General Memory Information

Be sure to unplug the power cable before removing or installing the memory modules to avoid damage to them.

The memory modules do not need to be installed in pairs and can be installed in any slot on the system board. There is no requirement that one slot be installed before the other.

Refer to “Memory Modules” on page 7-26for locations of the memory modules and instructions on removing and installing modules.

Note: If the symptom changes while using this MAP, check for loose cards, cables, and obvious problems. If you do not find a problem, go to “MAP 1540: Minimum Configuration” on page 2-17.
