Installing and Routing cables  

Installing and Routing Power Cables 

 Downward Cabling 

 

 

Do not install or demount the power cable while the power is on. To avoid personal injuries, turn off the power 
before performing the operations. 

The signal cable, power cable and fiber should be routed and bundled separately. Connect these cables in 
sequence: PGND cable > BGND power cables > -48 V power cables. 

When the power cables are routed downward, the number of cables respectively routed on the two sides of 
the cabinet should be the same. See the previous figure.
