according to the LED status is as under:
v
The fault LED is lit and the ac and dc power LEDs are off: The new unit
might be installed incorrectly. The power-supply switch might not be
turned on. The power cord connector might not be fully inserted into the
power receptacle or the power-supply ac socket. There might not be any
power to the receptacle that the power supply is connected to. The power
cord might be faulty. Go to step 15.
v
The fault and ac power LEDs are lit but the dc power LED is off: The
power supply is faulty. Turn off the power switch and contact your IBM
technical-support representative for a replacement power supply.
v
The ac and dc power LEDs are lit but the fault LED is off: Go to step 16
on page 103.
15. Perform the following substeps to solve the problem:
v Ensure that the power switch is turned on.
v
Ensure that there is power at the ac outlet and no circuit breaker has
tripped.
v
Ensure that the power cord is working and fully seated into the electrical
receptacle and the power supply ac connector.
v
Reinstall the power supply.
If these tasks do not solve the problem, contact your IBM technical-support
representative.
