34 Memory Replacement Instructions for the Network Processing Engine and Input/Output Controller
Removing and Replacing Memory DRAM SIMMs, SDRAM DIMMs, and Boot ROMs
Note The SDRAM DIMM sockets on the NPE-175, NPE-225, and NPE-300 are parallel
to the circuit board. They are not tilted at an angle.
Figure 24 Removing the DIMM
Handle the edges of the DIMM only; avoid touching the memory module or pins, and the
metal traces, or fingers, along the socket edge. (See Figure 25.)
Figure 25 Handling the DIMM
Caution
To prevent ESD damage, handle the DIMM by the card edges only. Place a removed
DIMM on an antistatic mat and store it in an antistatic container.
Step 6 Place the DIMM in an antistatic container to protect it from ESD damage.
This completes the DIMM removal procedure.
Installing New SDRAM DIMMs
The DIMM is a sensitive component that is susceptible to ESD damage. Handle the DIMM by the
edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the
connector edge of the DIMM). (See Figure 25.)
Caution To prevent ESD damage, handle the DIMM as shown in Figure 25.
