Crestron CNX-ASBK
Installing CNX-ASBKs into CNX-PAD8s
Operations & Installation Guide - DOC. 8143
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.
