Replacing Cisco 3725 SDRAM

SDRAM DIMM Location and Orientation

Figure 2 shows the location of dynamic memory—SDRAM DIMM sockets 0 and 1—in a Cisco 3725

router.

DIMMs are manufactured with polarization notches to ensure proper orientation, and alignment holes to

ensure proper positioning. Figure 3 shows the polarization notches and alignment holes on a DIMM.

SDRAM DIMMs are installed with the connector edge down and the polarization notches toward the left

side of the chassis.

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 DIMMs.
