Exchanging a DRAM Feature
| Removal and replacement procedures for the PMC adapter depend on the type of
| system card installed in the IBM 2212. You can not install or use the DRAM SIMM
| memory from the standard system card on the high-performance system card. If
| you have a high-performance card you must use DRAM DIMM memory.
|
Exchanging a DRAM Feature on a Standard System Card
| Refer to “Handling Static-Sensitive Devices” on page 2-2 before exchanging a
| DRAM feature.

| 1. Remove power from the IBM 2212 by unplugging the power cord.
| 2. Remove the cables from the standard system card. You may want to label
| each cable as you disconnect it for ease of reconnection.
| 3. The standard system card is secured with two levers. To remove this adapter,
| release both levers by pushing outward on them.
| Remove the card from the IBM 2212.
| 4. To remove the DRAM SIMM, use your thumbnail or a small non-metallic device
| to gently pull the spring latch away from each end of the DRAM SIMM. Gently
| tilt the DRAM SIMM away from the center of the system card and remove the
| DRAM SIMM from its connector socket.
| 5. Remove the new DRAM SIMM from its packaging. Handle it by the ends
| without touching the components or gold connection tabs.
| 6. Insert the DRAM SIMM into its slot by placing it, connector-edge down, into its
| socket. Applying slight pressure to the top edge, push the DRAM SIMM toward
| the center of the system card until it snaps into place.
| 7. Slide the new card along the grooves in the slot and secure the two levers. To
| lock the card into place, pull each lever inward.
| 8. Reattach the cables to the standard system card.
