Memory Configuration Guidelines
Follow these guidelines when you replace or add memory to the computers:
• Use only standard unbuffered memory modules that conform to
non-ECC 240-pin DDR3 SDRAM (PC3-10600) standards.
• Use only DDR3 type memory modules.
• Use only memory modules with gold-plated contacts.
• Always handle a memory module by its edges.
Replace or Add a Memory Module
Follow these steps to replace or add a memory module.
1. Follow the steps for Pre-configuration on page 36 .
2. Remove the computer cover as detailed in Remove the Cover on
page 38 .
3. Locate the memory module that you want to replace.
See System Boards on page 17 for memory location on the
motherboards.
4. Remove the selected memory module.
a. Use your thumbs or two fingers to push open the lock levers, which
release the memory module from its slot for easy removal.
See
Figure 11 on page 42 .
b. Gently pull out the memory module to remove it from its slot.
c. Place the memory module on a static-dissipating work surface or
inside an antistatic bag.
5. Install the new memory module.
a. Hold the memory module by its edges as you remove it from its
antistatic bag.
b. Orient the module so the notch on its bottom edge aligns with the
keyed surface of the DIMM slot.
See
Figure 11 on page 42 .
IMPORTANT We recommend that you use only Allen-Bradley approved memory
modules. See
http://ab.rockwellautomation.com/Computers for
qualified replacement parts and accessories.
IMPORTANT Use an antistatic wriststrap that is connected to the work surface, and
properly grounded tools and equipment.
TIP To install more memory, go ahead to step 5 of this section.
IMPORTANT When you install memory in pairs, install modules in slots 1 and 3 or
slots 2 and 4 for optimal performance.
TIP The keyed surface is off center to assist the correct alignment.
