Table 1–1 Diagnostic Flow for Power Problems
Symptom Action
System does not power on.
• Check the power source and power cord.
• Check that the system’s top cover is properly
secured. A safety interlock switch shuts off power
to the system if the top cover is removed.
• If there are two power supplies, make sure both
power supplies are plugged in.
• Check the On/Off switch setting on the operator
control panel.
• Check that the ambient room temperature is
within environmental specifications (10–40°C,
50–104°F).
• Check that internal power supply cables are
plugged in at both the power supply and system
motherboard (Section 5.9).
Power supply shuts down after a
few seconds (fan failure).
Using a flashlight, look through the front (to the left
of the internal StorageWorks shelf) to determine if the
fans are spinning at power-up. A failure of either fan
causes the system to shut down after a few seconds.
