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.
