Replacing DRAM Modules

The DRAM installed on the Routing Engine provides storage for the routing and forwarding tables and for other Routing Engine processes. The design of the Routing Engine allows you to modify the DRAM configuration by adding DRAM modules to the system board, or removing DRAM modules from the board.

The DRAM modules are located on the top of the system board, as shown in Figure 86 and Figure 87. Two pairs of slots are available for installing DRAM modules. Installing DRAM modules in slots away from each other provides better performance than installing them in two adjacent slots.

Note: Use only DRAM modules purchased through Juniper Networks specifically for your model.

To modify the DRAM configuration, use the following procedures:

• Removing a DRAM Module
• Installing a DRAM Module
