Note to Support: A hardware tolerance issue has increased incidents of "false positives" of the VCORE_POK glitch on these systems. Firmware rev 8.1.5 or later stops these false positives. But if a Customer sees this VCORE on a system with sysfw 8.1.5 or higher, they could have a failed DCDC (D220) converter which requires troubleshooting and diagnostic procedures outside the scope of this Sun Alert.

Also Note: All other POK glitches different from false positive VCORE, such as DC_POK, IO_POK, etc. are not addressed by Firmware rev 8.1.5 or later. Normal troubleshooting procedures should be followed for those failures.
