The following table provides tips associated with each component.

Component Tips
CPU/Memory Board
  • Marginal seating of Sun Fire V490 and V480 CPU/Memory boards is causing hard to diagnose non-fatal, fatal, and CPU/Memory board power-on faults (FAB 1000557.1).
Memory
  • On certain Sun Systems a small number of 512MB and 1GB Micron DIMMs may experience premature failures with Uncorrectable Memory Error (UE) messages. (FAB 1000920.1) (formerly FCO A0285-1)
  • Applications using large memory page sizes on UltraSPARC IV+ CPUs may hang or core dump (FAB 1001194.1).
Disk Drive
  • Improved firmware for Seagate 10K.6 disk d rives will reduce the incidence of unexpected outages due to a spindle motor issue (FIN I1136-1).
  • Seagate Cheetah 7 146GB FC-AL and 73 GB FC-AL disk drives may experience higher than expected failure rates due to spindle motor failure (FCO A0256-1).
IDPROM Module
  • USB failures seen on V480/V490 systems with OBP 4.17.1 and 4.18.2. (FAB 1000377.1).
Graphics Card
  • XVR-600 graphics card can cause rendering performance issue when performing simultaneous rendering update with OpenGL windows. (FIN I1161-1).
CPU Modules
  • Panther 1500MHz CPU/Memory boards (501-7058-xx) are being replaced unnecessarily. (FAB 1000220.1).
  • OBP update required for Panther based Sun Fire V490 and V890 systems to enhance Processor Illegal Command Detection. (FAB 1017414.1).
