Figure 25. Expansion unit ac power and OCA power LEDs

10.Note the state of the green ac power in (A) and Offline Converter Assembly (OCA) power (B) light-emitting diodes (LEDs) shown in Figure 25, and do one of the following actions, as applicable:

vIf the LEDs indicate that the power supply is operating normally, that is, that the ac power in LED

(A)is on solid and the OCA power (B) LED is on solid or flashing, continue to the next step.

vIf not, remove the power supply from the expansion unit and repeat the procedure starting with step 6 on page 22. If, after repeating the procedure, the power supply is not operating normally, contact your service provider.

Note: If you replaced a power supply fan as part of this procedure, note the state of the fan fault LED (B) shown in Figure 26 on page 25. If the LED is off, indicating that both fans are operating normally, continue to the next step. If not, remove the power supply assembly from the expansion unit and repeat the procedure starting with step 5 on page 21. If, after repeating the procedure, the power supply fan is not operating normally, contact your service provider.
