Chapter 5 Installing Memory in the Router
Replacing DRAM and SDRAM
DRAM SIMM Orientation
SIMMs have a polarization notch to ensure proper orientation and alignment holes to ensure proper
positioning. Figure 5-7 shows the polarization notch and alignment holes on a SIMM. DRAM SIMMs
are installed with the connector edge down and the polarization notch near the front 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 SIMMs.
