7. Re-install the RRCS DTMF PCB, if required.

Note If there are battery straps on the PCB, make sure that they are placed in the “on” position for the processor card(s) to avoid losing your data.

8.Re-insert the processor card(s), reconnect the ribbon cables and MOH connection, if necessary. If an RSIU card is being added, shift the card positions accordingly, add the RSIU PCB in slot 11 and change the ribbon cable to connect the RCTU PCB(s) to the RSIU.

Note any changes needed to accommodate the displaced card, if necessary. If this creates extensive changes, it may be better to upgrade without adding the RSIU, get the system working, and then adjust the card positions to add the RSIU card.

9.Turn the Strata DK system back on and follow the DKAdmin/DKBackup instruction screens for completing the upgrade.
