Type

Hardware Fault

   power.power-off

Severity

Major

Description

A fault occurred when the XSCF tried to turn off the power of the DDC (DC-to-DC Convertor) on:

- MBU or PSUBP for M10-1;
- CMUL or PSUBP for M10-4
- CMUL, PSUBP or XBU for M10-4S
- XBUX for XB-Box

or

A fault occurred when the XSCF tried to power-off the PSU.

Note that, under certain conditions, it is possible to generate this fault when a power-off is attempted and an external USB-powered device is connected to either the front or rear USB port e.g. a USB DVD drive. If this is the case, remove the external USB device, clear the fault and retry the power-off operation. See document 1904125.1

The recommended DVD drive and AC adapter is Oracle option 7106761 External USB DVD drive with AC adapter.

Automated Response

No immediate action is taken because of this fault, and the poweroff sequence continues. The platform administrator should schedule a service action.

Impact

When the failure is detected on a PSU, the PSU is deconfigured. If enough PSUs are now non-operational:

- the platform becomes unbootable for M10-1 or M10-4 systems.
- the Building Block becomes unbootable for M10-4S systems.
- the XB-box becomes unbootable, and Building Blocks using this XB-Box will start with one deconfigured XB way at next power-on.

For other failures, the following part will be deconfigured:

For M10-1 systems:

- when failure is detected on MBU, MBU is deconfigured
- when failure is detected on PSUBP, PSUBP is deconfigured.

This means the platform is unbootable.

For M10-4 systems:

- when failure is detected on CMUL, CMUL is deconfigured
- when failure is detected on PSUBP, PSUBP is deconfigured.

This means the platform is unbootable.

For M10-4S systems:

- when failure is detected on CMUL, CMUL is deconfigured, and the Building Block becomes unbootable.
- when failure is detected on PSUBP, PSUBP is deconfigured, and the Building Block becomes unbootable.
- when failure is detected on XBU, XBU is deconfigured, and the Ppar using this Building Block will start with one XB way deconfigured.

Indicted Hardware

Depending on where the failure is detected, the suspect is as listed below:

- MBU for M10-1: MBU is marked for replacement.
- PSUBP for M10-1: PSUBP is marked for replacement.
- CMUL for M10-4: CMUL is marked for replacement.
- PSUBP for M10-4: PSUBP is marked for replacement. There is also small chance that the problem is actually in CMUL.
- CMUL for M10-4S: CMUL is marked for replacement.
- PSUBP for M10-4S: PSUBP is marked for replacement. There is also small chance that the problem is actually in CMUL.
- XBU for M10-4S: XBU is marked for replacement. There is also small chance that the problem is actually in CMUL.
- XBUX for XB-Box: XBUX is marked for replacement. There is also small chance that the problem is actually in XSCFUX.
- PSU: The PSU is marked for replacement. There is a slight chance the MBU (for M10-1 systems), CMUL (for M10-4/4S systems) or XSCFUX

  (for XB-Box) is at fault.

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.
