CAUTION:
When removing circuit packs ensure that protection switching is
available. Also, remove the circuit pack without the lighted ACTIVE LED
first.
Check switch settings (rtrv-sync: command) on the TGS/TG3 circuit packs
for correct settings. If the circuit pack has been replaced, check if settings are
the same as they were before the circuit pack was replaced. Also check if the
switches are set the same as the companion circuit pack.
Reference: DLP-513
35. Are switch settings correct?
If YES, then do TAP-103.
If NO, then continue with Step 36.
36. Change switch settings to the correct settings. (Use sw-sync: command to
switch to other circuit pack before removing pack.) If switch settings are to be
changed from what they were previously, update the equipment list by
momentarily depressing the UPD/INIT button on the SYSCTL after the circuit
pack is reinstalled.
37. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
38. Indications are that there is an unprotected failure or removal of a MXRVO or
DS3 circuit pack at the far-end associated with the identified OLIU slot at the
near-end. Determine location of the circuit pack(s) from office records or use
the rtrv-crs-( ) commands to trace back through the STS1/VT1.5
cross-connections associated with the identified OLIU slot.
39. If circuit packs are removed, determine the reason the circuit packs were
removed. If the same circuit pack is to be reinserted and no switch settings are
changed, reinstall the circuit pack. If the circuit pack was removed and switch
settings changed, reinstall the circuit pack and momentarily depress the
UPD/INIT button on the SYSCTL or use the upd command. If the circuit pack
is not to be reinserted, momentarily depress the UPD/INIT button on the
SYSCTL or use the upd command to remove the circuit pack from the
inventory.
