host is seated firmly in the card cage.

❐ Verify the boot jumper setting if the DMC is installed (see page 10-9).
❐ Be sure the system is not overheating.
❐ Check the cables and connectors to be certain they are secure.
❐ Check your power supply for proper DC voltages. If possible, use an oscilloscope to look

for excessive power supply ripple or noise (over 50 mV

below 10 MHz).
