Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in
antistatic bags before placing them on any surface.
Caution – Do not remove any DIMM from its antistatic container until you are
ready to install it on the motherboard.
1. Power off the system, open and position the chassis.
Refer to:
■ “Powering Off the Workstation” on page 10-4
■ “Removing the Access Panel” on page 10-12
■ “Positioning the Chassis” on page 10-16
2. Locate the DIMM slots.
See FIGURE 11-1 and FIGURE 11-2.
Note – DIMMs are installed in consecutive pairs: DIMM0 and DIMM1 or DIMM2 and
DIMM3. Do not distribute a single pair of DIMMs across the two sets of slots.
Check placement of the DIMMs.
3. If you have not already done so, lift the DIMM cooling duct out of the way.
See Step 3 through Step 5 of “Removing DIMMs” on page 11-3.
4. Remove the new DIMM from its antistatic container.
Caution – Handle the DIMMs along the outside edges. Do not handle the DIMM
along the gold edge.
5. Align the DIMM with the slot.
Align the notch in the DIMM to the DIMM slot key. See FIGURE 11-8.
