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 Routing Engine contains one or two DRAM modules.

The DRAM modules are located on the top of the Routing Engine, as shown in Figure 61 and Figure 62.

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 transfer a DRAM module between a J4300 and a J6300 Services Router, but not between these models and any other Services Router.

To modify the DRAM configuration, use the following procedures:

• Removing a DRAM Module
• Installing a DRAM Module
