the primary and secondary HS clock cables from the customer's high‑speed clock
sources to the EAGLE control shelf backplane near connectors J57 and J56.
Note:
Route but do not connect the new cables to the backpanel at this time to avoid
any accidental pull on cable connectors that could disconnect them from the
composite clock source. Always route clock cables on separate cable racks, if
provided, for redundancy.
Ensure that each tie‑wrap strap is cut flush with the tie‑wrap head so that no sharp edges
are exposed.
Prepare the open end of the new primary high‑speed source and composite clock cable

(P/N 830‑0873‑xx or P/N 830‑1189‑xx) for connection to the customer's primary clock
and high‑speed clock sources. Remove the outer insulation to expose the wires.
