Migrating from a DEFINITY Server SI in an SCC to an S8700-Series Media Server with Fiber-PNC
690 Upgrading, Migrating, and Converting Media Servers and Gateways
!
CAUTION:
CAUTION: All active calls that are processed through this PN are dropped when the cabinet
stack is turned off. All trunks and lines within this cabinet stack are out of service
until the cabinet stack is turned on and the media server controls the PN.
Note:
Note: If the system is equipped with power failure transfer (PFT) units that use ground
start trunks, you must install a temporary ground wire to the PFT units. This
ground wire allows units to operate correctly when the cabinet is turned off. The
AUX cable that usually supplies the ground is disconnected.
2. Connect a 10 AWG (#25) (2.6 mm
2
) wire to pin 49 of the connecting block or to pin 49 of the
cable access panel (CAP) on the power-failure transfer panel.
3. Route the opposite end of the wire to an approved ground and connect.
Note:
Note: You can cut over and have the media server control the other PNs at this time.
Only cutover at this time if you are not installing IPSI(s) in the PPN or the
customer wants to minimize out-of-service time. To cutover, go to Enabling
control of the IPSI on page 697.
4. Turn off the cabinets in the SCC1 stack.
5. Remove all circuit packs from the cabinets and place the circuit packs in an antistatic carrier
or bag.
6. Disconnect the cables on the front of the cabinets.
7. Disconnect the following cables on the back of the cabinets.
● CURL - you cannot reuse this cable.
● TDM/LAN - you can reuse this cable.
● ICC-A, ICC-B - you can reuse this cable.
8. Remove all cabinet grounds.
9. Remove the top cabinet.
10. Remove the subsequent cabinets, including control cabinet A and control cabinet B if this
system is a high-reliability or critical-reliability system.
