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 dual inline memory modules (DIMMs) to the Routing Engine board, or removing DIMMs from the board. The Routing Engine contains one or two 168-pin DIMMs.

The DRAM modules are located on the top of the Routing Engine, as shown in Figure 36 and Figure 37.

DRAM modules are not transferable across J-series platforms. Do not install a J2300 DIMM in a J4300 chassis, for example.

To modify the DRAM configuration, use the following procedures:

• Removing a DRAM Module
