Avaya S8100 Series Manual page 761

If you want to cut over and have the S8700-Series Media Server control the existing PNs while
you convert the PPN, you must:
1. Turn off the PPN.
2. Enable the IPSIs from the S8700-Series Media Server.
Do this only if the customer wants to minimize out-of-service time. If the PPN also contains the
switch node carrier, you take the CSS out of service when you turn off the PPN.
This stage affects service to the PPN and thus to the existing DEFINITY server system. The
DEFINITY system is out of service while you replace the circuit packs. This should take no more
than 30 minutes.
Cutting over to S8700-Series Media Server control
Once you convert the PPN and you turn on the power, you want to cut over to the S8700-Series
Media Server. To cut over to the media server, you must enable the IPSIs on the IP Server
Interface (IPSI) System Parameters screen.
This stage affects service momentarily while the CSS comes back up and the calls are load
balanced across the IPSIs throughout the port networks.
Completing the migration
This stage includes verifying the data of the customer and upgrading IPSI firmware, if
necessary. The system generates alarms if the IPSIs do not have the most current firmware or
do not all have the same firmware.
