Removing and Installing Line Card Memory
Remove the new DIMM from its protective antistatic bag.
Step 3
Grasp the edges of the DIMM only. (See

DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.
To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches

(keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in
the socket.
If necessary, rock the DIMM back and forth gently to align it in the socket.
When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM

socket, you must return the line card for repair.
Gently insert the DIMM into the socket and push until the DIMM snaps into place and the release lever

is flush against the side of the socket. (See
Verify that the release lever is flush against the side of the socket. If it is not, the DIMM might not be

seated properly. On a socket with dual release levers, both levers should be flush against the sides of the
DIMM.
If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush
against the side of the DIMM socket.

Step 8
Removing a SODIMM
ISE, Engine 4, and Engine 4+ line cards use a different type of route memory than Engine 0, 1, and 2
line cards. A 144-pin small outline DIMM (SODIMM) is used for route memory. To remove a SODIMM
from a line card, follow these steps:
Step 1
Attach an ESD-preventive wrist strap and follow its instructions for use.
Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 2
Locate the route memory socket on the line card. (See
Step 3
4 and Engine 4+ line cards.)
Remove the SODIMM memory-retaining clip from the memory module socket. Grasp the latch arm

intersection located on each side of the clip and gently slide the clip out. (See
retaining clip.
If the retaining clip is bent or damaged, do not attempt to fix or reuse it. This can cause serious damage

to the line card. Each SODIMM replacement ships with a spare retaining clip, in case there is any
damage to the existing clip.
