This section provides the most common repair procedures for the 
  Ultra 80 workstation. The written procedures below are links to the

    | 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).440MHz and 450MHz UltraSPARC II Modules in Ultra 60/80, Enterprise 
          220R/420R and Netra t platforms may experience Red State Exception, 
          Send Mondo Timeout and hard hangs (FCO A0208-3). | 
   
    |  Disk Drive | 
        
           Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue (I1136-1 ). 
          18.2GB and 36GB IBM disk drives may be susceptible 
            to early life failures problem (FIN I0724-2 ).Systems with 18.2GB and 36GB IBM disk drives may experience higher than expected failure rate.
           (FCO A0182-2).

    | 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). | 
   
    | 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). | 
   
    | UPA Graphics Card | 
         
           
            The 'fbconfig' (1M) command may return incorrect 
              part number for XVR-1000 Graphics Accelerator (FIN I0945-1 ).
          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 ). |
