It is possible POST may assign a new system master in a different slot if the original system master fails. If this occurs, correct it and install a fully functional system board in slot 0. 10-2 SPARCcenter 2000/2000E Service Manual—June 1996...
Page 207: Replacement Parts
If a serial-interface console is used, it must be plugged into RS232 connector A on the system master. If a color monitor is used, a color-graphics interface card must be installed in SBus slot 1 on the system master. Also, by convention, install system boards in the lowest card cage slot numbers first.
Page 208: Figure 10-2 Replacement Part Locations
The remaining components may be referred to in system error messages (by part number) but they cannot be replaced in the field. Failure of any of these components requires replacement of the system board. 10-4 SPARCcenter 2000/2000E Service Manual—June 1996...
Page 209: System Boards And Component Replacement
System Boards and Component Replacement This chapter provides information about removing or replacing: • System boards • SuperSPARC modules • SBus cards • SIMMs and NVSIMMs • OpenBoot PROMs 10.1 System Board To remove and replace a system board, see Section 7.4, “Rear Screen Panel,” for access to the card cage.
Page 210 Note – The board with the highest revision-level Boot PROMs must be installed in the system master position, slot 0. To determine which board to install in slot 0, see Appendix E, “General Rules for System Configuration.” 10-2 SPARCcenter 2000/2000E Service Manual—June 1996...
Page 211: Using Standoffs
Note – Your board may already have the current dash-revision Boot PROMs installed. If so, do not replace them. Compare the dash-revision of Boot PROMs installed on your board against those provided in this kit. Replace the Boot PROMs ONLY if they are of a lower dash-revision level than those in this kit. 2.
Page 212: Supersparc Modules
The system board can have zero, one, or two SuperSPARC modules. See Figure 10-3. If you are adding a new SuperSPARC module, see Section E.3.1, “SuperSPARC Modules.” Caution – Use the Sun ESD kit P/N 250-1088 for these procedures. 10-4 SPARCcenter 2000/2000E Service Manual—June 1996...

Page 214: Sbus Cards
Save the screws for installation of a replacement SBus card or a filler panel. 2. Unlock the SBus card by pulling up the tips of the two standoffs. Pull up the tip of a standoff to unlock it. See Figure 10-2. 10-6 SPARCcenter 2000/2000E Service Manual—June 1996...
Page 215 3. Hold the card by the edges near the connector and gently rock the card back and forth to loosen it from the socket. Caution – The connector housing will break if the SBus card is tilted too far. 4. Lift the SBus card from the socket at an angle while guiding the face plate out from the backpanel opening and under the springfingers.
Page 216 4. For DSBE/S card only: remove the two outer retaining screws, but do NOT remove the middle screw or the springfinger. You will need a #1 Phillips screwdriver and a 3/16 nut driver or socket wrench. See Figure 10-8. 10-8 SPARCcenter 2000/2000E Service Manual—June 1996...
