IBM 9117-MMB, 9179-MHB manual Replacing the power supply

Attention:

vAttach a wrist strap to an unpainted surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.

vWhen using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.

vIf you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted surface of the system for a minimum of 5 seconds.

4.Align the power supply with the power supply bay and slide the power supply into the system until it locks into place.

6.Note the state of the light-emitting diodes (LEDs) on the power supply. For more information, see “Power supply LEDs” on page 8. If the LEDs indicate that the power supply is operating normally, that is, the AC input LED and the DC output LED are on solid (not flashing) and the fault/identify LED is flashing or off, continue to the next step. If not, remove the power supply from the system and repeat the procedure starting with step 4. If, after repeating the procedure, the power supply is not operating normally, contact your service provider.
