Removing a DIMM

To remove a DIMM from a line card, follow these steps:

Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the DIMM sockets on the line card.

Note Some line cards use DIMM sockets equipped with dual release levers, as shown in Figure 48; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 49. Both DIMM sockets operate in the same general way.
