Test the CURL
1. Plug the cabinet power cord into the appropriate receptacle.
2. At the power distribution unit, set the main circuit breaker to ON.
3. Unplug the power cord from the power unit “B” (right-hand side) in the “A”
carrier.
4. The fans must be running. If not, check the installation of the CURL.
5. Reconnect the power cord to the power unit in the “A” carrier, then unplug
the power cord from power unit “B” (right-hand side) in the “B” carrier.

Install Circuit Packs
1. Install the new Release 8 control circuit packs into carriers “A” and “B.”
Use the new decal and the annotated “list configuration all” (provided with
the Release 8 translation card) as a guide.
NOTE:
Currently, both TN768 Tone Clock circuit packs reside in port slots of
the universal module being upgraded. As part of this step, relocate
these circuit packs to the “TONE CLOCK” slot of carrier “A” and port
slot “1” of carrier “B.”
2. For a directly-connected critical reliability Release 8 system with 2 port
networks, ensure that the PPN and this EPN are both equipped with 2
TN776 or TN570 Expansion Interface circuit packs.
For a directly-connected system with 3 port networks, ensure that the PPN
and each EPN have 4 TN776s or TN570s.
