Severity

Description

Fault due to XSCF software-detected problems on the command interface between the XSCF and a MBC chip.

Automated Response

For M12-1 and M12-2 systems, no immediate action is taken.

For M12-2S systems, for faults that can be isolated to a specific MBC chip, the XSCF switches the command interface to another Building Block in the PPAR with a functioning command interface. If there is no alternate Building Block to use, then no immediate action is taken for this case.

For faults that cannot be isolated to a specific MBC chip, the XSCF is rebooted.

On a M12-2S system, the standby XSCF will take over as the active XSCF.

Impact

For M12-1 and M12-2 systems, if the fault is isolated to a specific MBC chip, the platform becomes unbootable.

For M12-2S systems, if the fault is isolated to a specific MBC chip, the building block becomes unbootable.

If the fault cannot be isolated to a specific MBC chip, nothing is deconfigured.

Indicted Hardware

For faults that can be isolated to a specific MBC chip:

For M12-1 and M12-2/M12-2S systems, the MBU (M12-1), CMUL or XSCFU (M12-2/M12-2S) is marked for replacement.

For faults that cannot be isolated to a specific MBC chip, the problem may be in the XSCF software or it may be some undiagnosable hardware problem.

Suggested Action for System Administrator

The recommended service action for this event is to schedule replacement of the affected component(s) at the earliest possible convenience. Although the hardware may be functioning, it is not intended nor recommended that the faulted component(s) remain in the system for a prolonged period of time.

Refer to the following document for the latest procedures for displaying event content in preparation for submitting a service request and applying any post-repair actions that may be required.
