SI Installation and Upgrades
June 2004
NOTE:
The new R8si control carrier has only 1 more port slot than a J58890AB control carrier.
You may need to move and retranslate circuit packs. If it was not done before the upgrade,
relocate the circuit packs now. The relocated port circuits will have to be translated after
the system is rebooted with the R8si translation memory card.
3
Install circuit-pack blanks in slots not equipped with circuit packs.
