Hi Admins,
 
I've got an old E10K with some system board and fan oddities.
 
The box has got 5 system boards (20CPUs). 0 1 2 3 seem fine but 4 and
5
show no lights on the sw-0 - sw-7 array. I'm not sure what these 8
LEDs
signify. Earlier today, I powered the entire box down and on restart,
all sets of lights came on. Shortly after, the lamps on boards 4 and 5
were out again. After another restart, the lamps on boards 3 4 and 5
were out. Does anybody have any ideas? In fact, does anybody know what
the lamps represent?
 
In addition, fan trays 8-15 show fail but they're all on. Again, I've
no idea.
 
Any advice gratefully received.
 
Thanks,
 
Isaac
