the central memory and control point for the 4100U system The provides a card slot for the CPU daughter card the master controller and an optional interface card or RS232 2120 interface card It occupies four inches of space in the CPU and is located to the immediate left of the power supply except for in redundant master configurations order to remove the CPU motherboard the daughter cards and any cable connections on the must be removed first Once the old board is removed and the new board mounted the cards and cable connections must be reattached to the new board in the same locations which they were removed on the old board The replacement procedure should only be after all power is removed from the system Remove power to the system by disconnecting any battery connection at the PDM and then Power and the CPU Bay AC power at the breaker Lower the front door to the CPU bay the Old Motherboard Label and detach the service port and front display ribbon cables from the CPU daughter card is mounted in the right card slot of the CPU motherboard see Figure 1 Remove any daughter cards installed in the two card slots of the CPU motherboard or RS232 2120 Card optional
