approximately 0.6 cm (0.25 inch).
b. Slide the power supply out of the bay and set it aside.
DANGER
Electrical voltage and current from power cables are hazardous. To avoid a shock hazard,
always place electrical equipment on dry, static-free level surfaces. Never turn on any electrical
equipment when there is evidence of fire, water, or structural damage.
11. Place the replacement power supply on a dry, static-free level surface.
12. Make sure that the release levers on the power supply are in the open position.
13. Slide the power supply into the bay until it stops.
14. Push the release levers to the closed position.
15. Connect the power cord and turn on the power.
16. Check the power and fault LEDs on the new unit.
17. According to the status of the power and fault LEDs, use one of the following procedures:
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 18.
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 19.
18. Perform the following task or tasks to solve the problem:
v Make sure that the power switch is turned to the on position.
v Make sure that there is power at the ac outlet and no circuit breaker has tripped.
v Make sure 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.
19. Complete any remaining Recovery Guru procedures, if needed.
