7. To verify that the new Tone-Clock circuit pack can generate clocks for the
system, switch to the new Tone-Clock with
set tone-clock UUC override
,
and execute
test tone-clock UUC
. (In a PPN, the SPE-Select switches
must be in the auto position.)
!
CAUTION:
If the new Tone-Clock circuit pack is not able to generate system
clocks, this procedure becomes destructive. The system will detect a
loss of clock and recover accordingly.
In this case if the Tone-Clock circuit pack being replaced is in the
PPN the system will perform a reset system 2 (cold 2 restart)
automatically. If the Tone-Clock circuit pack being replaced is in an
EPN, the system will reset the EPN (EPN cold restart). After either
type of restart, the faulty Tone-Clock circuit pack will be in standby
mode.
If the new Tone-Clock circuit pack is able to generate system clocks,
there will be no system disruption
.
8. Place several phone calls.
9. After replacing a Tone-Clock circuit pack in an SPE, if the SPE lock
switches were set during the procedure, they should be released.
Additionally, after repairs in an EPN, the
set tone-clock UUC
command
should be used if required to make the preferred Tone-Clock circuit pack
active.
