Removing the processor port network control carrier
To remove the processor port network control carrier(s):
1. Label both ends of all the cables being removed from the control carriers. They can be
reused.
!
CAUTION:
CAUTION: All active calls processed through this PN are dropped when the cabinet is turned
off. All trunks and lines within this cabinet are not operating until the cabinet is
turned on and the media server controls the PN.
Note:
Note: If the system is equipped with Power Failure Transfer (PFT) units using ground
start trunks, you must install a temporary ground wire to the PFT units to allow
them to operate properly when the cabinet is turned off. The AUX cable that
normally supplies the ground is disconnected.
2. Connect a 10 AWG (#25) (2.6 mm
2
) wire to pin 49 of the connecting block associated with
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 to having 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 cut over, go to Enabling
control of the IPSI on page 737.
4. Turn off the cabinet.
5. Disconnect the following cables on the front of carrier A.
● Power
● ATM Fiber (optional)
