Symptom Action
System does not power on. • Check the power source and power cord.
• Check the On/Off setting on the operator
control panel. Toggle the On/Off button to
off, then back to the On position to clear a
remote power disable.
• Check the indicator lights on the operator
control panel. If the green Power OK light is
off and amber Halt/Remote Power Off light is
on, the system may be powered off by one of
the following:
− a remote management console command
− system software
− fan failure
− overtemperature condition
− power supply failure
− power select switch on power supply is
set to 120V for a 220V power source
• 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 the system motherboard.
Power supply shuts down after
a few seconds (fan failure).
Listen to hear if the fan is spinning at power-up. A
failure of the fan causes the system to shut down
after a few seconds.
Enter the remote management console and query
system status/alerts (using the status command)
for an indication of fan failure or overtemperature
condition. Refer to Chapter 4 for instructions.
