4365.0. "LEDs on VAXstation 4000-9x?" by DRAGNS::SAUNDERS (John Saunders, DECdns Engineering, (508) 275-5424) Wed Apr 30 1997 12:08

I'm attempting to resurrect a VAXstation 4000-96 which had been stripped of
memory and disks (so I've probably installed something wrong).

I'm getting an "F2" (hex) on the LEDS almost immediately, and no self-test
output.

Does anyone know what this means?

Is there a list of these codes somewhere? We've got several of these boxes,
and I'm sure we'll want to know in the future. Is there any hardware doc for
these online?

Thanks,
John Saunders

4365.1check 4 memory simmsHARMNY::CULLISONWed Apr 30 1997 15:4010
    I do not have these codes but check the memory SIMMs carefully. You
    will need FOUR SIMMs and they must be installed in the correct slots.
    
    The VAX station firmware cannot powerup without some good memory
    present, the disk will not matter. Without good memory there are no
    error printouts other than LEDs that I know of.
    
    MV3100-85 and above or VAX 4000-nn do not require any memory to get
    normal error printouts.

    If the 4 simms are next to each other, you have them in wrong. You need
    to look down on the right hand side of the simm sockets to see which
    row is for bank 0 or 1.
