Upgrading the SDRAM Memory Modules
Caution
Handle the edges of the DIMM only; avoid touching the memory module, pins, or traces (the metal
fingers along the connector edge of the DIMM).
Figure 6-10 Handling the DIMM
Caution
To prevent ESD damage when working with DIMMs: handle the DIMM by the card edges only, place a
removed DIMM on an antistatic mat, and store it in an antistatic container.
Step 5
Place the DIMM in an antistatic container to protect it from ESD damage.
Replacing the SDRAM DIMM
Note
The network processor card contains two SDRAM slots for user-configurable system memory, DIMM
1 and DIMM 2.
•
The amount of memory installed in slot DIMM 1 must be greater than or equal to the memory
installed in slot DIMM 2.
•
Slot DIMM 2 is zero for the default memory configuration of 128 MB.
•
Slot DIMM 0 is used only for packet memory and is fixed at 64 MB in the factory.
To replace the SRAM DIMM, do the following:
Step 1
Make sure that you are properly grounded.
Step 2
Remove the new DIMM from its antistatic container.
