Preparing the Processors

Installing the MPX Processor

The Altos 15000 supports up to four 486/50 modules. These modules are attached to the main processor card (see Figure 2-18) which plugs into S-bus slots on the motherboard (see Figure 2-19). The Altos 15000 is shipped with one processor present. The second CPU module must be installed at the customer site.

The Altos 15000 has four S-bus slots next to the ten general purpose slots. These S-bus slots are the four unnumbered slots at the front of the Altos 15000 system unit. These slots hold the CPU board and memory boards and each slot is limited to a particular type of board. S-bus Slot 1 is the front-most slot and contains the CPU board holding both CPUs. S-bus Slot 4 is the fourth slot in from the front and contains the memory board (see Figure 2-19).

Prior to installing the MPX, you must have the following parts:

•Intel486t DX CPU-CACHE Module

•Five hexagonal separator posts approximately 7/16I long

•Three hexagonal nuts 1/8I in diameter

•Five Phillips-head screws approximately 3/16I long
