Procedure

Use Service Management > Manage Serviceable Events to view the list of open serviceable events.
Do you have a serviceable event that is indicating a failure with the service processor(all models) or CEC enclosure system backplane (model 961)?

- No, go to step 5.
Have both management consoles lost connectivity with this single system (CEC enclosure)?
- Yes, go to MAP4100 Repairing a service processor (FSP) problem.
