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

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.
