This section provides the most common repair procedures for the
Netra 20, which are included in the following manual:
| Component |
Tips |
| CPU Module |
- Guidelines for understanding and diagnosing UltraSPARC III Level 2
(L2) SRAM Cache Memory Errors (FIN I0887-1).
|
|
Disk Drive (Hot Swap)
|
-
Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue ( I1136-1).
- Seagate ST336605FC 36GB and ST373405FC 73G drives could be susceptible
to label corruption (FIN I0816-1).
- Recovering from a failed FCAL boot disk (Problem article 1008580.1).

| Disk Drive (Unmirrored Root Disk) |
-
Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue ( I1136-1).
- Seagate ST336605FC 36GB and ST373405FC 73G drives could be susceptible
to label corruption (FIN I0816-1).
- Recovering from a failed FCAL boot disk (Problem article 1008580.1).
- 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).

| Graphics Card |
- XVR-500 Graphics Accelerator card does not function properly in Netra
20 servers (FIN I0900-1).
|
| Memory |
- Best Practices Guide for Memory Errors for diagnosing UltraSPARC III
memory errors now available (FIN I1018-1).
- Diagnosing Main Memory errors versus L2SRAM errors on UltraSPARC III
and UltraSPARC III Cu systems (FIN I0954-1).
- A sub-population of DIMMs that shipped between 2001 and 2002
on the below platforms are showing significantly lower
reliability than expected (FCO A0253-1).
- Systems containing 256MB Samsung B-die DIMMs, having a module date
code between 0115 and 0127 (built between weeks 15 and 27 of 2001),
may experience Uncorrectable Memory Errors (UE). This can lead to System
Panics (FCO A0223-1).
|
| PCI Card |
- UltraSPARC III systems may panic due to a conflict between the Schizo
2.4 ASIC and the GigaSwift Ethernet PCI Card (FIN I0874-1).
|
| System Board |
- UltraSPARC III and III+ based platforms could be susceptible to UCC
errors that may cause system panics (FIN I0856-1).
