1. Do not mix memory sizes. If installing 2 DIMMs, both DIMMs must be the same size.
2. Default SDRAM configuration is 512 MB. Bank 1 (U15) must be populated first. You can use one or both banks to configure
3. One 512-MB DIMM is the default shipping configuration.
4. Upgrades PRP to 1 GB by adding a second 512-MB DIMM.
5. This memory size is not supported.
If your system includes redundant PRPs, both PRPs should have the same memory size. Redundancy is
Note
not supported when using a GRP and a PRP in the same chassis. Cisco strongly recommends that you
avoid configuring your router using mixed route processor cards. Refer to the Route Processor
Redundancy Plus for the Cisco 12000 Series Router publication for more redundancy information.
Line Card Memory
There are two types of user-configurable line card memory on most line cards:
•
•
Line card memory configurations and memory socket locations differ, depending on the type of line card.
In general, all line cards share a common set of memory configuration options for route memory, but
support packet memory differently. For clarity in describing how to remove and install memory in this
publication, line cards fall into the following groups, based on certain physical characteristics:
