Reinstall the SRPU
SDRAM modules are removable components on the SRPU. In the following cases, you need to
upgrade or replace an SDRAM module:
z More memory space is needed for application program upgrade.
z The router needs to maintain a large routing table or to support other highly memory consuming
operations.
z An existing SDRAM module is damaged.
Note that the SDRAM connectors are subject to a limitation on the number of times you can insert
SDRAM modules into them.
1. Locating the SDRAM module to be replaced on the SRPU
Before working on an SDRAM module, you need to locate it on the SRPU. Figure2 illustrates where the
SDRAM modules are on the SRPU of the SR8800.
