Do not connect the power cable without powering off the device. 

 

Do not supply power for the device before installing the device or connecting cables. 

 

Confirm that the grounding cable is connected properly. 

 

  Insert positive and negative poles of 

the  power  cable  into  holes  of  the  plug 
and  then  tighten  screws.  (Do  not 
mismatch  the  positive  and  negative 
poles.) 

  Insert the plug into the socket on the 

front panel of the power card and tighten 
screws  to  fasten  the  plug  on  the  power 
card. (The power card is inserted into the 
chassis.)

Method 

Components are installed properly without loose ends or shedding phenomenon. 

View. 

Screws are tightened. 

View. 

Cables are correctly connected without loose ends or shedding phenomenon. 

View. 

The wiring of cables should meet design requirements. 

View. 

No damage, breakage, or middle connector for signal cables 

View. 

Protective measures are taken over pigtail fiber laid outside of the cabinet, such as 
equipping them with sheaths or channels. 

View. 

The radius of curvature of an optical fiber should be 20 times greater than the diameter. 
In general, it should be greater than 40 mm. 

View. 

Labels on both ends of the signal cable should be correct, distinct, and neat. 

View. 

Power cables and grounding cables are connected correctly and reliably. 

View.

The power cable and grounding cable should comply with engineering design documents 
and facilitate expand capacity. 

View. 

11 

Power cables and signal cables are laid separately. 

View.

No fingerprints, stains, or scratches on the surface of the device 

View. 

13 

Use a multimeter to detect the DC power supply. And ensure the voltage of the DC power 
supply ranges between -40 V and -57 V. 

Use a multimeter. 

14 

The fuse is big enough so that the device works properly under the maximum power 
consumption. 

View. 

15 

Mesure the grounding resistance of the grounding cable and grounding terminal of the 
chassis. Ensure the grounding resistance is not greater than 1Ω. 

Use a multimeter.
