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.
6. The fans must be running. If not, check the installation of the CURL.
7. Reconnect the power cord to the power unit in the “B” carrier.
8. At the power distribution unit, set the main circuit breaker to OFF.
Install Circuit Packs
1. Install the new control circuit packs into carriers “A” and “B.”
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 directly-connected critical reliability 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.
Interconnect Port Networks
You must next install all the fiber optic cabling and then administer it. For the
installation procedure, refer to
