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

.

c. Press the module fully into the slot to engage the lock levers.

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.
