Power Problems
Table 8-3 describes how to troubleshoot the system when there is no power at the
system enclosure.
Table 8-3 Troubleshooting Power Problems
Symptom Action
No AC power Check the power source and power cord.
Check that the system cover is properly secured. An
interlocking sensor switch shuts off power to the system if
the cover is removed.
If there are two power supplies, make sure that both
power supplies are plugged in.
AC power is present, but system does
not power on.
Check the On/Off switch on the operator control panel.
Check that the ambient room temperature is within
environmental specifications (10–40ºC, 50–140ºF).
Check that cable connectors on the system board are
properly connected.
Check that the internal power supply cables are plugged
in at the right place on both the power supply and system
backplane.
Power supply shuts down after
approximately 10 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 startup. Replace the fan that does not spin. If
neither fan spins, check the power supply.
Console Problems
Table 8-4 describes how to troubleshoot the system when, at startup, the console
terminal does not display the startup screen, or the startup screen displays error
messages.
