14 To return an ISTb HLIU in ManB or OffL state to service, type
>RTS FORCE
and press the Enter key.
Note: If you attempted an RTS before performing the RTS FORCE
command on the HLIU, the HLIU will remain in the ISTb state even after
the composite clock is recovered. Refer to step 17 for information on how
to clear an HLIU of ISTb state after the composite clock is recovered.
The following is a description of what happens after you apply the RTS
FORCE command to an HLIU:
If the composite clock
is the preferred clock for the
HLIU,
is not the preferred clock for the
HLIU,
15 Wait 5 min to see if the links become synchronized.
If the links
become synchronized
do not become synchronized
16 For further assistance, contact the personnel responsible for the next level of
support.
17 For HLIUs that remain in ISTb state after the composite clock is recovered,
determine the condition by typing
>QUERYFLT
and pressing the Enter key.
Note: Check for the failed 00S test. A failed 00S test indicates that the
HLIU was in ISTb state when the composite clock failed. If there is no failed
00S test, follow the "Recovering a stuck HLIU" procedure to clear the HLIU
of ISTb state.
18 To clear the HLIU of ISTb condition after the composite clock is recovered,
perform this step and step 19 during a scheduled maintenance interval. To
start clearing, manually busy the HLIU by typing
>BUSY hliu_no
and pressing the Enter key.
