Replacing Cisco 3745 SDRAM

SDRAM SODIMM Location and Orientation

The Cisco 3745 router mainboard includes one SODIMM socket, that supports two SDRAM SODIMMs one on top of the other. You must remove the top SODIMM to gain access to the one on the bottom.

Figure 9 shows the location of dynamic memory—that is, SDRAM SODIMMs—in the Cisco 3745 router.

Caution To avoid damaging ESD-sensitive components, observe all ESD precautions. To avoid damaging the underlying mainboard, do not use excessive force when you remove or replace SODIMMs.
