Control shelves with backplane P/N 850‑0330‑06 or ‑07 or later using HS Source and
composite clock cables P/N 830‑0873‑xx or P/N 830‑1189‑xx.
Note:
Replace the existing composite clock cables (P/N 830‑0226‑xx) with RS422
compatible HS Source and composite clock cables P/N 830‑0873‑xx or P/
N 830‑1189‑xx. For control shelves with backplane (P/N 850‑0330‑06 or ‑07 or
later), connect the cables to J48 and J49 (primary and secondary BITS) and
connect the other ends to the site clock sources.
Note:
Control shelf backplane (P/N 850‑0330‑05) cannot be used with the HMUX card
required to implement the Large System feature.
