NOTE: JPX3 in 12J6890 and 12J6830 is an
optional Jumper, the system board may come w/o it.
° System board FRU P/N 02K2551 comes with only 1MB video
memory and w/o cache memory.
° JP3 and JP5 is a 4-position Jumper block
Open = all jumpers removed
Closed = 4x jumper present (1-2, 3-4, 5-6, 7-8)
Processor Type Jumper Settings II
You must check out exact processor type before setting the processor type jumper.
The wrong processor type jumper setting may damage CPU, especially the single/dual voltage setting.
