SYMPTOM
CAUSE
REQUIRED ACTION
Power problem
1. Inspect circuit boards under low-light conditions.
LEDs glow if processor circuits receive voltage.
Fan should be turning. These indications prove
presence of DC from power supply. Still,
voltages or signals may not be normal.
2. Turn on VGM power. Using 20-volt DC setting on
digital voltmeter, measure DC voltages at power
connector pins.
3. Using 2-volt AC setting on digital voltmeter,
measure same DC voltages as above. Any
reading indicates ripple or noise. In that case,
service power supply.
Faulty wiring
Turn off VGM power. Assure that wiring harness
connectors attach and fully seat onto mating
board connectors.
Improper jumper or
DIP switch settings
Verify that circuit board jumpers are set as
intended. Check DIP switch settings.

Faulty circuit boards
Run power-up self-test sequence. Note errors or
failures during tests. Compare LEDs with LED
indicator status charts. Note discrepancies.
CAUTION:
Don’t remove or install any connector while power is turned on. Doing so
will damage circuit boards or hard disk drive, and void warranty.
