Genesis MP Chapter 3 – Troubleshooting Guide

Problem Resolution
Several system problems can be resolved by resetting the CUDA
Chip. By purging the information kept by the CUDA Chip, you can
restart the system with default settings. It sends a constant signal
to the power supply. If this signal is not within the power supply or
Cuda’s specifications, the system will either shutdown or freeze.
Procedure
The procedure for resetting the CUDA Chip is as follows: Shut
down the system. Remove the AC power connector from the back
of the machine. Open the side panel. Locate the red reset button.
Press and hold the reset button for approximately 5 seconds.
Replace side panel and plug power back into the machine. This
procedure resets the CUDA Chip back to its defaults.
Power Supply
In the event the Genesis MP doesn’t power up:
1. Ensure that AC Power, the keyboard and ADB cable are con-
nected properly. Swap keyboard and cables to test.
2. Reseat the nPOWER card, video card, and ROM SIMM (if present).*
*It is possible that the ROM socket will not be populated (ROM
will be soldered to the motherboard) and reseating the ROM
SIMM should be disregarded.
Reseating the ROM SIMM
3. Reset the CUDA Chip (see section CUDA Chip in this chapter).
4. Ensure proper voltage is being supplied by the power supply
(see Appendix C - Voltage Readings). If voltage is out of
spec, replace power supply.
5. Check the voltage of the battery (see Appendix C - Voltage
Readings). If the battery is not providing sufficient voltage, replace it.
6. Disconnect SCSI devices.
7.
Remove and test the cache DIMM. (If present in the 3 slot Genesis MP)
8. Remove all PCI cards.
