About replacing the memory card assembly

The memory card assembly contains the SDRAM DIMMs of your system and is connected to the motherboard. Replacing the memory card assembly consists of the following procedures:

Removing the memory card assembly

Installing the memory card assembly

To install the memory card assembly, complete the following steps.

Step	Action
1	Hold the memory card assembly by the sides to avoid damaging the components.
2	Carefully insert the memory card assembly straight into its riser slot. The memory card assembly fits tightly in the slot, but should go in easily. If not, realign the memory card assembly with its riser slot and try again. Caution Visually inspect the memory card assembly to verify that it is evenly aligned and fully inserted into the slot; otherwise, the edge connector on the memory card assembly does not make complete contact with the slot.
3	Push carefully, but firmly on the top edge of the memory card assembly until the latches snap into place.
4	Lower the PCB carrier crossbar and secure it on top of the memory card assembly by tightening the thumbscrew.
5	Go to Closing the PCB carrier.
6	After turning on the storage engine, run diagnostics on your new memory card assembly. See the Diagnostics Guide for more information.
