Installing CNX-ASBKs into CNX-PAD8s 

One CNX-ASBK is required for each CNX-PAD8 that is to be daisy-chained. The 
only tools required are a Phillips tip screwdriver and a grounding strap. Follow the 
assembly procedure and illustrations that begin after this paragraph.  

CAUTION:  

The CNX-PAD8s must be opened to install the CNX-ASBK. Observe 

precautions for handling electrostatic sensitive devices (ESDs).  

NOTE:

  To daisy-chain CNX-PAD8s, all of the units must be stacked directly above 

the other. 

NOTE:

  This procedure assumes that one CNX-PAD8 is already rack mounted in a 

network system. If this is a totally new installation, start on step 7 of this procedure. 

1.  If the back panel of the CNX-PAD8 is accessible, remove the rack 

mounting screws. If the back panel is NOT accessible, remove the 
screws and pull CNX-PAD8 partially out of the rack to gain access. 

2.  At the rear of the CNX-PAD8, disconnect the electrical power (4-pin 

Cresnet

 power connector and/or the external power pack). 

3.  Note (or label) the position of each 6-pin RJ-11 network device cable 

and disconnect. 

4.  Note (or label) the position of audio output, audio input loop-through, 

and audio input RCA cables and disconnect each cable. 

5.  Remove the ground wire from the CNX-PAD8 ground screw.
