Backplane Guide Pins

Remove two screws from the System Board XDbus connectors before installing the system board in backplanes with guide pins. Guide pins were added to the backplane in December 1993 by ECO WO_05425 .

Notes

  1. The minimum operating system is Solaris 2.2.
  2. Solaris 2.2 supports 5 system boards.
  3. Solaris 2.2 supports 8 SuperSPARC modules on 4 system boards.
  4. Solaris 2.3 supports 20 SuperSPARC modules on 10 system boards.
  5. Install the highest level Boot PROM set in System Board 0.
  6. Use SPARC module and SBus board Standoff 330-1664-01.
  7. A root partition >2GB is not supported by Sun-4c, 4m, or 4d systems.

Memory Configuration Notes

  1. The minimum memory configuration is 8 SIMMs in Group 0.
  2. Install all Group 0 SIMMs on all system boards from the lowest board slot number to the highest. Then install SIMMs in Group 1 on all system boards. Refer to the Memory Module Installation Guide for installation performance guidelines.
  3. Use 8MB SIMM 501-1817 and 32MB SIMM 501-2196.

VT Vtt +1.2 Volts DC status OK Green
VC Vcc +5 Volts DC status OK Green

Notes

  1. The 40MHz Control Board is not compatible with the SC2000E System Board.
  2. The HOSTID and Ethernet Address are programmed into a 2KB × 8-bit Flash EEPROM in the TMS29F816 at U0203. The TMS29F816 is not field replaceable.
  3. The HOSTID and Ethernet Address are downloaded from the control board to the NVRAM on all system boards during POST.
  4. If the control board EEPROM content is invalid, the values stored in the NVRAM on System Board 0 are used.
  5. The Yellow LED on the keyswitch interface board is ON if the control board EEPROM content is invalid.
  6. Use the update-system-idprom OBP command to download the contents of the NVRAM on System Board 0 to a control board with an invalid EEPROM. OBP 2.11 is required.
  7. Use the following command sequence to invalidate the control board EEPROM:
    ok patch noop call update-system-idprom
    ok patch noop call update-system-idprom
    ok patch call noop update-system-idprom
    Power the system off and remove the Control Board.
  8. Use the following commands to change the NVRAM parameter that defines the location of the master system board:
    ok clear-master-nvram
    ok reset
  9. The 501-1671-04 has a 66MHz clock for the early production units with 33MHz SuperSPARC modules.
