4. Unlock two more SIMMs to make space for the faulty SIMM to tilt
forward far enough to be free of the locking pins.

5. Remove the SIMM from the socket and place it in an antistatic bag.
10.5.2 Replacement
Caution – Do not mix 8 Mbyte SIMMs with 32 Mbyte SIMMs (or 1 Mbyte
NVSIMMs) in the same group. (However, SIMMs of different manufacturers are
interchangeable in a group if the SIMMs have identical capacity and speed.)
1. Orient the system board so the backplane connector faces you.
2. Remove the SIMM (or NVSIMM) from the antistatic package.
3. Hold the SIMM at the edges, with pin 1 to the left.
The side alignment notch (Type A) or double notch (Type B SIMM or Type C
NVSIMM) are at the left side.
4. Guide the SIMM into the slot at an angle so the SIMM connector pads
touch the bottom of the socket.
The SIMM bottom alignment notch must align with the tab in the socket
center. Ensure the locking pins align with the holes in the sides of the SIMM.
5. Tilt the SIMM upright to lock it in place.
The locking tabs should automatically lock around the SIMM.
Note – The SIMM should require very little insertion force. If the SIMM doesn’t
seat properly, or if a replacement SIMM is made by a different manufacturer,
the replacement SIMM may be backward; verify the SIMM alignment holes
and notch exactly match the corresponding parts of the socket.
