Removing and Installing 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 Routing Engine board, or removing DRAM modules from the board.

The DRAM modules are located on the top of the Routing Engine, as shown in Figure 52.

Note: Use only DRAM modules purchased through Juniper Networks specifically for your model. Also, DRAM modules are not always transferable across J-series platforms. You can use the same DRAM module in both the J4350 and J6350 Services Routers. However, do not use a DRAM from another J-series platform in a J4350 or J6350 router.

To modify the DRAM configuration, use the following procedures:

• Removing a DRAM Module
• Installing a DRAM Module
