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
15. Are switch settings correct?
If YES, then do TAP-103.
If NO, then continue with Step 16.
16. Use sw-sync: command to switch to other circuit pack before removing pack.
Change switch settings to the correct settings. 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.
17. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
18. Have two of the same type (service and protection TGS, TG3, MXRVO,
STS1E, DS3, or TMUX) circuit packs been removed from the system?
If YES, then continue with Step 19.
If NO, then do TAP-108.
19. 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 pushbutton on the
SYSCTL. If the circuit pack is not to be reinserted, momentarily depress the
UPD/INIT button on the SYSCTL to remove the circuit pack from the inventory.
20. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
