910 Hardware updates and system expansion Part 7
3.3.2 Processor card MPC-8260
The MPC-8260 processor card for the 2065 basic system is factory-fitted in a spe-
cial system slot and cannot be moved to a different slot. The processor card is
replaced together with the mainboard and therefore does not have to be
removed separately.
On the 2025 / 2045 basic system the processor is integrated into the mainboard.
3.4 Mainboard and power supply modules
This chapter describes when and how mainboards and power supply modules are
replaced.
3.4.1 Replacing the 2025 / 2045 or 2065 mainboard
If the mainboard or one of the system cards is defective or permanently faulty, the
entire basic system will have to be replaced, complete with system cards and
metal housing.
1. If still possible, save the configuration data using AIMS.
2. Switch off the PBX. If using a UPS, first disconnect the batteries and then pull
out the mains plug.
3. Remove the PBX cover.
4. Touch the earthed housing of the PBX (equipotential bonding).
5. Remove the expansion cards and UPS module. For details of the procedure for
removing expansion cards, see "Replacing a defective card", page 906.
6. Replace the EIM card of the defective mainboard and the new mainboard. See
"EIM card", page 901 for the procedure.
7. Dismantle all the connected cables in such a way that the new basic system
can be identically reconnected.
8. The mainboard is not dismantled but replaced complete with metal housing.
Depending on the installation (wall-mounting / cabinet mounting) the hous-
ing with the mainboard may also have to be dismantled and the housing
cover screwed back on.
9. The new basic system can now be reassembled and fitted in the reverse
sequence.
