Caution:
A system with DS0A links cannot run without a composite clock source.
Take extreme caution when replacing the ACLK to extension shelf
cables. Remove one cable at a time and confirm between removal that
the other composite clock source on that shelf is active.
Start adding the secondary HS clock cable the cable (P/N 830‑0873‑xx) and

adapter (P/N 830‑0846‑01) on the control shelf by removing the cable end at
ACLK4 connector J56.
At the terminal, the EAGLE displays alarms indicating loss of ACLK to cards on
shelves 5100, 5200, and 5300 and BCLK normal.
Generate a clock status report to confirm that cards on shelves 5100, 5200, and
18.
5300 are using the BCLK. Enter the following command:
rept-stat-clk
The output indicates whether the BITS clock is running again. In this example, the
primary BITS clock is active and the secondary BITS clock has failed.

If cards on shelves 5100, 5200, and 5300 indicate bad ACLK and BCLK,
reconnect the ACLK3 cable to connector J57 and abort this procedure.
