You can order your 1510 CPU with many DRAM configurations. To reconfigure the
DRAM capacity, change the DRAM SIMMs on your board. For more information, refer
to the CPU manual.
ISA or PCI Boards
Warning
Total power available for ISA and/or PCI boards is 85 W maximum.
Total power for +5 V DC and +3.3 V DC combined (summed) must not
exceed 45 W.
The following instructions describe the installation of PCI or ISA expansion boards.
1.
Turn off power to the unit and unplug the power cord on the rear of the 1510.
2.
Check that the board’s memory and I/O configuration do not conflict with the CPU
and I/O memory maps in your CPU board manual.
3.
Remove the side panel. With the front of the unit facing you, lay the 1510 on its right
side. Remove the eight screws that hold the left side panel in place (see figure 1-1).
4.
Remove the ORB screw and blank ORB from the desired track (see figure 3-5).
5.
Remove the two (2) screws from the hold down bracket and remove the hold down
bracket (see figure 3-5).
6.
Slide the ISA or PCI expansion board into the desired slot.
7.
Push the board into the backplane connectors.
8.
Use the clamps included in the kit shipped with your unit to secure the board to the
hold down bracket (see figure 3-5).
Note
Do not
force the boards or apply uneven pressure.

Secure the board by installing the screw through the hole in the board’s metal ORB
and into the top of the track.
