Tips
Audio Module Assembly  
CD-ROM Drive  
CPU Module
  • Tuning the ecache_scan_rate parameter of the Solaris cache scrubber provides improved Ecache parity error protection on non-mirrored SRAM UltraSPARC II-based systems (FIN I0755-1).
  • OS mapping versus physical location of CPU modules for E420R, E450, U80 and Netra t1400/t1405 systems may lead to incorrect module replacement (FIN I0749-1).
  • The current diagnostic procedure to identify the faulty CPU module from CPU Ecache parity errors is flawed (FIN I0570-3).
Disk Drive
  • 18.2GB and 36GB IBM disk drives may be susceptible to early life failures problem (FIN I0724-2).
  • 18GB and 36GB IBM disk drives experiencing high failure rate in high humidity and high temperature environments (FCO A0182-1).
Floppy Drive  
Memory  
Memory Riser Assembly
  • See Memory Riser Assembly Damage Caution.
  • System initialization failures are sometimes being diagnosed incorrectly due to an improperly installed Memory Riser card (FIN I0607-1).
  • Failure to properly assemble the Memory Riser to the correct torque setting can cause intermittent memory related system problems (FIN I0537-2).
NVRAM/TOD Module  
PCI Card
  • Ultra 80 system board based systems may panic at boot time with certain PCI Bus configurations (FIN I0665-1).
  • SunPCi II and SunPCi IIpro cards may not respond after rapid/successive power cycling (FCO A0186-1).
  • A host system using the 375-0040-01 or -02 FC100/P FC-AL PCI card to attach to FC-AL storage (StorEdge A5x00 and A3500) may experience loop errors, which may affect data access to that storage (FCO A0164-1).
  • Systems based on the PSYCHO chipset panic with a PCI bus error (SRDB 40602).
Peripheral Assembly (contains CD-ROM, Tape Drive, and Floppy Drive)  
Power Supply Assembly  
System Board

Tape Drive  
UPA Graphics Card
  • SunBlade 1000/2000 and Ultra 60/80 systems may exhibit a blank screen upon boot up with an XVR-1000 Graphics Accelerator installed (FCO A0200-1).
