GRP, PRP, and Line Card Memory Overview

Figure 1

SIMM socket on the GRP.

The two route memory DIMM sockets on the GRP, labeled U39 (route memory bank 1) and U42 (route

memory bank 2), respectively, enable you to configure route memory in desired increments ranging from

128 to 512 MB.

Note

Table 1

default route memory configuration is 128 MB. If the GRP is currently equipped with one 64-MB DIMM

in socket U39, you can upgrade memory by installing a second 64-MB DIMM in socket U42, or by

removing the existing 64-MB DIMM and replacing it with one 128-MB DIMM.
