DIMM/SIMM Memory Cards This procedure describes how to remove and replace the DIMM (cache) memory card and SIMM memory card contained in the controller modules. This procedure is required when replacing failed DIMM/SIMM, or transferring the DIMM to a replacement controller module. Note Replacement controllers contain SIMM but do not include DIMM. When a new controller module is being installed, the DIMM must be removed from the existing controller module and transferred to the new, replacement, module. Replacing DIMM/SIMM Memory Cards 1. Remove the controller module from the controller enclosure. See "Controller Module" on page 332. CAUTION Electrostatic charges can damage sensitive components. Use a grounding wrist strap or other antistatic precautions before removing or handling the components. 2. Attach an antistatic wrist strap to your wrist and ground the other end to the controller module case. Place the controller module on an antistatic mat. 3. Remove the controller module cover (see Figure 118, below) by removing the six screws from the top of the cover. Lift the cover off of the controller module body. If transferring the DIMM to a replacement controller module, remove the module cover from both the previously installed controller module and the new controller module. 4. Remove the DIMM or SIMM card, you are replacing, from the controller module: - Remove the DIMM by prying outward on the ejector levers and lift the card from the connector. - Remove the SIMM by pressing outward on the metal connector clips then swing the top of the card forward and pull it upward to free it from the connector. 346 Internal Controller Enclosure Assemblies
