routers. Refer to the Router Memory Specifications table in the Overview of 2800 Routers chapter for
DRAM information.
Cisco 2811, Cisco 2821, and Cisco 2851 routers have two DIMM connectors and are designed to operate
with either one or two DRAM DIMMs installed, depending on the amount of memory needed. If only
one DRAM DIMM is used, it can be installed in either DIMM connector.
