ground conductors. 

 

This section describes the power-on check on the pRRU after the pRRU hardware is installed 
and checked.
