Removal
1. Remove the appropriate memory module from the card cage.
2. Place the module on an ESD pad on a level surface. Remove both module
covers by removing the eight screws from each. (The screws that attach to
the end plate of the module are larger than those that attach to the
standoffs.)
3. Use an adjustable wrench to remove the standoff at the end of the row with
the failing SIMM. See
4. Beginning with J2, J12, or J24 on the E2035 module or with J2, J14, or J28
on the E2036 module, remove each SIMM up to and including the failing
SIMM. To remove a SIMM, release the latch on each end of the connector
by inserting a Phillips screwdriver into the slot and pressing down. See
Figure 5-2. (See Figures 5-3 and 5-4 for SIMM connector numbers.)
Replacement
1. Insert the replacement SIMM into the connector at a 45-degree angle. As
you rotate it to an upright position, the latches will snap into place. (The
SIMM is keyed on the sides and in the center so that the correct side faces
front.)
2. Insert the other SIMMs in their connectors.
3. Replace the standoff. The square standoff goes on side 1 (the component
side) and the hexagonal standoff on side 2. Torque the standoffs to 12 inch-
pounds (15 inch-pounds maximum).
4. Replace the module covers and replace the memory module.
