- We are running a SUN3/160 system. We would like to
- expand memory from 8 to 16 MB.
-
- current (running) configuration:
-
- Backplane: ( 501 105 301 048 )
- slot 1: 3/160 CPU with 4 MB ( 501 116 403 788 )
- slot 2: 1st 4 MB Sun Mem Exp ( 501 113 211 495 )
- slot 9: SMD Controller ( 501 116 604 733 )
- slot 11: Sun VME SCSI Controller ( 501 123 608 008 )
-
- Following SUN document `cardcage slot assignments and backplane
- configuration procedures' first memory expansion should be
- placed in slot 5. When trying this CPU will recognize only 4 MB.
-
- 2nd and 3rd memory expansions are never found.
-
- To ensure that memory is working we tested each board as
- 1st expansion in slot 2.
-
- Each memory is configured following SUN document `Memory Board
- Configuration Procedure'
-
- EEPROM parameters were changed according to new configuration.
-
- Does anybody have any advice or hints ?
-
- Can anybody help us to get answers to following questions
-
- - how is the SUN memory bus organized, is there a slot dependend
- addressing of boards ? (If not we probably have a broken backplane)
-
- - our PROM Monitor ( compiled 5/22/89 ) has only extended selftest
- for keyboard, ethernet and seriell ports. It seems strange that
- there is no memory test.
-
- - should there be any termination of the memory bus ? How could this be
- achieved ?
-
- - does anybody have something like a SUN part number listing to verify that
- we have parts which will work together ?
-
- - Does anybody know where to get further hardware documentation
- ( CPU board, FPA installation, etc. .. )
-
- - I noticed three empty sockets on the CPU board near the memory
- and the P3 connector. They are labeled with P2/110, 9518, AL5254.
- Does anybody know about their purpose ?
-
- thank`s for any help
