Genesis MP24 ◆
9. Replace nPOWER card.
10. Replace motherboard.
In the event the Genesis MP starts to power up, but shuts down
shortly after the boot sound is heard:
1. 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.
2. Reset the CUDA Chip (see section CUDA Chip in this chapter).
3. Ensure proper voltage is being supplied by the power supply
(see Appendix C - Voltage Readings). If voltage is out of
spec, replace power supply.
4. Check the voltage of the battery (see Appendix C - Voltage
Readings). If the battery is not providing sufficient voltage, replace it.
5. Disconnect SCSI devices.
6.
Remove and test the cache DIMM. (If present in the 3 slot Genesis MP)
7. Remove all PCI cards.
8. Remove the nPOWER card and disconnect the 3.3v connector
from the motherboard. If the power supply and the dual fans
power on, then replace the motherboard.
9. Replace the power supply.
10. Replace the nPOWER card.
Error Chords
In the event a one-part error chord sounds during the startup
sequence, perform the following procedures:
1. Disconnect the SCSI data cable from the hard drive and restart
the system. If the startup sequence is normal, update or replace
SCSI driver. Then initialize the hard drive as a last resort. Test
the unit again with the SCSI data cable connected. If the error
chord still sounds, troubleshoot with another drive which is oper-
able. If this drive operates effectively, replace the hard drive.
2. Disconnect the floppy drive cable and restart the system. If the
startup sequence is normal, replace the floppy drive.
3. Reseat the nPOWER card, the Video card, all DIMMs, and the
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.
4. Test with operable DIMMs.
5.
Remove and test the cache DIMM. (If present in the 3 slot Genesis MP)
6. Replace nPOWER card.
7. Replace motherboard.
