Compatibility Notes
- Sun Fire 280R is not compatible with 501-4143.
- Netra 20 was not tested with 501-4143.
- Netra 20 requires OBP 4.2 Version 4 and FIRE-I V1.2 (U2107).
- Netra 20 comes up as a Netra T4 with OBP 4.2 Version 4.
- OBP 4.2v4 and FIRE-I V1.2 are on 501-5938-07 and 501-6230-01.
OBP Notes
- The PROM contains Sun Blade 1000 and Sun Fire 280R OBP images.
- Sun Fire 280R and Netra 20 share the same OBP image.
- Sun Fire 280R requires a Remote System Control (RSC).
- Sun Fire 280R OBP is enabled when RSC is probed.
- Sun Blade 1000 OBP is enabled when RSC or Alarm are not probed.
- Netra 20 requires an Alarm Module and a System Configuration Card.
- Netra 20 uses the System Configuration Card MAC address and Hostid.
- Netra 20 Power Distribution Board includes an lm80 device.
- Netra 20 probes for SCCR, lm80, then Alarm during power-up.
UltraSPARC III Notes
- Mixing UltraSPARC III speeds in the Sun Blade 1000 is supported.
- Use torque tool 340-6091 or 340-6395 to install the UltraSPARC III.
Both are calibrated to 5.0 +/- 0.5 in/lbs (.565 Nm).
- The A28, A29, A35, and N28 systems include a torque tool.
UltraSPARC III Cu Notes
- Mixing UltraSPARC III Cu module speeds is not supported.
- Mixing UltraSPARC III and UltraSPARC III Cu modules is not supported.
- The 900MHz UltraSPARC III Cu requires OBP >=4.4 version 6.
- Changes to 501-6230-05 include FRUID SEEPROM 525-1897-02, OBP 4.5v10, and
removal of CR4201.
