CAUTION:
The removal of hardware and fiber cable will interrupt service.
NOTE:
At this point in the downgrade procedure, the system is in unduplicated
mode and is operational. The physical removal of the SN carriers may be
done at a time that is convenient for the customer. The next step in the
downgrade is to follow the normal upgrade procedures from standard to
high reliability.
5. change fiber n Change fiber removes the b-pnc endpoints
(EI, DS1Cs, if equipped). n is the number of
the fiber from step 4. Repeat this step for
every fiber from step 4.
6. Physically remove the b-pnc
endpoint circuit packs
Start with the switch carrier most distant
from the media server. Physically remove
EI, SNI, and SNC circuit packs associated
with the b-pnc.
Remove fiber cable not used for b-pnc
carriers. See the following CAUTION.
7. change circuit pack Update the translations for the removed
circuit packs using the change circuit pack
command for the:
■ Cabinet with b-pnc SN carrier
— SNIs
— SNCs
— EIs and DS1Cs, if any
■ Cabinet with b-pnc SN carrier
— DS1Cs from port carrier
■ Cabinet with b-pnc EIs in every PN
(also DS1Cs, if equipped)
8. change cabinet UUC Remove the b-pnc SN carrier.
9. Disable duplication. Obtain a license file to disable PNC
duplication.
