Removing a SDRAM SODIMM

This section provides a procedure for removing the small outline dual in-line memory module (SODIMM)

on the NPE-400.

Follow these steps to remove the existing SODIMM:

Step 1 Remove the NPE-400 from the system.

Step 2 Place the NPE-400 on an antistatic mat or pad and ensure that you are wearing an antistatic device, such

as a wrist strap.

Step 3 Locate the SODIMM (see Figure 9-13).
