Table 1: AM-7000 Memory Configuration
To install memory expansion SIMMs on the AM-176-10 board, use this procedure:
1. Memory SIMMs must be installed in pairs of equal capacity.
2. Always install the SIMMs of largest capacity first.
3. Always install the first pair of SIMM modules at Bank0. Use Bank1 for a second pair of SIMM
modules.
4. Insert the first SIMM in connector J4. Align pin-1 at the notched end of the SIMM module with
pin-1 on the connector, as shown in Figure 9.
5. Insert the SIMM module into the connector at a slight angle.
6. Rotate down toward the plane of the board.
The SIMM will engage the retainer clips and click into position, locking the SIMM in place at
about a 45 degree angle to the board.
7. Repeat steps 4 through 6 for the second SIMM, at connector J6. If you are using a second pair of
SIMMs, insert them into J5 and J7 using the same procedure.
After installing the SIMMs, the next time you power on the system, AMOS will automatically make the
memory available.
