the cards!
Procedure
1. If necessary carry out the preparations as described in the Chapter "System
Upgrade 2065", page 959.

connect the PBX and any external Auxiliary Terminal Power Supply (ATPS)
from the 230 V mains.
3. Remove the PBX cover.
4. Unscrew the screws on the screening strip and pull out the processor card
complete with screening strip.
5. Press the side locks on the RAM card outwards and pull out the RAM card (see

notches on the RAM card prevent it from being inserted incorrectly.
7. Press the side locks inwards until they click into place.
8. Wrap the RAM card in the ESD protective sleeve.

of the metal cage and that the ends of the screening strip are flush against
the edge of the metal cage once the card has been inserted.
10. Screw the screening strip to the metal cage using the 2 screws.
11. Fit the housing cover.
