To cable the output to the cable plant, complete the following steps.
Install the output cables in the header blocks. Start with the header block on the far right (1H—1A). For
Step 1
easier troubleshooting, use the same color sequence that was used for CMTS cabling.
A–red, B–white, C–blue, D–green. H–yellow, I–violet, J–orange, K–black.
Run the output cables (H–A) from header blocks to splitters, US laser receivers, or the low side of the
