Removing and Installing Line Card Memory
Figure 19 Retaining Clip Completely Installed into Module Latch
Note The retaining clip is not used with all ISE, Engine 4, and Engine 4+ line cards. If your SODIMM socket
does not include the retaining clip; there is no problem. Simply ignore any instructions that refer to the
clip.
Checking the Installation of Route Memory
After you install line card memory and reinstall the line card in the router, the router reinitializes the line
card and detects the memory change as part of the reinitialization cycle. The time required for the router
to initialize can vary with different router configurations and memory configurations.
If the line card does not reinitialize properly after you replace the SODIMM, or if the console terminal
displays a checksum or memory error, verify that you installed the correct SODIMM and that it is
installed correctly on the line card.
To check the installation of line card memory, follow these steps:
Step 1 Remove the line card from the router.
Step 2 Check the alignment of the SODIMM, looking at it across the horizontal plane of the card. The
SODIMM should be aligned at the same angle as shown in Figure 17 and be fully inserted into its socket.
If a SODIMM is not correctly aligned, remove it and reinsert it.
