MAP4100 Repairing a service processor (FSP) problem

• Yes, repair the problem using the serviceable event. Return to this MAP if you still have a service processor problem following the repair.
• No, continue with the next step.

• Yes, go to System reference codes overview.
• No, continue with the next step.

Note: The DC good LED might be on or flashing. This does not affect service processor power. See Figure 1.

Is the input power good LED lit solid on at least one of the power supplies for the CEC enclosure?

• Yes, continue with the next step. This will take you through a power cycle of the CEC to reset the service processor.
• No, this problem should not normally occur on a single CEC enclosure. Do the following:
  • Check that all power distribution cables are plugged.
  • Check that the rack operator panel UEPO switch assembly is enabled.
  • Check that customer AC input is available - look for 'AC Input Good' LED on the rear of the primary power supplies.
  • If no problem is found, then contact your next level of support.
