4.8 Replacing a SIMM
SIMMs are removed from their slots at oblique angles, as shown in Figure 4–6.
Therefore, any SIMMs installed above a failed SIMM must be removed first:
• On the system board, remove SIMMs in order from slots J0651, J0650,
J0551, and J0550 (see Figure 4–7 and Table 4–8).
• On the memory expansion module, remove SIMMs in order from slots J1 or
J5, J2 or J6, J3 or J7, and J4 or J8. (see Figure 4–8 and Table 4–9).
The following steps describe the removal procedure for a SIMM.
1. Shut down the system and unplug the power cord (Section 4.4).
2. Remove the cabinet top cover, left side panel, and card cage cover using the
procedure in Section 4.5.
3. If the failed SIMM is on the memory expansion module, remove the
memory module using the procedure in Section 4.9.
4. If the failed SIMM is on the system board:
a. Remove the CPU module using the procedure in Section 4.6.
b. If a memory expansion module is installed, remove it using the
procedure in Section 4.9.
5. Clips on each end of the memory slot hold the SIMM in place. Use your
finger or a small flat-blade screwdriver to press these clips outward.
6. Tip the SIMM toward the top edge of the board or module and pull the
SIMM out of its slot.
Reverse the above procedure to install the SIMM.
