Depending on the severity of the short the HSBP may exhibit various levels of damage ranging from

discoloration to an exothermic event contained within the chassis.

Root Cause

There was an excursion with the laminate used in a specific lot code of the HSBP bare fabs. This excursion in

material makes the HSBP vulnerable to a low impedance short.

Corrective Action / Resolution

Exposure is limited to a maximum of 271 HSBP bare fabs manufactured between QSRU23310063 and

QSR30303019; see table below. Intel recommends replacement of suspect HSBPs upon request pending

suspect HSBP or BIK SN confirmation by Intel.

As there is limited traceability to the BIK level of HSBPs it is necessary to look at the HSBP serial number

located on the HSBP; see picture below.

As of September 30, 2013 all Intel inventory has been screened for the impacted Serial Number range and are

available for shipment.

The following IPMI commands may be used to access the FRU data:

To collect the data remotely:

 ipmitool -H <IP address> -U <user name> -P <password> fru

 ipmiutil fru -N <IP address> -U <user name> -P <password>

To collect the data on the local system:

 ipmitool fru

 ipmiutil fru
